1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS Suunto DX wristop dive computer is designed to help you get the most out of your diving. Suunto DX is the world’s first wristop sized dive computer to integrate rebreather and trimix compatibility, a tilt-compensated 3D digital compass, and wireless tank pressure reception into one compact unit.
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 sickness (DCS). Therefore, Suunto strongly recommends that the device not be used for any commercial or professional diving activities.
WARNING SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS LIMIT THEIR MAXIMUM DEPTH TO 40 M/130 FT OR TO THE DEPTH CALCULATED BY THE COMPUTER BASED ON THE SELECTED O2% AND A MAXIMUM PO2 OF 1.4 BAR! Exposure to greater depths increases the risk of oxygen toxicity and decompression sickness. WARNING DIVES WITH REQUIRED DECOMPRESSION STOPS ARE NOT RECOMMENDED.
12 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 DCS. Review the recommendations given by Divers Alert Network (DAN).
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.
14 WARNING SET THE CORRECT PERSONAL ADJUSTMENT MODE! Whenever it is believed that factors that tend to increase the possibility of DCS 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.
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.
16 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.
WARNING Always use realistic SAC rates and conservative turn pressures during dive planning. Overly optimistic or erroneous gas planning can result in the exhaustion of breathing gas during decompression or in a cave or a wreck. WARNING ENSURE THE WATER RESISTANCE OF THE DEVICE! Moisture inside the device and/or battery compartment may seriously damage the unit. Only an authorized SUUNTO service center should do service activities.
18 CAUTION Only use a clean and dry Suunto USB Cable. Clean and dry the connector surfaces before use to prevent damage to the Suunto dive computer. CAUTION Only attach Suunto USB Cable to the data transfer contact on the Suunto dive computer. CAUTION Never lift or carry your cylinder by holding the wireless tank pressure transmitter as this may break the cover and cause flooding of the unit.

A separate stopwatch (dive timer) can also be used in the DIVE mode. For more information, refer to Section 6.1.6. Stopwatch (Timer).
USE DOWN BUTTON TO START STOPWATCH AND TAKE A SPLIT TIME. THE UP BUTTON STOPS THE STOPWATCH. IF YOU HAVE TAKEN SPLIT TIMES, YOU CAN SCROLL THEM BY SHORT PRESSING THE UP BUTTON. 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 DX 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 DX 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 DX 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 DX has been exposed to these fields. 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 THE UNIT IN A LARGE "INFINITY LOOP" UNTIL THE DEVICE BEEPS AND TEXT PASSED APPEARS. If the calibration fails several times in a row (text “Try Again” appears), 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 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.
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.
TM 5.1. The Suunto Fused RGBM Suunto Fused RGBM is an expanded version of the Suunto Technical RGBM. It additionally incorporates Dr. Bruce Wienke’s FullRGBM, which is the most complete bubble model in existence today. As the FullRGBM developed by Dr. Wienke is intended only for deep decompression dives, the Suunto Fused RGBM utilizes Suunto Technical RGBM for <40m dives.
For technical dives, you must have the dive plan created and available on the dive e.g., on a slate. You must also have a back-up plan for lost gases. In the unlikely event that the dive computer malfunctions during a dive, start using an alternative depth gauge and timer and following the ascent schedule and gas switches that are on your slate. 5.3.
Table 5.2. Instructional beep Sound pattern Interpretation Ascending Start ascending 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.
Alarm type Alarm reason High priority alarm followed by "Change gas" beep, sounded two times. The PO2 value blinks. PO2 value is smaller than 0.18 bar. In DIVE Mixed and DIVE CCR modes only. The depth is too shallow and the ambient pressure is too low for the current gas. The oxygen content is too low to keep you conscious. You should immediately switch the gas. High priority alarm followed Decompression ceiling depth is exceeded.
Alarm type Alarm reason Low priority alarm followed by "Change gas" beep, sounded once. The Gas mix value (O2%, O2%|He%) blinks. Gas change is recommended. In DIVE Mixed and DIVE CCR modes only. You should change to a gas more favorable to decompression. ASC TIME assumes that the gas is changed and is accurate only if you change the gas accordingly.
Alarm type Alarm reason Low priority alarm, sounded two times. The Tank pressure symbol blinks. Cylinder pressure reaches the selected alarm pressure, 10 - 200 bar. Cylinder pressure reaches the fixed alarm pressure, 50 bar. This alarm operates only if the pairing to the wireless tank pressure transmitter is performed correctly and the transmission of tank pressure data is not disrupted during the dive for any reason. You can acknowledge the alarm.
NOTE When the tones are turned OFF, the alarms are not sounded when an alarm is activated. WARNING WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY TAKE ACTION TO REDUCE OXYGEN EXPOSURE. Failure to take action to reduce oxygen exposure after the warning is given can rapidly increase the risk of oxygen toxicity, injury, or death. 5.5.
When the dive computer is in the permanent Error mode, only the Er warning is shown in the center window. The dive computer does not show times for ascent or stops. However, all the other displays function as before to provide information for ascent. On an intended no-deco dive, you should immediately ascend to a depth of 3 to 6 m/10 to 20 ft and remain at this depth until air supply limitations require you to surface.
2. 3. Thread the high pressure transmitter of the Suunto DX into the HP port of your regulator with your fingers. DO NOT OVERTIGHTEN! Maximum torque is 6 Nm/4.4 lbsft or 53 lbsin. The seal is based on a static O-ring, not force! Attach the regulator to the scuba cylinder and slowly open the valve. Check for leaks by submerging the regulator first stage in water. If leaks are detected, check the condition of the O-ring and sealing surfaces. 5.6.2.
To pair the transmitter and the Suunto DX dive computer: 1. Ensure that the transmitter is properly attached to the regulator’s HP port and that the regulator is properly attached to the cylinder. 2. Ensure that the Suunto DX is turned on, and that the wireless integration is enabled in the Suunto DX settings (Tank Press is set ON. For more information, refer to Section 5.8.5. Setting the tank pressure pairing). If the Suunto DX is in the TIME mode, enter the DIVE mode by short-pressing the MODE button.
The transmitter assigns a new code automatically. NOTE To pair on the new transmitter code, the Suunto DX code must be cleared first. To re-pair the transmitter with the new code and the Suunto DX dive computer: 1. In the DIVE mode of the Suunto DX, long-press the DOWN button to enter the DIVE settings. Enter the Tank Press Pairing menu (Refer to Section 5.8.5. Setting the tank pressure pairing).
4. Take the Suunto DX 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. The wireless transmitter indicator (flash symbol) is displayed every time the Suunto DX receives a valid signal.
Display Indication --- Figure The flash symbol is blinking. Pressure reading exceeds allowed limit (over 360 bar/5220 psi). C 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.
5.7. Accessing DIVE mode The Suunto DX has four diving modes: AIR mode for diving with standard air only, MIXED mode for diving with oxygen and/or helium mixtures, CCR for rebreather diving, and GAUGE mode for use as a bottom timer. 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. PRESS MODE TO ENTER THE DIVE MODE SELECTION, THEN QUICKLY TOGGLE THROUGH THE SUBMODES BY PRESSING UP BUTTON. 5.8.
Table 5.5.
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 CC gases If set to the DIVE CCR mode, the correct oxygen and helium percentages of the diluent gas(es) in your diluent cylinder(s) must always be entered into the dive computer to ensure correct tissue and oxygen calculation.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. After entering values for Diluent 1, you can set additional diluents, Diluent 2 and Diluent 3, similarly. You can set these to “ON” or “OFF”. Diluent 1 is always set as an “ON” gas whereas Diluent 2 and Diluent 3 are “OFF” by default. WARNING Only enable the diluent(s) you actually have available and remember to check the set values before every dive to ensure they are correct. 5.8.2.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. When in the MIXED or CCR OC Gases setting mode, the equivalent maximum operating depth, based on the chosen setting, is also be displayed. After entering values for Mix1, you can set additional mixes, Mix2–Mix8, similarly. You can set them to "PRIMARY", "SECONDARY" or "OFF". Mix1 is always set as a primary gas. In order to minimize the risk of error during a dive, it is highly recommended that the mixes are set in the proper order.
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. 999 min). NOTE While setting the gases, notice that the calculated maximum operating depth is displayed in the upper field. You cannot change to this gas before you have ascended above this depth. In MIXED and CCR OC Gases mode, the default oxygen percentage (O2%) setting is 21% (air) and oxygen partial pressure (PO2) setting 1.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. The default setting for High Set Point is PO2 1.3 bar (range 1.0-1.5 bar). ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. Switch High depth can be set ON or OFF. ON means automatic switch to high set point at the defined depth, OFF means manual set point switching. The default setting for Switch High is ON, 20.0 m / 70 ft (range 15.0-60.0m / 50-200 ft).
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. Switch Low depth can be set ON or OFF. ON means automatic switch to low set point at the defined depth, OFF means manual set point switching. The default setting for Switch Low is OFF, 4.5 m / 15 ft (range 3.0-15.0 m / 10-50 ft).
The picture above illustrates a CCR dive using set points (Low Set Point 0.7 / High Set Point 1.3) and automatic high (Switch High ON 20 m) and low (Switch Low ON 10 m) set point switching. For shallow water (<6m/ 20 ft) decompression the Switch Low can be turned OFF.
5.8.4. 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 5.10.3. Diving at altitude and Section 5.10.4. 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. 5.8.6. Setting the tank pressure alarm The tank pressure alarm can be set "ON" or "OFF" and in the range of 10–200 bar / 200-3000 psi. 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.
5.8.7. Setting the depth alarm The Depth Alarm setting is factory-set to 30 m/100 ft, but you can adjust it according to your personal preference, or switch it off altogether. The depth range can be set from 3 m to 300 m/10 ft to 984 ft. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.8. 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.
5.8.9. Setting the sample rate The Sample Rate setting controls how often the depth, tank pressure (if enabled), and water temperature is stored in the memory. The factory default setting is 20 seconds (user selectable to 10, 20, 30, or 60 s). ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.10. Setting the deep stops In the DIVE 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.
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. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.9.
NOTE As a safety precaution, the oxygen calculations in the dive computer are made with an oxygen percentage of 1% + set O2%. When the dive computer is set in MIXED mode, the Dive Planning mode calculates using the O2% and PO2 values that are currently in the computer. To set the nitrox, trimix and/or heliox mixes, refer to Section 5.8.2. Setting the opencircuit gases. 5.9.1.
5.10.1. DIVE mode activation Unless the DIVE mode is set OFF, the dive computer activates automatically when submerged deeper than 0.5 m/1.5 ft. However, it is necessary to activate the DIVE mode BEFORE diving to check the cylinder pressure, altitude and personal adjustment settings, battery condition, oxygen settings, and so on. After activation, all graphical display elements are turned ON, and the backlight and the beep are activated.
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 TECHNICAL RGBM ARE SHOWN. Y-AXIS RANGES FROM 0% TO 100%. AS SURFACE TIME ELAPSES, TISSUE SATURATION PERCENTAGES DECREASE ACCORDINGLY.
the pressure transmitter is working (flash symbol blinks, cylinder pressure is displayed), and that there is no low battery warning displayed • you have enough air for your planned dive.
If the battery symbol is displayed in the Surface mode, or if the display is faded or weak, the battery may be too low to operate the dive computer, and battery replacement is recommended. NOTE For safety reasons, the backlight cannot be activated when the low battery warning is indicated by the battery symbol. 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.
Alt. adjustment Altitude range value A1 300–1500 m / 1000–5000 ft A2 1500–3000 m / 5000–10 000 ft NOTE Section 5.8.4. Setting the personal/altitude adjustments describes how the Altitude value is set. 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. 5.10.4.
• dehydration • personal settings in AIR/MIXED/CCR mode • previous history of DCS • stress • obesity • patent foramen ovale (PFO) • exercise on or after dive 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.
Table 5.7.
5.11. 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 DCS, microbubble reduction, ascent control, and orientation before surfacing. The Suunto DX displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.11.1.
5.11.2. 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 Fused 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 may shorten 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. 5.12. Deep stops In Suunto DX deep stops are activated on all dives below 20 m / 66 ft.
NOTE 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 5.7. 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 air 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 and Deep Stops A three (3) minute Recommended Safety Stop is always prompted after every dive to over 10 m, regardless if deep stops are enabled or disabled.
START AND STOP THE TIMER BY PRESSING SELECT BUTTON. 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.
• • the time needed at the Mandatory Safety Stop (if any) the time needed to reach the surface after the ceiling and Safety Stops have been completed 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 breathing gas required to reach the surface.
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.
ACTIVATION DISPLAY BRIEFLY SHOWS THE MAXIMUM OPERATING DEPTH, PERSONAL/ALTITUDE SETTINGS, O2%|HE VALUES AND PO2 VALUE (IN CCR MODE THIS IS THE CURRENTLY SELECTED SET POINT) If diving in the MIXED or CCR mode, the Suunto DX will additionally show on the alternative display (press UP and DOWN buttons to toggle values): • the oxygen and helium percentage, labeled O2%/He • the set oxygen partial pressure limit, labeled PO2 (MIXED mode) • the selected set point, labeled PO2 (CCR mode) • the current oxygen toxic
UP BUTTON TOGGLES BETWEEN PO2, OLF%, DIVE TIME AND WATER TEMPERATURE. 6.2.2. Oxygen limit fraction (OLF%) If set to the MIXED or CCR mode, in addition to tracking the diver's exposure to inert gas, the instrument tracks the exposure to oxygen. These calculations are treated as entirely separate functions. The dive computer calculates separately for Central Nervous System oxygen toxicity (CNS) and Pulmonary Oxygen toxicity, the latter measured by the addition of Oxygen Toxicity Units (OTU).
NOTE Mix number, O2%, He% and PO2 for the mixes are shown when scrolling. If the set PO2 limit is exceeded, it will be shown with the PO2 value blinking. The dive computer does not allow you to change to a gas whose set PO2 is exceeded. In such a case, the mix is shown but cannot be selected. If the PO2 is less than 0.18 bar, the dive computer gives an alarm. NOTE If no button is pressed in 15 seconds, the dive computer will go back to the dive display without changing the gas mix.
ENTER THE SELECTION MENU BY LONG PRESSING UP BUTTON, THEN SCROLL BY PRESSING UP BUTTON. The high and low set points or a custom set point can be adjusted during the dive. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON.
Diluent change during dive: CHANGING DILUENT. LONG PRESS UP, THEN ENTER THE CC DILUENT MENU. SCROLL THROUGH ENABLED DILUENTS BY PRESSING UP BUTTON. SELECT NEW DILUENT BY PRESSING THE SELECT BUTTON. Enabled open-circuit gas changes are made in the same way and at the same time the CC dive changes to an open-circuit (OC) dive. This feature is useful in bail-out situation. ENTER THE SELECTION MENU BY LONG PRESSING UP BUTTON, THEN SCROLL TO OC MIX BY PRESSING UP BUTTON. CONFIRM SELECTION WITH SELECT BUTTON.
6.2.5. Hyperoxic and hypoxic mixes in CCR Suunto DX displays text HYPER if the Diluent gas PO2 at the current depth is over 1.6. Text HYPOX is displayed if the Diluent gas PO2 at the current depth is less than 0.18. 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. In the GAUGE mode, the total dive time is always displayed in minutes in the lower right corner.
NOTE The GAUGE mode does not provide decompression information. NOTE There is no ascent rate monitoring in the 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.
7. AFTER DIVING Once back at the surface, Suunto DX 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 MIXED or CCR mode, the following information will also be shown: • the oxygen and helium percentages, labeled O2%/He • the oxygen partial pressure labeled PO2 • the current oxygen toxicity exposure labeled OLF% 7.2.
7.3. Repetitive dive planning The Suunto DX includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual inert gas loading of previous dives into consideration. The DIVE PLANNING mode is explained in Section 7.5. DIVE PLANNING mode (PLAN NoDec). 7.4. Flying after diving In the DIVE mode, the no-fly time is displayed in the center window next to the airplane image. In the TIME mode, the airplane image is shown in the top left corner.
• • 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. Further, the Undersea and Hyperbaric Medical Society (UHMS) suggests divers using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in an aircraft with cabin pressure up to 2,400 m/8,000 ft.
WHEN ENTERING THE PLAN MODE THE DISPLAY FIRST BRIEFLY SHOWS THE REMAINING DESATURATION TIME BEFORE GOING INTO PLAN MODE. USE UP AND DOWN BUTTONS TO SCROLL NO-DECOMPRESSION LIMITS AT DIFFERENT DEPTHS. YOU CAN ALSO ADJUST YOUR SURFACE INTERVAL TIME TO YOUR PLAN. NO-DECOMPRESSION LIMITS LONGER THAN 99 MINUTES ARE DISPLAYED AS “–”.
NOTE The DIVE PLANNING mode is disabled in GAUGE mode and in Error mode (see Section 5.5. Error conditions). The DIVE PLANNING mode calculates no-decompression times for Diluent 1 / Mix1 only. If additional mixes are enabled in the MIXED or CCR mode, they do not affect the calculations in (PLAN NoDec) mode. Higher Altitude and conservative Personal Adjustment settings will shorten the nodecompression time limits.
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. Dive logbook (MEM Logbook) The Suunto DX has a very sophisticated, high capacity Logbook and Profile Memory. The data is recorded in the profile memory based on the selected sample rate. The END OF LOGS text is displayed between the oldest and most recent dive.
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. LONG-PRESS UP BUTTON TO AUTO-SCROLL THE DIVE PROFILE GRAPH FORWARD.
• consumed pressure (if enabled) • warnings • OLF% (AIR, MIXED, CCR) Page III • depth/time profile of the dive • water temperature • tank pressure (if enabled) • gas changes (MIXED, CCR) • set point changes (CCR) 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. After that, when new dives are added, the oldest dives are deleted.
7.6.2. Dive history The dive history is a summary of all the dives recorded by the dive computer. The following information will be shown on the display: 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.

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 decompression model development Suunto's decompression model development originates from the 1980s when Suunto implemented Bühlmann's model based on M-values in Suunto SME.
In Suunto Fused RGBM the tissue half-times are derived from Wienke’s FullRGBM where human body is modeled by fifteen different tissue groups. FullRGBM can utilize these additional tissues and model the on-gassing and off-gassing more accurately. The amounts of nitrogen and helium on-gassing and off-gassing in the tissues are calculated independently from each other. The advantage of Suunto Fused RGBM is additional safety through its ability to adapt to a wide variety of situations.
CAUTION Always use the same personal and altitude adjustment settings for the actual dive than for the planning. Increasing the personal adjustment setting from the planned setting as well as increasing the altitude adjustment setting can lead to longer decompression times deeper and thus to larger required gas volume. You can run out of breathing gas underwater if the personal adjustment setting has been changed after dive planning. 10.2.2.
The displayed oxygen exposure calculations are raised to the next higher percentage value. • The CNS % limits up to1.6 bar are based on 1991 NOAA Diving Manual limits • The OTU monitoring is based on the long-term daily tolerance level and the recovery rate is reduced. Oxygen related information displayed by the dive computer is also designed to ensure that all warnings and displays occur at the appropriate phases of a dive.
10.4. Isobaric counterdiffusion (ICD) ICD is the term used to describe the physiologic effect when the diffusion of different gases occurs in opposite directions while under a constant ambient pressure. Particularly in diving, the gases are nitrogen and helium. ICD can produce the formation of bubbles in tissues where the sum of helium and nitrogen pressures exceeds ambient pressure.
