1. WELCOME TO THE WORLD OF SUUNTO DIVING INSTRUMENTS Suunto Vyper2 was designed to help you get the most out of your diving. After reading this manual and becoming familiar with the functions of your dive computer, you'll be ready to take the plunge into a whole new world of diving.
2. WARNINGS, CAUTIONS, AND NOTES Throughout this manual, important safety icons are displayed.
WARNING DIVES THAT REQUIRE 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! Make sure that you use back-up instrumentation, including a depth gauge, submersible pressure gauge, timer or watch, and have access to decompression tables whenever diving with the dive computer.
WARNING SELECT THE CORRECT ALTITUDE ADJUSTMENT SETTING! When diving at altitudes greater than 300 m/1,000 ft the Altitude Adjustment feature must be correctly selected in order for the computer to calculate the decompression status. The dive computer is not intended for use at altitudes greater than 3,000 m/10,000 ft. Failure to select the correct Altitude Adjustment setting, or diving above the maximum altitude limit will result in erroneous dive and planning data.
3. SUUNTO VYPER2 AT A GLANCE 3.1. Navigating in the menus Suunto Vyper2 has four main operating modes - TIME mode (TIME), DIVE mode (DIVE), PLAN mode (PLAN), and MEMORY mode (MEMORY) – as well as the COMPASS submode, which can be activated from either TIME or DIVE modes. To toggle between the main modes, press the MODE button. To select a submode in DIVE, PLAN and MEMORY modes, press the UP/DOWN buttons. 3.2.

4. GETTING STARTED WITH YOUR SUUNTO VYPER2 To get the most out of your Suunto Vyper2, take some time to personalize it and really make it YOUR computer. Set the correct time and date, as well as the alarms and tones, unit and backlight settings, then calibrate and test the compass function. Suunto Vyper2 is a very user-friendly dive computer, and you will quickly become familiar with its functions.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.4. Setting the units In the UNITS SETTING mode you can choose to have the units displayed in either the metric or imperial system - meters/feet, Celsius/Fahrenheit etc. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.5. Setting the backlight Use the BACKLIGHT SETTING mode to turn the backlight on or off and to define how long it stays on for (5, 10, 20, 30, or 60 seconds).
AC APPEARS IN THE TOP RIGHT CORNER OF THE DISPLAY, WHEN THE DIVE COMPUTER IS IN CONTACT WITH WATER. THIS ALSO ACTIVATES THE DIVE MODE. Contamination or dirt on the water contact may prevent this automatic activation. It is therefore 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. 4.3.
4.3.2. Locking a bearing A bearing can be locked to help you follow a selected course, and directional arrows point towards the locked bearing. Locked bearings are stored in the memory for later analysis and are available the next time the compass is activated. TO LOCK A BEARING, PRESS SELECT. The Suunto Vyper2 also provides help for navigating square and triangular patterns, as well as navigating a return heading.
Calibration Because of changes in the surrounding magnetic field, the Suunto Vyper2 electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field. As a basic rule, you should calibrate the compass whenever it doesn’t seem to operate properly, or after replacing the dive computer's battery. Strong electromagnetic fields, such as powerlines, stereo speakers, and magnets can affect the compass calibration.
5. BEFORE DIVING Do not attempt to use the dive computer without reading this user's manual 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 Suunto Vyper2 please contact your Suunto representative before diving with the dive computer.
5.4. Nitrox Diving with nitrox provides you with an opportunity to increase bottom times or reduce the risk of decompression illness by reducing the nitrogen content in the gas mix. However, when the gas mix is altered, the oxygen content of the mix is generally increased. This increase exposes the diver to an oxygen toxicity risk not usually considered in recreational diving.
Table 5.3. Oxygen alarms in NITROX mode Alarm type Alarm reason Continuous beeps for 3 minutes Set oxygen partial pressure limit is exceeded. The and activated backlight alternative display is replaced with a current blinking PO2 value. You should immediately ascend above the PO2 depth limit. OLF value reaches 80%. The OLF value will start to blink. OLF value reaches 100%. The OLF value will blink. NOTE When the backlight is turned OFF, it does not illuminate when an alarm is activated.
USE UP AND DOWN BUTTONS TO TOGGLE BETWEEN DIVE SETTINGS NOTE The settings cannot be activated until 5 minutes has elapsed after the dive. 5.7.1. Setting the depth alarm You can set a depth alarm in the dive computer. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. The depth alarm is factory-set to 30 m/131 ft, but you can adjust it according to your personal preference, or switch it off altogether. The depth range can be set from 3m to 100 m/9 ft to 328 ft. 5.7.2.
The default oxygen percentage (O2%) setting is 21% (air) and oxygen partial pressure (PO2) setting 1.4 bar. After entering values for MIX1, you can enable/disable and set an additional gas mix - MIX2. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. NOTE ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. If the oxygen content of a mix is set to 22% or above, the setting will remain stored until changed; it does not automatically revert back to 21%. 5.7.4.
5.7.7. Setting the RGBM values For certain divers and diving conditions, it may be desirable to set the attenuated RGBM mode. The selection is displayed during the DIVE mode startup. The options are full RGBM effects (100%), and attenuated RGBM (50%). ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8. Activation and pre-checks This section describes how to activate the DIVE mode and explains the pre-checks that it is highly recommended you perform before you get into the water. 5.8.1.
And, if set to NITROX mode, make sure that: • the correct number of mixes is set and that the oxygen percentages are adjusted according to the measured nitrox blends in your cylinders • the oxygen partial pressure limits are set correctly For more information on the NITROX mode, refer to Section 6.2. Diving in NITROX mode (DIVEnitrox). The dive computer is now ready for diving. 5.8.3. Battery power indication Temperature or internal oxidation of the battery affect the battery voltage.
5.8.5. 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. The three-step Personal Adjustment setting is available if a more conservative dive plan is desired and, for very experienced divers, a two step adjustment for RGBM effect on repetitive dives is available.
5.9. 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 Vyper2 displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.9.1.
WHEN CEILING AND STOP ARE DISPLAYED, 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. 5.10.
6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. You’ll find that this dive computer is easy to use and read. Each display shows only the data relevant to that specific diving mode. 6.1. Diving in AIR mode (DIVEair) In this section, we look at how to make the most of the dive computer when diving with standard air. To activate DIVEair mode, please see Section 5.8.1. Accessing DIVE mode.
UP BUTTON TOGGLES BETWEEN DIVE TIME AND WATER TEMPERATURE. 6.1.2. Bookmark It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display. The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software. The bookmark logs the depth, time, and water temperature, as well as compass heading (if the compass has been enabled).
If you exceed the no-decompression limits on a dive, the dive computer will provide the decompression information required for ascent. After this, the instrument will continue to provide subsequent interval and repetitive dive information. Rather than requiring you to make stops at fixed depths, the dive computer lets you decompress within a range of depths (continuous decompression). The ascent time (ASC TIME) is the minimum amount of time needed to reach the surface in a decompression dive.
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. Display below the floor The blinking ASC TIME 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.
DECOMPRESSION DIVE, ABOVE CEILING. NOTE DOWNWARD POINTING ARROW, ER WARNING AND ALARM. YOU SHOULD IMMEDIATLY (WITHIN 3 MINUTES) DES CEND TO OR BELOW CEILING. In addition, an Error warning (Er) reminds you that you have only three 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.
NITROX DIVE MODE ACTIVATION. MAXIMUM OPERATIONAL DEPTH BASED ON SET O2% (21%) AND PO 2 (1.4 BAR) IS 56.7 M. If set to NITROX mode, the Suunto Vyper2 will additionally show on the alternative display: • the oxygen percentage, labeled O2% • the set oxygen partial pressure limit, labeled PO2 • the current oxygen toxicity exposure, labeled OLF • maximum depth • current time • water temperature • dive time DOWN BUTTON TOGGLES BETWEEN O2, MAXIMUM DEPTH AND CURRENT TIME.
NOTE Mix number, O2%, 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. NOTE If no button is pressed in 15 seconds, the dive computer will go back to the dive display without changing the gas mix.
7. AFTER DIVING Once back at the surface, Suunto Vyper2 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 Do Not Fly Symbol 7.1. Surface interval An ascent to any depth shallower than 1.
7.4. Flying after diving The no-fly time is shown in the center window next to the airplane image. Flying or traveling to a higher altitude should be avoided at any time when the computer is counting down the no-fly time. The no-fly time is always at least 12 hours, or equivalent to the so-called desaturation time (if longer than 12 hours). For desaturation times lower than 70 minutes, no no-fly time is given. In the Permanent Error mode and GAUGE mode the no-fly time is 48 hours.
WHEN ENTERING THE MEMPLAN MODE THE DISPLAY FIRST BRIEFLY SHOWS TISSUE LOADING, THE REMAINING DESATURATION TIME BEFORE GOING INTO PLAN MODE. USE UP AND DOWN BUTTONS TO SCROLL DIFFERENT NO-DECOMPRESSION LIMITS. NO-DECOMPRESSION LIMITS LONGER THAN 99 MINUTES ARE DISPLAYED AS “–”.
PRESS UP OR DOWN BUTTONS TO DESCEND OR ASCEND. The mode can also be used to add the desired surface intervals for dive simulations. Add the desired surface interval increments to the present surface interval by pressing the UP and DOWN buttons. ADD SURFACE TIME IN 15 MINUTES INCREMENTS. 7.6. MEMORY mode The memory options include a dive logbook (MEMlogbook) and dive history (MEMhistory). The dive time and date are registered in the Logbook memory.
• date of dive • type of dive (Air, Nitrox, Gauge) • dive start time • dive number • oxygen percentage for Mix1 • total dive time Page II • maximum depth • surface time before previous dive • warnings Page III • depth/time profile of the dive • real-time water temperature The memory will retain approximately the last 42 hours of dive time. After that, when new dives are added, the oldest dives are deleted.

8. CARE AND MAINTENANCE The Suunto Vyper 2 dive computer is a sophisticated precision instrument. Though designed to withstand the rigors of scuba diving, you must handle your Suunto Vyper 2 with care, and follow the advice below on how to maximize its service life. 8.1. Water contacts and buttons Contamination or dirt on the water contacts/connector or buttons may prevent the automatic activation of the DIVE mode and cause problems during data transfer.
CAUTION • • • Do not use compressed air to blow water off the unit. Do not use solvents or other cleaning fluids that might cause damage. Do not test or use the dive computer in pressurized air. 8.4. Water resistance inspection The water resistance of the unit must be checked after replacing the battery or after other service operations. The check requires special equipment and training. You must frequently check the display for any sign of leaks.
Disassemble the shorter part of the strap with a fl at 1.5 mm screwdriver or a special tool for spring bars. The longer part of the strap may stay on but removing it may ease the work later on. Console model: • Remove the dive computer from the console according the instructions of the console. Thoroughly rinse and dry the computer. Open the securing ring of the battery compartment lid by pushing it down and rotating it clockwise.
Assemble the shorter part of the strap. Use the spring bar tool or small screwdriver to compress the spring bars. Make sure that the spring bars get fully seated so they will not come off their holes.
