1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS Suunto D6i wristop dive computer is designed to help you get the most out of your diving. With integrated digital compass and gas switching, Suunto D6i simplifies your diving experience because all the information you need relating to depth, time, decompression status, optional tank pressure, and direction is available on one easy-to-read screen.
2. WARNINGS, CAUTIONS, AND NOTES Throughout this user's guide, important safety icons are displayed.
10 WARNING NOT FOR PROFESSIONAL USE! Suunto dive computers are intended for recreational use only. The demands of commercial or professional diving may expose the diver to depths and conditions that tend to increase the risk of decompression illness (DCI). Therefore, Suunto strongly recommends that the device not be used for any commercial or professional diving activities.
WARNING THERE IS ALWAYS A RISK OF DECOMPRESSION ILLNESS (DCI) FOR ANY DIVE PROFILE EVEN IF YOU FOLLOW THE DIVE PLAN PRESCRIBED BY DIVE TABLES OR A DIVE COMPUTER. NO PROCEDURE, DIVE COMPUTER OR DIVE TABLE WILL PREVENT THE POSSIBILITY OF DCI OR OXYGEN TOXICITY! An individual’s physiological make up can vary from day to day. The dive computer cannot account for these variations. You are strongly advised to remain well within the exposure limits provided by the instrument to minimize the risk of DCI.
12 WARNING DIVES WITH REQUIRED DECOMPRESSION STOPS ARE NOT RECOMMENDED. YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY WHEN THE DIVE COMPUTER SHOWS YOU THAT A DECOMPRESSION STOP IS REQUIRED! Note the blinking ASC TIME symbol and the upward pointing arrow. WARNING USE BACK-UP INSTRUMENTS! Ensure that you use backup instrumentation, including a depth gauge, submersible pressure gauge, timer or watch, and have access to decompression tables whenever diving with the dive computer.
WARNING YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! Flying or traveling to a higher altitude within the no-fly time can greatly increase the risk of DCI. Review the recommendations given by Divers Alert Network (DAN).
14 WARNING THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PERCENTAGE VALUES OF OXYGEN CONCENTRATION. DO NOT ROUND UP FRACTIONAL PERCENTAGES! For example, 31.8% oxygen should be entered as 31%. Rounding up will cause nitrogen percentages to be understated and will affect decompression calculations.
WARNING SET THE CORRECT PERSONAL ADJUSTMENT MODE! Whenever it is believed that factors that tend to increase the possibility of DCI exist, it is recommended that you use this option to make the calculations more conservative. Failure to select the correct Personal Adjustment setting will result in erroneous dive and planning data. WARNING DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury.
16 WARNING NEVER ASCEND ABOVE THE CEILING! You must not ascend above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling. WARNING DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND ENTERED THE ANALYZED VALUE INTO YOUR DIVE COMPUTER! Failure to verify cylinder contents and enter the appropriate O2% into your dive computer will result in incorrect dive planning information.
WARNING Traveling to a higher elevation can temporarily cause a change in the equilibrium of dissolved nitrogen in the body. It is recommended that you acclimatize to the new altitude by waiting at least three hours before diving. WARNING WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY TAKE ACTION TO REDUCE OXYGEN EXPOSURE.
18 WARNING Using the Suunto Dive Planner software is not a substitute for proper dive training. Diving with mixed gases has dangers that are not familiar to divers diving with air. To dive with trimix, triox, heliox and nitrox or all of them, divers must have specialized training for the type of diving they are doing. WARNING Always use realistic SAC rates and conservative turn pressures during dive planning.
NOTE It is not possible to change to AIR mode after a dive in NITROX mode, before the No-fly time has elapsed. When planning both air and nitrox dives during the same dive series, you should set the instrument in NITROX mode and modify the gas mix accordingly. NOTE In GAUGE mode the no-fly time is always 48 hours.

LONG PRESSING UP RESETS THE STOPWATCH. 4.3. AC water contacts The water and data transfer contact is located on the side of the case. When submerged, the water contact poles are connected by the conductivity of the water and the “AC” symbol appears on the display. The AC text is shown until the water contact deactivates.
Contamination or dirt on the water contact may prevent this automatic activation. Therefore, it is important that the water contact is kept clean. The contact can be cleaned with fresh water and a soft brush, for example a tooth brush. NOTE Water or moisture build-up around the water contact may cause the contact to activate automatically. This can happen, for example, when washing your hands or sweating.
IF ACCESSED FROM TIME MODE, TIME AND BEARING ARE DISPLAYED AT THE BOTTOM OF THE SCREEN. ACCESSED FROM DIVE MODE, CURRENT DEPTH, AND TIME OR MAXIMUM DEPTH, TANK PRESSURE, AS WELL AS BEARING OR DIVE TIME OR TEMPERATURE ARE DISPLAYED. NOTE When accessed from DIVE mode, toggle between the alternative displays by pressing the UP/DOWN buttons. 4.4.1. Compass display The Suunto D6i displays the compass as a graphical representation of a compass rose.
4.4.2. Locking a bearing A bearing can be locked to help you follow a selected course, and directional arrows point towards the locked bearing. The last locked bearing is stored and is available the next time the compass is activated. In the DIVE mode the locked bearings are also stored in the log. TO LOCK A BEARING, PRESS SELECT. The Suunto D6i also provides help for navigating square and triangular patterns, as well as navigating a return heading.
Symbol Explanation You are 180 degrees from the locked bearing You are 120 (or 240) degrees from the locked bearing 4.4.3. Compass settings You can define the compass settings (Calibration, Declination and Timeout) in the COMPASS mode: Calibration Because of changes in the surrounding magnetic field, the Suunto D6i electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field .
NOTE The unit will automatically enter the calibration sequence when taken into use for the first time. Strong electromagnetic fields, such as power lines, stereo speakers, and magnets can affect the compass calibration. Therefore, it is advisable to calibrate the compass if your Suunto D6i has been exposed to these fields. 36 NOTE When traveling overseas, it is recommended that you recalibrate the compass at the new location before using it.
To calibrate the compass: HOLD THE DEVICE LEVEL AND SLOWLY ROTATE 360°. THEN SLOWLY TURN THE DEVICE 90° TO VERTICAL POSITION. If the calibration fails several times in a row, it is possible that you are in an area with sources of magnetism, such as large metal objects, power lines or electric appliances. Move to another location and try to calibrate the compass again. If the calibration continues to fail, contact an authorized Suunto service center.
ADJUST WITH UP AND DOWN. ACCEPT WITH SELECT. Time-out You can set the compass time-out from 1 to 20 minutes. After the set time has passed from the latest button press, the dive computer returns to the TIME or DIVE mode from the COMPASS mode. ADJUST WITH UP AND DOWN. ACCEPT WITH SELECT. You can exit the COMPASS mode also by long pressing the SELECT button. 4.5. Apnea Timer You can use the Apnea Timer function for interval training in freediving. To set the Apnea Timer, follow these steps: 1.
2. In the Apnea Timer, long press DOWN to enter settings in which you can define the duration of the ventilation period and the incremental increase/decrease in time for each cycle (repetition). You can adjust values with the UP and DOWN buttons. 3. Short press SELECT, and define the number of cycles. 4. Start the first cycle by short pressing DOWN. The timer counts down the ventilation time, which is also indicated by two short beep tones. 5. Short press DOWN to start the Apnea cycle.

5. BEFORE DIVING Do not attempt to use the dive computer without reading this user's guide in its entirety, including all the warnings. Make sure that you fully understand the use, displays and limitations of the instrument. If you have any questions about the manual or the dive computer, contact your SUUNTO dealer before diving with the dive computer.
The Suunto D6i allows you to choose between a traditional Recommended Safety Stop and Deep Stops. Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation. In order to optimize the response to different increased risk situations, an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced. The combination of stop types depends on the user settings and the specific dive situation.
In the event that a required gas is not available at all, decompress for as long as you can by using the next most suitable gas that has the highest oxygen content. Notice that the oxygen content should be low enough to not violate the maximum partial pressure of oxygen (PO2). 5.3. Dive computer limitations While the dive computer is based on current decompression research and technology, you must realize that the computer cannot monitor the actual physiological functions of an individual diver.
WARNING Suunto recommends that you receive training in freediving techniques and physiology before conducting breath hold dives. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause a diver to commit errors that may lead to serious injury or death. 5.5. Audible and visual alarms The dive computer has audible and visual alarms that advise when important limits are approached or that prompt you to acknowledge preset alarms.
Instructional beep Sound pattern Interpretation Descending Start descending Descendingascending Change gas The visual information on the dive computer display is shown during the alarm breaks in order to save battery. Table 5.3. Audible and visual alarm types Alarm type High priority alarm followed by "Start ascending" beep, repeated for the maximum of three minutes. The PO2 value blinks. Alarm reason PO2 value is greater than the adjusted value. Current depth is too deep for the gas in use.

5.6. Error conditions The dive computer has warning indicators that alert you to react to certain situations that would significantly increase the risk of DCI. If you do not respond to its warnings, the dive computer will enter an Error mode, indicating that the risk of DCI has greatly increased. If you understand the dive computer and operate it sensibly, it is very unlikely you will ever put the instrument into the Error mode.
5.7.1. Installing the wireless transmitter When purchasing the Suunto D6i, we strongly recommend that you have your Suunto representative attach the transmitter to the first stage of your regulator. However, if you decide to attach it yourself, do the following: 1. Remove the high pressure (HP) port plug on the first stage of your regulator using an appropriate tool. 2. Thread the high pressure transmitter of the Suunto D6i into the HP port of your regulator with your fingers.
When there is no stored code, the Suunto D6i displays “cd:--” and receives data with lowered sensitivity from a very short distance only (0.1–0.5m / 0.5–1 ft). The flash symbol is not displayed at this phase. By taking the Suunto D6i unit close to the transmitter, it will store the received code and start receiving with full sensitivity and display data received with this code only. NOTE The pairing procedure only needs to be performed once, before the first use.
WARNING If there are several divers using a Suunto wireless transmitter, always ensure that each diver is using a different code before starting the dive. In case there are several divers using the same code, the transmitter's code must be changed before diving. To assign a new transmitter code: 1. Slowly open the cylinder valve fully to pressurize the system. 2. Immediately close the tank valve, and quickly depressurize the regulator so that the pressure is reduced to less than 10 bar/145 psi.
2. In the next menu, a Code number is displayed. Clear the code by short-pressing the UP button (toggle from “Ok” to “Clear”), and press the SELECT button. 3. 4. Short-press the MODE button to exit the DIVE settings. Take the Suunto D6i unit close to the transmitter (the system must be pressurized to above 15bar/300 psi). The dive computer displays the received new code number and then start displaying the transmitted cylinder pressure.
NOTE In order to save battery energy, the transmitter enters power saving mode with slower data transmission rate if the tank pressure remains unchanged for more than five (5) minutes. The transmitter continues transmitting with the saved code when any pressure change is detected (e.g., the user presses the purge button on regulator or breathes from the regulator). 5.7.3. Transmitting data After the pairing procedure, the Suunto D6i will receive cylinder pressure data from the transmitter.
Display Indication Figure no conn Text "no conn" is displayed when the unit receives no data packets from the transmitter. Pressure reading has not been updated for more than one minute. The latest valid pressure reading is displayed intermittently. The flash symbol is not displayed. Transmitter is out of range (>1.2 m/4 ft), in power saving mode or on another channel.
5.8. DIVE mode settings Suunto D6i has several user-definable functions, as well as depth and time-related alarms that you can set according to your personal preferences. The DIVE mode settings are dependent on the dive submode chosen (AIR, NITROX, GAUGE, FREE), so that, for example, nitrox settings are only available in the NITROX submode. The table below shows what DIVE settings are available in each DIVE submode. Table 5.5.
Setting AIR mode NITROX mode GAUGE mode FREE mode Surf time notify alarm X Sample rate X X Deep stop X X Air time X X Units X X X X X X The figure below shows how to enter the DIVE mode settings menu. USE UP AND DOWN BUTTONS TO TOGGLE BETWEEN DIVE SETTINGS. NOTE Some settings cannot be changed until five (5) minutes has elapsed after the dive.
5.8.1. Setting the nitrox values If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder (and additional gases) must always be entered into the computer to ensure correct nitrogen and oxygen calculations. In the NITROX setting mode, the equivalent maximum operating depth (MOD), based on the chosen setting, is displayed. After entering values for Mix1, you can set two additional mixes, Mix2 and Mix3. You can set Mix2 and Mix3 to "Primary", "Secondary" or "Off".
To view the most pessimistic ascent schedule, that is, a schedule for the situation in which the gases are not changed at all, you can set the mix gas(es) as Secondary gas, and the time it takes to finish the decompression using the current breathing gas is shown as the ASC time. Note however, that showing the most pessimistic ascent schedule during a long dive can easily result in the ascent time no longer fitting the reserved field and the dive computer displays "---" (max. 199 min).
5.8.2. Setting the personal/altitude adjustments The current Altitude and Personal Adjustment settings are displayed in the startup screen when entering the DIVE mode. If the mode does not match the altitude or personal conditions (refer to Section 5.9.4. Diving at altitude and Section 5.9.5. Personal adjustments), it is imperative that you enter the correct selection before diving. Use Altitude Adjustment to select the correct altitude and use Personal Adjustment to add an extra level of conservatism.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.4. Setting the tank pressure alarm The tank pressure alarm can be set "ON" or "OFF" and in the range of 10–200 bar. The alarm is the secondary cylinder pressure alarm point. The alarm is activated when the tank pressure drops below the set limit. You can acknowledge this alarm. The 50 bar/700 psi alarm, however, is fixed and cannot be changed. You can acknowledge this alarm. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.5.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.6. Setting the depth notify alarm (FREE mode) You can set five independent Depth Notify Alarms to indicate a certain depth, for example, start of free falling or mouth filling in freediving. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.7. Setting the dive-time alarm The Dive Time Alarm setting can be activated and used for several purposes to add to your diving safety.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. NOTE With a range of 1–999 minutes, the alarm can be set to your planned bottom time, for example. 5.8.8. Setting the surface time notify alarm (FREE mode) You can set the Surface Time Notify Alarm to indicate the length of the surface time before a new dive. Suunto D6i starts counting the time automatically when you surface (at 0.5 m/1.6 ft). ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.9.
The factory default setting is 20 seconds. You can set the dive profile sample rate in free dive to 1, 2, or 5 seconds. The sample rate for gauge, nitrox and air dives is 10, 20, 30, or 60 seconds. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.10. Setting the deep stops In the AIR mode in the Deep Stops setting mode, the Deep stops can be set “ON” or “OFF” depending on whether the Deep stops are used or not. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON.
5.8.11. Setting the air time In the Air Time setting mode, the remaining air time display can be set "ON" or "OFF" depending on whether estimated remaining air time display is used or not. Air Time can only be displayed when the wireless tank pressure transmitter is in use. 5.8.12. Setting the units In the Unit settings you are able to choose between metric (meters/Celsius/bar) and imperial (feet/Fahrenheit/psi) units. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.9.
5.9.1. Accessing DIVE mode The Suunto D6i has four diving modes: AIR mode for diving with standard air only, NITROX mode for diving with oxygen enriched mixtures, GAUGE mode for use as a bottom timer and FREE mode for freediving. The chosen dive mode is displayed when the DIVE mode is accessed, and you can toggle between the submodes by pressing the UP/DOWN buttons. 5.9.2. DIVE mode activation Unless the DIVE mode is set OFF, the dive computer activates automatically when submerged deeper than 0.5 m/1.
After activation, all graphical display elements are turned ON, and the backlight and the beep are activated. After this, the selected altitude and personal settings are displayed. A few seconds later the battery power indicator is shown, as well as the maximum operating depth (MOD, 66.2 m), O2% (21%) and PO2 (1.6) value. During a dive series (between two consecutive dives) the dive computer also displayes the current tissue saturation graph. A few seconds later the battery power indicator is shown.
A TISSUE SATURATION GRAPH IS DISPLAYED BETWEEN DIVES WHEN DIVE MODE IS ACTIVATED. ON X-AXIS THE FAST TISSUES ARE ON LEFT AND SLOW TISSUES ON RIGHT. ON Y-AXIS, CALCULATED PERCENTUAL TISSUE SATURATION VALUES BASED ON RGBM ARE SHOWN. Y-AXIS RANGES FROM 0% TO 100%. AS SURFACE TIME ELAPSES, TISSUE SATURATION PERCENTAGES DECREASE ACCORDINGLY.
• the oxygen partial pressure limits are set correctly For more information on the NITROX mode, please refer to Section 6.2. Diving in NITROX mode (DIVE Nitrox). The dive computer is now ready for diving. 5.9.3. Battery power indication Temperature or internal oxidation of the battery affect the battery voltage. If the instrument is stored for a long period, or used in cold temperatures, the low battery warning may be displayed even though the battery has enough capacity.
The optional wireless pressure transmitter sends out a low battery (batt) warning when its battery voltage is getting low. This is shown intermittently instead of the pressure reading. When you get this warning, the tank pressure transmitter's battery needs to be replaced. 5.9.4. Diving at altitude The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model.
WARNING Traveling to a higher elevation can temporarily cause a change in the equilibrium of dissolved nitrogen in the body. It is recommended that you acclimatize to the new altitude by waiting at least three (3) hours before diving. 5.9.5. Personal adjustments There are personal factors that can affect your susceptibility to DCI, which you can predict in advance, and input into the decompression model. Such factors vary between divers and also for the same diver from one day to another.
This feature is used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment setting with the help of Table 5.7, Personal Adjustment settings. In ideal conditions, retain the default setting, P0. If conditions are more difficult, or any of the factors which tend to increase the possibility of DCI exist, select P1, or even the most conservative P2.
5.10. Safety Stops Safety Stops are widely considered good diving practice for recreational diving, and are an integral part of most dive tables. The reasons for performing a Safety Stop include: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D6i displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.10.1.
5.10.2. Mandatory Safety Stops When the ascent rate exceeds 10 m/33 ft per minute continuously for more than five (5) seconds, the microbubble build-up is predicted to be more than is allowed for in the decompression model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.
WHEN CEILING AND STOP ARE DISPLAYED WITH DOWNWARD POINTING ARROW, IMMEDIATELY (WITHIN 3 MINUTES) DESCEND TO OR BELOW CEILING. If you continue to violate the Mandatory Safety Stop, the tissue calculation model is affected and the dive computer shortens the available no-decompression time for your next dive. In this situation, it is recommended that you prolong your surface interval time before your next dive. 5.11.
Enabling the deep stops does not disable Recommended Safety Stops. Mandatory Safety Stops, for example due to continuous ascent rate violations, are still prompted. If a deep stop is violated, it does not cause the dive computer to go into an error (Er) mode. However, a penalty time is added to the subsequent decompression. NOTE 76 With Deep Stops ON, the Recommended Safety Stops will still be activated at the end of the dive.
6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. The dive computer is easy to use and read. Each display shows only the data relevant to that specific diving mode. 6.1. Diving in the AIR mode (DIVE Air) This section contains information on diving with standard air. To activate the DIVE Air mode, please refer to Section 5.9.1. Accessing DIVE mode. DIVE HAS JUST BEGUN AND AVAILABLE NO-DECOMPRESSION TIME IS OVER 99 MINUTES SO NO VALUE IS DISPLAYED.
6.1.1. Basic dive data During a No-decompression dive, the following information is displayed: • your present depth in meters/feet • the available no-decompression time in minutes as NO DEC TIME • the ascent rate presented as a bar graph on the right side • the Diver Attention Symbol if surface interval should be prolonged (see Table 7.1, Alarms) DIVE DISPLAY - PRESENT DEPTH IS 15 M, NO-DECOMPRESSION STOP TIME LIMIT 46 MIN. MAXIMUM DEPTH DURING THIS DIVE WAS 21.5 M, ELAPSED DIVE TIME 22 MIN.
DOWN BUTTON TOGGLES BETWEEN MAXIMUM DEPTH, CURRENT TIME AND TANK PRESSURE. UP BUTTON TOGGLES BETWEEN DIVE TIME AND WATER TEMPERATURE. In addition, with the optional wireless transmission enabled: • the Remaining Air time in the left center window indicated as AIR TIME (Air Time must be set ON) • the cylinder pressure in bar (or psi) displayed in the lower left corner • the cylinder pressure graphically displayed on the left side 6.1.2.
To make a bookmark in the profile memory during a dive, press the SELECT button. A brief confirmation will be given. A BOOKMARK IS PLACED IN THE PROFILE MEMORY DURING A DIVE BY PRESSING THE SELECT BUTTON. 6.1.3. Tank pressure data When using the optional wireless pressure transmitter, the pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative display. Whenever you start a dive, the remaining air time calculation begins.
The change in your air consumption is based on constant one second interval pressure measurements over 30–60 second periods. An increase in air consumption influences the remaining air time rapidly, while a drop in air consumption increases the air time slowly. In this way, an over optimistic air time estimation, caused by a temporary drop in air consumption, is avoided. The remaining air time calculation includes a 35 bar/500 psi safety reserve.
Low Air Pressure Warnings The dive computer will warn you with two (2) audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/700 psi. Two (2) double beeps are also heard when the cylinder pressure goes down to the user-selected alarm pressure, and when the remaining time reaches zero. 6.1.4. Ascent rate indicator The ascent rate is displayed graphically along the right hand side with a vertical bar.
WARNING DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompression model will penalize your next dive(s). 6.1.5. Safety Stops A three (3) minute Recommended Safety Stop is prompted after every dive to over 10 m. 6.1.6.
6.1.7. Decompression dives When your NO DEC TIME becomes zero, your dive changes into a decompression dive. Therefore, you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear. An upward pointing arrow will also prompt you to start your ascent. If you exceed the no-decompression limits on a dive, the dive computer will provide the decompression information required for ascent.
WARNING YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE INSTRUMENT! The ascent time will increase if you: • remain at depth • ascend slower than 10 m/33 ft per minute or • make your decompression stop deeper than at the ceiling These factors will also increase the amount of air required to reach the surface. Ceiling, ceiling zone, floor and decompression range When in decompression, it is important that you understand the meaning of ceiling, floor, and decompression range.
The depth of the ceiling and floor depends on your dive profile. The ceiling depth will be fairly shallow when you enter the decompression mode, but if you remain at depth, it will move downward and the ascent time will increase. Likewise, the floor and ceiling may change upwards while you are decompressing. When conditions are rough, it may be difficult to maintain a constant depth near the surface.
Display below the floor The blinking ASC TIME sign and an upward pointing arrow indicate that you are below the floor. You should start your ascent immediately. The ceiling depth is shown on the left side, and the minimum total ascent time on the right side of the center window. Below is an example of a decompression dive without Deep Stops, below the floor. UPWARD POINTING ARROW, BLINKING ASC TIME AND AN ALARM TELL YOU TO ASCEND. MINIMUM TOTAL ASCENT TIME INCLUDING SAFETY STOP IS 9 MINUTES.
Display at the ceiling zone When you reach the ceiling zone, the display will show you two arrows pointing at each other (the “hour glass” icon). Below is an example of a decompression dive at the ceiling zone. TWO ARROWS POINT AT EACH OTHER “HOUR GLASS”. YOU ARE IN THE OPTIMUM CEILING ZONE AT 3 M AND YOUR MINIMUM ASCENT TIME IS 9 MINUTES. During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling.
DECOMPRESSION DIVE, ABOVE CEILING. NOTE DOWNWARD POINTING ARROW, ER WARNING AND ALARM. YOU SHOULD IMMEDIATELY (WITHIN 3 MINUTES) DESCEND TO OR BELOW CEILING. In addition, an Error warning (Er) reminds you that you have only three (3) minutes to correct the situation. You must immediately descend to, or below, the ceiling. If you continue to violate the decompression, the dive computer will go into a permanent Error Mode. In this mode, the instrument can only be used as a depth gauge and timer.
to be understated and will affect decompression calculations. If you want to adjust the computer to provide more conservative calculations, use the personal adjustment feature to affect decompression calculations, or reduce the PO2 setting to affect oxygen exposure according to the entered O2% and PO2 values. Calculations based on nitrox use result in longer no-decompression times and shallower maximum depths than diving with air.
6.2.2. Oxygen displays When the NITROX mode is activated, the display will show the information in the figure below. In the NITROX mode, the maximum operational depth is calculated based on set O2% and PO2 values. NITROX DIVE MODE ACTIVATION. MAXIMUM OPERATIONAL DEPTH BASED ON SET O2 % (21%) AND PO2 (1.4 BAR) IS 53.6 M.
DOWN BUTTON TOGGLES BETWEEN O2, MAXIMUM DEPTH CURRENT TIME AND TANK PRESSURE. UP BUTTON TOGGLES BETWEEN PO2, OLF%, DIVE TIME AND WATER TEMPERATURE. 6.2.3. Oxygen limit fraction (OLF%) If set to the NITROX mode, in addition to tracking the diver's exposure to nitrogen, the instrument tracks the exposure to oxygen. These calculations are treated as entirely separate functions.
6.2.4. Gas change and multiple breathing gas mixes One of the special features in Suunto D6i is the possibility to set two additional nitrox mixes to be used during a dive. This feature can be activated by setting the Mix2 and Mix3 as a Primary (or Secondary) gas, and entering other parameters in the same way as with the Mix1 gas. Mix2 and Mix3 settings are held until you change them (they will not return to default settings automatically). A dive is always started with Mix1.
NOTE If no button is pressed in 15 seconds, the dive computer will go back to the dive display without changing the gas mix. Upon ascent, the computer prompts you to change gas when the PO2 level you have set for the next mix allows a gas change. The prompt is a low priority alarm followed by the "Change gas" beep, sounded once. The Gas mix (O2%) value blinks. 6.3. Diving in the GAUGE mode (DIVE Gauge) If set to the GAUGE mode, the dive computer can be used as a bottom timer.
NOTE There is no ascent rate monitoring in the GAUGE mode. NOTE If you dive with the GAUGE mode, it is not possible to change between the modes before the no fly time has counted down. In GAUGE mode, the no-fly time is always 48 hours. 6.4. Diving in the FREE mode (DIVE Free) If set to the FREE mode, the dive computer can be used as a free diving instrument. In the FREE mode, the total dive time is always displayed in minutes and seconds (mm:ss) in the center window.
NOTE The FREE mode does not provide decompression information. NOTE There is no ascent rate monitoring in the FREE mode. 6.4.1. Day History The Day History function shows the free dive history of your latest diving day. In the SURFACE mode you can enter the Day History by pressing the SELECT button.
NOTE The first dive of the next day will reset the Day History function and start a new one. 6.4.2. Free dive time limit The FREE mode has a time limit of 10 minutes. After 10 minutes, Suunto D6i will automatically change from Free Dive to Scuba Bottom Timer (GAUGE). After the dive, the no-fly time will countdown from 48 hours. Also, you will not be able to dive in AIR or NITROX modes until the no-fly time has counted down to zero. You can only set the DIVE mode to GAUGE or OFF.
7. AFTER DIVING Once back at the surface, Suunto D6i continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety. Table 7.1. Alarms Symbol on display Indication Diver Attention Symbol - Extend Surface Interval Violated Decompression Ceiling or Too Long Bottom Time Do Not Fly Symbol 7.1. Surface interval An ascent to any depth shallower than 1.
Or, in the alternative displays, the following information will be shown: • maximum depth of last dive in meters/feet • dive time of last dive in minutes, shown as DIVE TIME • the current time, shown as TIME • the current temperature in °C/°F • cylinder pressure in bar/psi (if enabled) If set to NITROX mode, the following information will also be shown: • the oxygen percentage labeled O2% • the oxygen partial pressure labeled PO2 • the current oxygen toxicity exposure labeled OLF% 7.2.
7.2.1. FREE Dive Each dive series includes dives that have been performed during one day. The day's dive numbering and latest dive information resets to 0 at midnight, and each day there is a new series of dives that is recorded in the log book. The dive is completed once you ascend beyond 0.5 m. A new dive will be registered in the log book immediately you descend once again. 7.3.
• • • A minimum surface interval of 12 hours would be required in order to be reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jetliner (altitude up to 2,400 m/8,000 ft). Divers who plan to make daily, multiple dives for several days, or make dives that require decompression stops, should take special precautions and wait for an extended interval beyond 12 hours before a flight.
By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3 m/10 ft increments ending at 45 m/150 ft. No-decompression limits longer than 99 minutes are displayed as “—“. During a dive series (between two consecutive dives) it is also possible to enter the surface interval time as a planning parameter. If the O2% is too high for the planned depth, NA is displayed instead of a numerical no-decompression limit.
• any calculated residual nitrogen • all dive history for the past four days The no-decompression times given for different depths will therefore be shorter than before your first “fresh” dive. You can exit the DIVE PLANNING mode by pressing the MODE button. NOTE The DIVE PLANNING mode is disabled in GAUGE mode and in Error mode (see Section 5.6. Error conditions). The DIVE PLANNING mode calculates no-decompression times for Mix1 only.
7.6. MEMORY mode The memory options in the MEMORY mode include dive logbook (MEM Logbook) and dive history (MEM History). They are accessed from the DIVE mode and you can toggle between them by using the UP/DOWN buttons. The dive entry time and date is registered in the Logbook memory. Always check before diving that the time and date are correctly set, especially after travelling between different time zones. 7.6.1.
THERE ARE THREE PAGES OF LOGBOOK DIVE INFORMATION. USE SELECT BUTTON TO SCROLL BETWEEN LOGBOOK PAGES I, II, AND III. THE DATA OF THE MOST RECENT DIVE IS SHOWN FIRST. YOU CAN SCROLL THE GRAPHICAL DIVE PROFILE ON PAGE III WITH UP BUTTON.
Page III • depth/time profile of the dive • water temperature • tank pressure (if enabled) NOTE Memory capacity depends on the selected sample rate. With factory default setting (20 s) and without transmitter data the capacity is approximately 140 hours. With transmitter data the capacity is minimum 35 hours. In Dive Free mode the maximum memory capacity is 35 hours. After that, when new dives are added, the oldest dives are deleted.
DIVE HISTORY DISPLAY. TOTAL NUMBER OF DIVES, DIVE HOURS AND MAXIMUM DEPTH. The Dive History Memory can hold a maximum of 999 dives and 999 diving hours. When these maximum values are reached, the counters will start again from zero. NOTE The maximum depth can be reset to 0.0 m/0 ft using the PC Interface cable and the downloadable Suunto DM4 software.
The Free Dive history gathers history of the entire sequence of free dives. Unlike the day history, the Free Dive History is not reset. 7.7. Suunto DM4 The Suunto DM4 is an optional software that greatly enhances the functionality of your Suunto D6i. With the DM4 software, you can download dive data from your dive computer to your laptop. After that, you can view and organize all the data recorded with your Suunto D6i.
• additional dive information (for example, SLOW and Mandatory Safety Stop violations, Diver Attention Symbol, Bookmark, Surfaced Mark, Decompression Stop Mark, and Ceiling Error Mark) • dive computer serial number • personal information (30 characters) By using the DM4, you are able to enter setup options such as: • input a personal, 30-character field into the Suunto instrument. • manually add comments, multimedia and other personal information to the PCbased dive data files 7.8.
3. 110 Follow the instructions on the DM4 on how to transfer your dives to your Movescount.com account.
8. CARE AND MAINTENANCE OF MY SUUNTO DIVING COMPUTER The SUUNTO dive computer is a sophisticated precision instrument. Although it is designed to withstand the rigors of scuba diving, you must treat it with the same proper care and caution as any other precision instrument. • WATER CONTACTS AND PUSH BUTTONS Contamination or dirt on the water contacts/connector or push buttons may prevent the automatic activation of the Dive Mode and cause problems during the data transfer.
• • • • • • • • 112 Should moisture appear inside the case or battery compartment, immediately have the instrument checked by your SUUNTO service center. The specific scratch guard for D6i is designed to help the display from getting scratched. They can be purchased separately from your nearest retailer. The scratch guard is easy to attach and also to replace if needed (for more information, see the instructions on www.suunto.com).
MAINTENANCE The instrument should be soaked, thoroughly rinsed with fresh water, then dried with a soft towel after each dive. Make sure that all salt crystals and sand particles have been flushed out. Check the display for possible moisture or water. DO NOT use the dive computer if you detect any moisture or water inside. Contact an authorized Suunto service center for battery replacement or other service. CAUTION! • Do not use compressed air to blow water off the unit.
9. BATTERY REPLACEMENT NOTE It is advisable to contact an authorized Suunto service center for battery replacement. It is imperative that the change is made in a proper manner to avoid any leakage of water into the battery compartment or computer. CAUTION When the battery is changed, all nitrogen and oxygen uptake data is lost. Therefore, the no-fly time shown by the computer should have reached zero or you must wait for 48 hours, or preferably up to 100 hours, before you dive again.
9.1.1. Transmitter battery kit The transmitter battery kit includes a 3.0 V CR ½ AA lithium cell battery and a lubricated O-ring. When handling the battery, do not make contact with both of the poles at the same time. Do not touch the metal surfaces of the battery with your bare fingers. 9.1.2. Required tools • A Phillips-head screwdriver • Soft cloth for cleaning 9.1.3. Replacing the transmitter battery To change the transmitter battery: 1. Remove the transmitter from the regulator HP port. 2.
8. Gently insert the new battery into the battery compartment. Check the polarity of the battery. The "+" mark should point toward the top of the compartment and the "-" mark towards the bottom. NOTE It is imperative that you wait at least 30 seconds before re-installing the transmitter battery. When the battery is re-installed, the transmitter sends an overpressure (“---“) signal on code 12 for 10 seconds, after which it goes to normal operation, and shuts down after five (5) minutes. 9.

NOTE Low temperature or an internal oxidation of the battery may activate the battery warning even though the battery has enough capacity. In this case, the warning usually disappears when the DIVE mode is activated again. 10.2. Suunto RGBM The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algorithm for predicting both dissolved and free gas in the tissues and blood of divers. It was developed in co-operation between Suunto and Bruce R. Wienke BSc, MSc, PhD.
10.2.1. Suunto RGBM adaptive decompression The Suunto RGBM algorithm adapts its predictions of both the effects of microbubble build-up and adverse dive profiles in the current dive series. It also changes these calculations according to the personal adjustment you select. The pattern and speed of decompression at the surface is adjusted according to microbubble influence. On repetitive dives, adjustment may also be applied to the maximum allowable nitrogen overpressure in each theoretical tissue group.
10.2.2. No-decompression limits for air The no-decompression limits displayed by the dive computer for the first dive to a single depth (see Table 10.1, No-decompression time limits for various depths (m) and Table 10.2, No-decompression time limits for various depths (ft)), are slightly more conservative than those permitted by the U.S. Navy tables. Table 10.1.

Altitude diving The atmospheric pressure is lower at high altitudes than at sea level.
As a result, the allowed no-decompression-stop limits are considerably reduced. 10.3. Oxygen exposure The oxygen exposure calculations are based on currently accepted exposure time limit tables and principles. In addition to this, the dive computer uses several methods to conservatively estimate the oxygen exposure. For example: • The displayed oxygen exposure calculations are raised to the next higher percentage value. • The CNS % limits up to1.
