  • Page 8 SELECT THE CORRECT ALTITUDE ADJUSTMENT SETTING! When WARNING 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.

    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.

  • Page 11: Getting Started With Your Suunto Vyper2

    BEFORE getting into the water. 4.1. TIME mode settings The first thing you'll want to do with your Suunto Vyper2, is to set the TIME mode shortcuts: alarm, time, date, units, backlight, and tones. In this section, we look at how to do this.

  • Page 12: Setting The Units

    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. 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).

  • Page 13: Learning How To Use Your Compass

    4.3. Learning how to use your compass Suunto Vyper2 integrates a digital compass, which can be used both while diving and on dry land, and can be accessed from either the DIVE mode or TIME mode.

  • Page 14: Locking A Bearing

    Locked bearings are stored in the memory for later analysis and are available the next time the compass is activated. The Suunto Vyper2 also provides help for navigating square and triangular patterns, as well as navigating a return heading. This is made possible by following graphical symbols in the center of the compass display: Table 4.1.
  • Page 15 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.

  • Page 16: Before Diving

    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.

  • Page 17: Nitrox

    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.

  • Page 18: Error Conditions

    5.7. DIVE mode settings Suunto Vyper2 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 sub-mode chosen (AIR, NITROX, GAUGE), so that, for example, nitrox settings are only available in the DIVENitrox sub-mode.

  • Page 19: Setting The Depth Alarm

    100 m/9 ft to 328 ft. 5.7.2. Setting the dive-time alarm The Suunto Vyper2 has a dive-time alarm setting which, when activated, can be used for several purposes to add to your diving safety. With a range of 1 - 999 minutes, the alarm can be set to your planned NOTE bottom time, for example.

    5.8.1. Accessing DIVE mode The Suunto Vyper2 has three diving modes: AIR mode for diving with standard air only, NITROX mode for diving with oxygen enriched mixtures, and GAUGE mode for use as a bottom timer.

  • Page 22: Battery Power Indication

    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 •...

  • Page 23: Personal Adjustments

    Several risk factors or conditions exist The Suunto Vyper2 also allows experienced divers who are willing to accept a greater level of risk to adjust the RGBM model. The default setting is 100%, which gives full RGBM effect. Suunto strongly advises you to use full RGBM effect. Statistically, very experienced divers have less incidents with DCI.

  • Page 24: Safety Stops

    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. Recommended Safety Stops With every dive over 10 meters, there is a three minute countdown for the Recommended Safety Stop, to be taken in the 6 - 3 m/10 ft - 20 ft range.

  • Page 25: Deep Stops

    Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation. The Suunto RGBM model calculates deep stops iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth. After the first Deep Stop is completed, another Deep Stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.

    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.

  • Page 27: Bookmark

    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).
  • Page 28 In such cases, it is more manageable to maintain an additional distance below the ceiling, to make sure that the waves do not lift you above the ceiling. Suunto recommends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
  • Page 29 NEVER ASCEND ABOVE THE CEILING! You must not ascend above WARNING 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.

  • Page 30: Diving In Nitrox Mode (Divenitrox)

    To set the nitrox mixes, refer to Section 5.7.3. Setting the nitrox values. Default nitrox settings In NITROX mode, the Suunto Vyper2 allows you to set 1 or 2 nitrox mixes containing 21- 99% oxygen. In the NITROX mode, the default setting for MIX1 is standard air (21% O ).

    7.3. Repetitive dive planning The Suunto Vyper2 includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual nitrogen loading of previous dives into consideration.

  • Page 34: Flying After Diving

    Following any dive that required a decompression stop, flying should be delayed for at least 24 hours, and if possible, for 48 hours Suunto recommends that flying is avoided until all the DAN and UHMS guidelines, as • well as the dive computer’s no-fly conditions, are satisfied 7.5.
