1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS

Suunto Vyper dive computer is designed to help you get the most out of your diving.
The Vyper dive computer is a compact and sophisticated multipurpose dive instrument

that will give you years of trouble-free and joyful diving.

The Suunto Vyper User's Guide contains vitally important information which enables
you to become familiar with your Suunto wristop dive computer. To understand the
use, displays, and limitations of the instrument before using it, please read this user's
guide carefully, and save it for further reference. Note also that a glossary is included
at the back of the user's guide to help you understand dive-specific terminology.

7

2. WARNINGS, CAUTIONS, AND NOTES

Throughout this user's guide, important safety icons are displayed. Three classifications
are used to separate these icons by their order of importance:

WARNING

is used in connection with a procedure or situation that may result
in serious injury or death

CAUTION

NOTE

Before you go on to read the user's guide itself, it is extremely important that you read
the following warnings. These warnings are intended to maximize your safety while
using Suunto Vyper and must not be ignored.

WARNING

WARNING

is used in connection with a procedure or situation that will result
in damage to the device

is used to emphasize important information

YOU MUST READ the leaflet and user guide for your dive com­puter. Failure to do so may lead to improper use, serious injury
or death.

ALLERGIC REACTIONS OR SKIN IRRITATIONS MAY OCCUR
WHEN PRODUCT IS IN CONTACT WITH SKIN, EVEN THOUGH
OUR PRODUCTS COMPLY WITH INDUSTRY STANDARDS.
IN SUCH EVENT, STOP USE IMMEDIATELY AND CONSULT
A DOCTOR.

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 illness (DCI).
Therefore, Suunto strongly recommends that the device not be
used for any commercial or professional diving activities.

WARNING

WARNING

ONLY DIVERS TRAINED IN PROPER USE OF SCUBA DIVING
EQUIPMENT SHOULD USE A DIVE COMPUTER! No dive
computer can replace the need for proper dive training. Insufficient
or improper training may cause a diver to commit errors that may
lead to serious injury or death.

THERE IS ALWAYS A RISK OF DECOMPRESSION ILLNESS
(DCI) FOR ANY DIVE PROFILE EVEN IF YOU FOLLOW THE
DIVE PLAN PRESCRIBED BY DIVE TABLES OR A DIVE
COMPUTER. NO PROCEDURE, DIVE COMPUTER OR DIVE
TABLEWILL PREVENT THE POSSIBILITY OF DCI OR OXYGEN
TOXICITY! An individual’s physiological make up can vary from
day to day. The dive computer cannot account for these variations.
You are strongly advised to remain well within the exposure limits
provided by the instrument to minimize the risk of DCI. As an
added measure of safety, you should consult a physician regarding
your fitness before diving.

9

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 PO2OF 1.4 BAR! Exposure
to greater depths increases the risk of oxygen toxicity and decom­pression illness.

10

WARNING

WARNING

WARNING

DIVES WITH REQUIRED 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.

USE BACK-UP INSTRUMENTS! Ensure 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.

PERFORM PRE-CHECKS! Always activate and check the device
before diving in order to ensure that all Liquid Crystal Display
(LCD) segments are completely displayed, the device has not
run out of battery power, and that the oxygen, altitude, personal,
and Safety/Deep Stop are correct.

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 DCI. Review
the recommendations given by Divers Alert Network (DAN). There
can never be a flying after diving rule that is guaranteed to com­pletely prevent decompression illness!

WARNING

THE DIVE COMPUTER SHOULD NEVER BE TRADED OR
SHARED BETWEEN USERS WHILE IT IS IN OPERATION! Its
information will not apply to someone who has not been wearing
it throughout a dive or sequence of repetitive dives. Its dive profiles
must match that of the user. If it is left on the surface during any
dive, the dive computer will give inaccurate information for sub­sequent dives. No dive computer can take into account dives
made without the computer. Thus, any diving activity up to four
days prior to initial use of the computer may cause misleading
information and must be avoided.

11

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. If there is a desire to adjust the computer to
provide more conservative calculations, use the personal adjust­ment feature to affect decompression calculations or reduce the
PO2setting to affect oxygen exposure according to the entered
O2% and PO2values.

12

WARNING

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 the decompression status. The dive computer is not
intended for use at altitudes greater than 3000 m/10000 ft. Failure
to select the correct Altitude Adjustment setting or diving above
the maximum altitude limit will result in erroneous dive and plan­ning data.

WARNING

SET THE CORRECT PERSONAL ADJUSTMENT MODE!
Whenever it is believed that factors that tend to increase the
possibility of DCI 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

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).

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
These factors will also increase the amount of air required to

reach the surface.

13

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.

14

WARNING

WARNING

WARNING

DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU
HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND
ENTERED THE ANALYSIS 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.

DO NOT DIVE WITH A GAS 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 gas values where applicable
into your dive computer will result in incorrect dive planning inform­ation.

Diving with gas mixtures exposes you to risks that are different
from those associated with diving with standard air. These risks
are not obvious, and require training to understand and avoid.
Risks include possible serious injury or death.

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

WARNING

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

Suunto also recommends that you receive training in Free diving
techniques and physiology before conducting breath hold dives.
No dive computer can replace the need for proper dive training.
Insufficient or improper training may cause a diver to commit errors
that may lead to serious injury or death.

Using the Suunto Dive Planner software is not a substitute for
proper dive training. Diving with mixed gases has dangers that
are not familiar to divers diving with air. To dive with trimix, triox,
heliox and nitrox or all of them, divers must have specialized
training for the type of diving they are doing.

15

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

NOTE

In GAUGE mode the no-fly time is always 48 hours.

16

ENSURE THE WATER RESISTANCEOF THE DEVICE! Moisture
inside the device or battery compartment will seriously damage
the unit. Only an authorized SUUNTO dealer or distributor should
do service activities.

It is not possible to change between AIR, NITROX and GAUGE
modes before the instrument has counted down the no-fly time.
There is one exception to this: You can change from AIR to NI­TROX mode even during the no-fly time.

3. SUUNTO USER INTERFACE

3.1. Navigating in the menus

Suunto Vyper multipurpose dive computer features three dive computer modes (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. You can scroll through the modes using the push buttons.
The mode indicator at the left side and the mode text at the bottom of the display in­dicate the selected mode.

The timekeeping display is the primary display of the instrument. In other modes (except
in the Diving or Simulator modes), if no button is operated within 5 minutes, the dive
computer beeps and returns to the timekeeping display automatically. The timekeeping
display shuts off after two hours, but pressing the PLAN or TIME button activates it.

When diving, the dive entry time and date is registered in the Logbook Memory. Re­member always to check before diving that the time and date are correctly set, espe­cially when traveling to different time zones.
