1. WELCOME TO THE WORLD OF SUUNTO DIVING INSTRUMENTS AIR Suunto Vyper 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 AT A GLANCE 3.1. Navigating in the menus AIR Suunto Vyper 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.

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.
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 AIR Vyper , 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.
Alarm type Alarm reason Continuous beep series for 24 seconds or until any button is pressed. Current time blinks for one minute Preset alarm time is reached. 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%.
In order to use the transmitter, the wireless integration needs to be enabled in your Suunto AIR Vyper 's settings. To enable or disable the wireless integration refer to Section 5.8.10. Setting the tank pressure. 5.7.1. Installing the wireless transmitter AIR When purchasing the Suunto Vyper , 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.
In order to save battery energy, the transmitter shuts off if the pressure remains unchanged for more than 5 minutes, and it will continue transmitting with the saved code when any pressure change is measured. NOTE 5.7.3. Transmitting data AIR After the pairing procedure, the Suunto Vyper will receive cylinder pressure data from the transmitter. The pressure is displayed in either bars or psi, depending on the unit AIR selected.
NOTE Some settings cannot be changed until 5 minutes has elapsed after the dive. 5.8.1. 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/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 100 m/9 ft to 328 ft. 5.8.2.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. NOTE ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. If MIX2 is set ON, settings for all mixes are stored until changed.

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. 5.9.1. Accessing DIVE mode AIR The Suunto Vyper 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 and for freediving.
the pressure transmitter is working (wireless transmitter indicator blinks, cylinder pressure is displayed), and that there is no low battery warning displayed • you have enough air for your planned dive.
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 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.
Table 5.7. RGBM model settings RGBM setting Desired Tables Effect 100% Standard Suunto RGBM model Full RGBM effects (Default) 50% Attenuated RGBM model Smaller RGBM effects, higher risk! 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.
You must not ascend shallower than 3 m/10 ft with the Mandatory Safety Stop warning on. If you ascend above the Mandatory Safety Stop ceiling, a downward pointing arrow will appear and a continuous beeping starts.You should immediately descend to, or below, the Mandatory Safety Stop ceiling depth. If you correct this situation at any time during the dive, there are no effects on the decompression calculations for future dives.
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 5.9.1. Accessing DIVE mode.
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 • 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. 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.
NOTE Filling your BC affects the air time calculation due to the temporary increase in air consumption. NOTE A change of temperature will affect the cylinder pressure and consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/725 psi.
• • • the time needed at the ceiling the time needed at the Mandatory Safety Stop (if any) the time needed to reach the surface after the mandatory decompression dives have been completed NOTE In addition, there may also be Mandatory Safety Stops which are not displayed in ASC TIME.
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. 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 MANDATORY SAFETY STOP IS 15 MINUTES.
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. You must not dive again for at least 48 hours. (See Section 5.6. Error conditions). 6.2. Diving in NITROX mode (DIVEnitrox) NITROX mode (DIVEnitrox) is the second dive mode available in Suunto Vyper is used when using oxygen-enriched gas mixtures. AIR and 6.2.1.
• • • • • maximum depth current time water temperature dive time tank pressure DOWN BUTTON TOGGLES BETWEEN O2, MAXIMUM DEPTH TANK PRESSURE AND CURRENT TIME. UP BUTTON TOGGLES BETWEEN PO2, OLF, DIVE TIME AND WATER TEMPERATURE. 6.2.3. Oxygen limit fraction (OLF) If set to 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.
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 an audible 3 beeps and the current O2 mix starts to blink. 6.3. Diving in GAUGE mode (DIVEgauge) If set to GAUGE mode, the dive computer can be used as a bottom timer.
7. AFTER DIVING AIR Once back at the surface, Suunto Vyper continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety. Table 7.1.
