This dive computer is a compact and sophisticated multipurpose dive instrument that will give you years of trouble-free and joyful diving. 1.1. SAFETY PRECAUTIONS Do not attempt to use the dive computer without reading this instruction manual in its entirety, including all the warnings below.
NO PROCEDURE, DIVE COMPUTER OR DIVE TABLE WILL PRE- VENT THE POSSIBILITY OF DECOMPRESSION SICKNESS (DCS) OR OXYGEN TOXICITY! You must understand and accept that there is no pro- cedure, dive computer or dive table that will totally prevent the possibility of a decompression accident or that oxygen toxicity will not occur, even within accepted limits.
ENSURE THE WATER RESISTANCE OF THE DEVICE! Always check the water resistance of the battery compartment when replacing the battery. Moisture inside the device or battery compartment will seriously damage the unit. Only an authorized SUUNTO dealer or distributor should do service activities. 1.1.1. Emergency Ascents In the unlikely event that the dive computer malfunctions during a dive, follow the emergency procedures provided by your certiﬁ...
1.1.2. Dive Computer Limitations While the dive computer is based on current decompression research and technol- ogy, you must realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including the U.S. Navy Tables, are based on a theoretical math- ematical models, which are intended to serve as a guide to reduce the probability of decompression sickness.
2. GETTING ACQUAINTED 2.1. FUNCTIONS The VYPER multipurpose dive computer features three dive computer models (AIR, NITROX, GAUGE), three main operating modes (TIME/STAND-BY, SURFACE, DIVING), three menu based main modes (MEMORY, SIMULATION, SET) and 15 - 17 menu based submodes (see ﬁ gure in the back cover). You can scroll through the modes using the push buttons.

WATER CONTACTS The water contacts control the automatic activation of the Dive Mode. The water and data transfer contacts are located on bottom of the case (Fig 2.3).
3. DIVING WITH THE DIVE COMPUTER This section contains instructions on how to operate the dive computer and interpret its displays. You will ﬁ nd that this dive computer is easy to use and read. Each display shows only the data relevant to that speciﬁ...
Fig. 3.3 Startup III. The Gauge Mode. ° DIVE TIME Fig 3.4 Startup IV. The Surface Mode: The depth and dive time are zeros (as no dives have yet been made), and the tempera- ture is 20°C [68°F]. ° DIVE TIME Fig.
3.1.2. Battery Power Indicator and Low Battery Warning This dive computer has a unique graphic Battery Power Indicator designed to give you an advance notice of impending need to change the battery. The Battery Power Indicator can always be seen, when the Dive Mode is acti- vated.
3.1.3. Dive Planning [PLAN] It is possible at any time in the Surface Mode to enter the Planning Mode, simply by pressing the PLAN button. After showing the text PLAN (Fig. 3.6), the display will show the no-decompression limit for the depth of 9 m [30 ft]. By pressing the arrow down TIME (t) button, the dive computer will calculate and show the next deeper no-decompression limits in 3 m [10 ft] increments ending at 45 m [150 ft].
3.1.4. User Deﬁ nable Functions and Alarms This dive computer has several User Deﬁ nable Func- tions and depth and time related alarms to be preset according to your personal preference. The dive computer model, units and backlight on time preferences can be set in the MODE- SET- SET PREF submode.
200 minutes, the ﬁ rst (lowest) bar graph segment appears. As your body absorbs more nitrogen, more segments start to appear. Green Zone - As a safety precaution SUUNTO recommends that when using this dive computer you should maintain the no-decompression bar graph within the green zone.
3 m - 6 m [10 ft - 20 ft]. RECOMMENDED SAFETY STOP SUUNTO highly recommends a safety stop at the end of every dive in the range of 3 m - 6 m [10 ft - 20 ft] for at least 3 minutes. This is shown with...
The Mandatory Safety Stop time always includes the three-minute Recom- mended Safety Stop time. The total length of the Mandatory Safety Stop time depends on the seriousness of the ascent rate violation. You must not ascend shallower than 3 m [10 ft] with the Mandatory Safety Stop warning on.
STOP NO DEC TIME ° DIVE TIME Fig. 3.13 Ascent Rate Indicator. Blinking depth reading, SLOW and four segments shown: ascent rate is more than 10 m/min [33 ft/min]. This is a caution to slow down! The STOP sign means that you are advised to make a Manda- tory Safety Stop when you reach the depth of 6 m [20 ft].
3.2.5. Decompression dives When your NO DEC TIME becomes zero, your dive becomes a decompression dive, i.e. you must perform one or several decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME notation and the maximum depth will be replaced by a CEILING notation and an upward pointing arrow (Fig.
YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY WHEN THE DIVE COMPUTER SHOWS YOU THAT DECOMPRESSION IS REQUIRED! Note the blinking ASC TIME symbol and the upward pointing arrow. 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/min [33 ft/min] or - make your decompression stop deeper than at the ceiling.
SUUNTO recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower.
CEILING STOP ASC TIME ° DIVE TIME Fig. 3.18 Decompression dive, at the ceiling zone. The two ar- rows point at each other (“hour glass”). You are at the optimum ceiling zone at 3.5 m [11 ft] and your minimum ascent time is 5 minutes.
3.3. DIVING WITH ENRICHED AIR NITROX 3.3.1. Before Diving This dive computer can be used for diving with standard air only (AIR Mode) or it can be set for diving with Enriched Air Nitrox (EANx) (NITROX Mode). If you are educated for nitrox diving and you plan to make nitrox dives, it is recom- mended that you set the dive computer permanently to its NITROX Mode (see chapter 4.3.

3.4. GAUGE MODE If set to GAUGE Mode, the dive computer can be used for diving with TRIMIX or other technical div- ing gas mixes. If you are educated for technical diving and you plan to make these kind of dives, it is recom- mended that you set the instrument permanently to its GAUGE Mode (see chapter 4.3.
° DIVE TIME Fig. 3.27 Surface display. You have surfaced from a 18 minute dive, which maximum depth was 20.0 m [66 ft]. The present depth is 0.0 m [0 ft]. The airplane symbol indicates that you should not ﬂ y and the dive attention symbol indicates that you should prolong your surface interval time.
If set to NITROX Mode, the following information will also be shown: • the oxygen percentage labeled with O is shown on the left side of the center win- • the current oxygen toxicity exposure shown with an Oxygen Limit Fraction (OLF) bar graph along the left side of the display (instead of the CBT).
- Following any dive that required a decompression stop, ﬂ ying should be delayed for at least 24 hours, and if possible, for 48 hours. SUUNTO recommends that ﬂ ying is avoided until all the DAN and UHMS guidelines and the dive computer wait to ﬂ y conditions are satisﬁ ed.
3.6. AUDIBLE AND VISUAL ALARMS The dive computer features audible and visual alarms to advise when important limits are ap- proached or to acknowledge preset alarms. A short single beep occurs, when: • the dive computer is activated • when the dive computer automatically returns to the TIME Mode.
You are able to set alarms before the actual dive. The preset user programmable alarms can be set for time, dive time and maximum depth. The alarms activate when: • The preset alarm time is reached (Fig. 3.31) - the current time is shown - continuous beep series for 24 seconds or until any button is pressed - the current time blinks for one minute, if no button is pressed.
The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1 = one mountain, or A2 = two mountains). Section 126.96.36.199. “Altitude Adjustment and Personal Adjustment Setting” describes how the Altitude Mode is adjusted. SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When diving at altitudes greater than 300 m [1000 ft] the Altitude Adjustment feature must be correctly selected in order for the computer to calculate no-decompression status.
The Personal Adjustment Mode is indicated by a diver symbol and plus signs (P0 = a diver, P1 = diver +, or P2 = diver ++). Section 188.8.131.52. “Altitude Adjustment and Personal Adjustment Setting” describes how the Personal Mode is adjusted. This feature should be used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment Mode with the help of Table 3.4.
3.8. ERROR CONDITIONS The dive computer has warning indicators that alert the user to react to certain situations that would otherwise give rise to a signiﬁ cantly increased risk of DCS if left unattended. If you do not respond to its warnings, the dive computer will enter an Error Mode, indicating that the risk of DCS has greatly increased.

6. TECHNICAL DESCRIPTION 6.1. OPERATING PRINCIPLES NO-DECOMPRESSION LIMITS The no-decompression limits displayed by the dive computer in a fresh start are (see Table 6.1 and Table 6.2), for most dives to a single depth, slightly more con- servative than those permitted by the U.S. Navy tables. TABLE 6.1 NO-DECOMPRESSION TIME LIMITS (min) FOR VARIOUS DEPTHS (m) FOR THE FIRST DIVE OF A SERIES Personal Mode / Altitude Mode...
ALTITUDE DIVING The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a higher altitude, the diver will have additional nitrogen in his body, compared to the equilibrium situation at the original altitude. This “additional” nitrogen is released gradually in time and equilibrium is reached within a couple of days.
• taking a modern approach to a difﬁ cult problem. The SUUNTO RGBM algorithm is developed in co-operation with SUUNTO and Bruce R. Wienke. It is based both on laboratory experiments and diving data (for example DAN’s dive data).
6.3. 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. These include for example: • the displayed oxygen exposure calculations are rounded to the next higher whole percentage value •...
