Before you dive
Make sure that you fully understand the use, displays and limitations of your dive instruments.
If you have any questions about this manual or dive computer, contact your Suunto dealer
before diving. Always remember that YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY!
This dive computer is intended for use with compressed air only.
Safety precautions
WARNING: ONLY TRAINED DIVERS SHOULD USE A DIVE COMPUTER! Insucient
training for any kind of diving, including freediving, may cause a diver to commit errors, such
as incorrect use of gas mixtures or improper decompression, that may lead to serious injury
or death.
WARNING: You must read the printed quick guide and online user guide for your dive
computer. Failure to do so may lead to improper use, serious injury or death.
WARNING: THERE IS ALWAYS A RISK OF DECOMPRESSION SICKNESS (DCS) 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 TABLE WILL PREVENT THE
POSSIBILITY OF DCS OR OXYGEN TOXICITY! An individual’s physiological makeup 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 DCS. As an added measure of safety, you should consult a physician regarding your
fitness before diving.
WARNING: If you have a pacemaker, we recommend you do not scuba dive. Scuba
diving creates physical stresses on the body which may not be suitable for pacemakers.
WARNING: If you have a pacemaker, consult a doctor before using this device. The
inductive frequency used by the device may interfere with pacemakers.

WARNING: 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 sickness (DCS). Therefore,
Suunto strongly recommends that the device not be used for any commercial or professional
diving activities.
WARNING: USE BACKUP INSTRUMENTS! Ensure that you use backup instrumentation,
including a depth gauge, submersible pressure gauge, timer or watch, and have access to
decompression tables whenever diving with a dive computer.
WARNING: For safety reasons, you should never dive alone. Dive with a designated
buddy. You should also stay with others for an extended time after a dive as the onset of
possible DCS may be delayed or triggered by surface activities.
WARNING: PERFORM PRE-CHECKS! Always check that your dive computer is functioning
properly and has the correct settings before diving. Check that the display is working, the
battery level is OK, tank pressure is correct, and so forth.
WARNING: Check your dive computer regularly during a dive. If you believe or conclude
that there is any problem with any computer function, abort the dive immediately and safely
return to the surface. Call Suunto Customer Support and return your computer to an
authorized Suunto Service Center for inspection.
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.
WARNING: DO NOT EXPOSE ANY PART OF YOUR DIVE COMPUTER TO ANY GAS MIX
CONTAINING MORE THAN 40% OXYGEN! Enriched air with greater oxygen content presents
a risk of fire or explosion and serious injury or death.
WARNING: 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 tank contents and enter the appropriate gas values where applicable into your dive
computer will result in incorrect dive planning information.
WARNING: Using a dive planner software such as in Suunto DM5 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.

A bearing is the angle between north and your target. In simple terms, it is the direction you
want to travel. Your heading, on the other hand, is your actual direction of travel.
The default bearing is North.
You can set a bearing lock to help you orientate yourself underwater and ensure you maintain
your direction of travel. For example, you can set a bearing lock for the direction to a reef
before leaving the boat.
The last locked bearing is stored and available the next time the compass is activated. In
DIVE mode, the locked bearings are also stored in the log. To lock a bearing:

3.10. Decompression dives
If you exceed the no-decompression limit on a dive, when NO DEC TIME reaches zero, your
dive changes into a decompression dive. Therefore, you must perform one or more
decompression stops on your way to the surface.
When the decompression dive starts, the NO DEC TIME on your display is replaced by ASCTIME, and a CEILING indicator appears. An upward pointing arrow also prompts you to start
your ascent.
Suunto Vyper Novo provides the decompression information required for ascent with two key
values:
•
CEILING: depth that you should not go above
•
ASC TIME: optimum ascent time in minutes to surface with
If you exceed the no-decompression limits on a dive, the dive computer provides the
decompression information required for ascent along with subsequent details that are
updated as you ascend.

Ceiling, ceiling zone, floor and decompression range
Before you do a decompression dive, you need to understand the meaning of ceiling, ceiling
zone, floor, and decompression range. You need to understand these concepts to be able to
correctly interpret the guidance provided by the dive computer.
•
The ceiling is the shallowest depth to which you should ascend when doing
decompression.
•
The ceiling zone is the optimum decompression depth range. It is the range between the
ceiling depth and 1.2 m (4 ft) below that ceiling.
•
•
The depth of the ceiling and floor depends on your dive profile. The ceiling depth is fairly
shallow when you first enter the decompression dive. But if you remain at depth, the ceiling
depth moves downward, and the ascent time increases. The opposite is also true: the floor
and ceiling depths may change upwards while you are decompressing.
floor is the deepest depth at which the decompression stop time does not increase.
The
Decompression starts when you pass this depth during your ascent.
The decompression range is the depth range between the ceiling and

When conditions are rough, it may be
In such cases, it is more manageable to maintain a depth somewhat below the ceiling, to
ensure that the waves do not lift you above the ceiling. Suunto recommends that you
decompress deeper than 4 m (13 ft), even if the indicated ceiling is shallower.
dicult to maintain a constant depth near the surface.
Ascent time
The ascent time shown on your dive computer is the minimum amount of time needed to
reach the surface on a decompression dive. This includes:
•
Time required to do deepstops
•
Ascent time from depth at an ascent rate of 10 m (32.8 ft) per minute
19
Page 20
Suunto Vyper Novo
•
Time needed for decompression
•
Time needed for extra safety stops if ascending too fast during the dive
WARNING: Your actual ascent time may be longer than displayed by Suunto Vyper Novo.
It may be longer if your ascending speed is slower than 10 m (32.8 ft) per minute or you are
doing a decompression stop deeper than the recommended ceiling. Take this into account,
since it might increase the amount of required breathing gas to reach the surface.
Decompression guidance
On a decompression dive, there can be three kinds of stops:
•
Safety stop
•
Deepstop
•
Decompression stop
Though not recommended, you may break (ignore) deepstops and safety stops. Suunto Vyper
Novo penalizes such actions with additional stops or other measures, either during the dive or
on following dives. For more information, see 3.21. Safety stops and deepstops.
Suunto Vyper Novo shows the ceiling value always from the deepest of these stops.
Deepstop and safety stop ceilings are always at constant depth when you are at the stop.
Stop time is counted down in minutes and seconds.
With decompression stops, the ceiling is always decreasing while you are near the ceiling
depth, providing continuous decompression with optimum ascent time.
NOTE: It is always recommended to keep close to the decompression ceiling when
ascending.
Below the floor
The blinking ASC TIME text and an upward arrow indicate that you are below the floor. A low
priority alarm will also sound. You should start your ascent immediately. The ceiling depth is
shown on the left side of the center
Below is an example of a decompression dive with a ceiling of 3 m and total ascent time of 9
minutes.
field, and the minimum total ascent time on the right side.
Above the floor
When you ascend above the floor, the ASC TIME text stops blinking and the upward arrow
disappears, as shown below.
This indicates you are in the decompression range. Decompression begins, but slowly.
Therefore, you should continue your ascent.
20
Page 21
Suunto Vyper Novo
At the ceiling
When you reach the ceiling zone, the display will show you two arrows pointing at each other
as shown below.
During the decompression stop, your total ascent time continues to count down towards zero.
If the ceiling moves upwards, you can ascend to the new ceiling.
You may surface only after ASC TIME and CEILING have disappeared. This means that the
decompression stop and any mandatory safety stop have been completed.
You are advised, however, to stay below the ceiling until the STOP text has also disappeared.
This indicates that the three (3) minute recommended safety stop has also been completed.
Above the ceiling
If you ascend above the ceiling during a decompression stop, a downward arrow appears in
from of the ceiling depth, and a continuous beeping starts.
In addition, an error warning ER reminds you that you have only three (3) minutes to correct
the situation. You must immediately descend to, or below, the ceiling. If you continue to
violate the decompression, the dive computer goes into a permanent error mode (3.18. Errorstate (algorithm lock)).

confirm.
3.18. Error state (algorithm lock)
Suunto Vyper Novo has warning indicators that alert you to react to certain situations that
would significantly increase the risk of DCI. If you do not respond to these warnings, Suunto
Vyper Novo enters an error state and shows Er on the display. This indicates that the risk of
DCI has greatly increased.
28
Page 29
Suunto Vyper Novo
If you omit decompression stops for longer than three (3) minutes, the RGBM algorithm is
locked for 48 hours. When the algorithm is locked, no algorithm information is available and
ER is shown instead. Locking the algorithm is a safety feature, highlighting that the algorithm
information is no longer valid.
In such a condition, you should descend back below the ceiling level to continue the
decompression. If you fail to do so within three (3) minutes, Suunto Vyper Novo locks the
algorithm calculation and displays ER instead, as shown below. Note that the ceiling value is
no longer present.
In this state, you
significantly increase your risk of decompression sickness (DCS).
Decompression information is not available for the next 48 hours after surfacing.
It is possible to dive with the device when the algorithm is locked, but instead of the
decompression information, ER is shown.

the display back on, press any button.
3.21. Safety stops and deepstops
Safety stops are widely considered good diving practice and are a critical 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.
Suunto Vyper Novo displays two dierent types of safety stops: recommended and
mandatory.
With every dive over 10 meters (30 feet), there is a three-minute countdown for the
recommended safety stop. This stop is taken in the 3-6 m (10-20 ft) range. Suunto Vyper Novo
shows a STOP icon and a three-minute countdown.
NOTE: When deepstops are enabled, the length of mandatory safety stops is indicated
in seconds.
When the ascent rate exceeds 10 m (33 ft) per minute for more than five consecutive seconds,
the microbubble build-up may be more than is allowed for in the decompression model.
In this situation, Suunto Vyper Novo adds a mandatory safety stop to the dive. The time of this
stop depends on the speed violation of the ascent rate.
The STOP icon is shown in the display. When you reach the depth zone between 6 m and 3 m
(18 ft and 9 ft) the following is displayed:

The Divers Alert Network (DAN) recommends the following on no-fly times:
•
A minimum surface interval of 12 hours would be required in order to be reasonably
assured a diver will remain symptom free upon ascent to altitude in a commercial jetliner
(altitude up to 2,400 m (8,000 ft)).
•
Divers who plan to make daily, multiple dives for several days, or make dives that require
decompression stops, should take special precautions and wait for an extended interval
beyond 12 hours before a flight. Further, the Undersea and Hyperbaric Medical Society
(UHMS) suggests divers using standard air cylinders and exhibiting no symptoms of
decompression sickness wait 24 hours after their last dive to fly in an aircraft with cabin
pressure up to 2,400 m (8,000 ft). The only two exceptions to this recommendation are:
•
If a diver has less than two (2) hours total accumulated dive time in the last 48 hours, a
12 hour surface interval before

Following any dive that required a decompression stop, flying should be delayed for at
least 24 hours, and if possible, for 48 hours.

3.26. Suunto RGBM
Suunto's decompression model development originates from the 1980s when Suunto
implemented Bühlmann's model based on M-values in Suunto SME. Since then research and
development has been ongoing with the help of both external and internal experts.
In the late 1990s, Suunto implemented Dr. Bruce Wienke's RGBM (Reduced Gradient Bubble
Model) bubble model to work with the earlier M-value based model. The first commercial
products with the feature were the iconic Suunto Vyper and Suunto Stinger. With these
products the improvement of diver safety was
diving circumstances outside the range of dissolved-gas-only models by:
•
Monitoring continuous multiday diving
•
Computing closely spaced repetitive diving
•
Reacting to a dive deeper than the previous dive
•
Adapting to rapid ascents which produce high microbubble (silent-bubble) build-up
•
Incorporating consistency with real physical laws for gas kinetics
The Suunto RGBM predicts both dissolved and free gas in the blood and tissues of divers. It is
significant advancement on the classic Haldane models, which do not predict free gas. The

profiles.
significant as they addressed a number of
3.26.1. Diver Safety
Because any decompression model is purely theoretical and does not monitor the actual
body of a diver, no decompression model can guarantee the absence of DCS. Experimentally
it has been shown that the body adapts to decompression to some degree when diving is
constant and frequent. Personal adjustment settings are available for divers who dive
constantly and are ready to accept greater personal risk.
CAUTION: Always use the same personal and altitude adjustment settings for the actual
dive and for the planning. Increasing the personal adjustment setting from the planned
setting as well as increasing the altitude adjustment setting can lead to longer
decompression times deeper and thus to larger required gas volume. You can run out of
breathing gas underwater if the personal adjustment setting has been changed after dive
planning.
3.26.2. Altitude diving
The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a
higher altitude, you will have additional nitrogen in your body, compared to the equilibrium
situation at the original altitude. This 'additional' nitrogen is released gradually over time and
equilibrium is restored. It is recommended that you acclimatize to a new altitude by waiting at
least three hours before making a dive.
Before high-altitude diving, you need to adjust the altitude settings of your dive computer so
that the calculations take into account the high altitude. The maximum partial pressures of
nitrogen allowed by the mathematical model of the dive computer are reduced according to
the lower ambient pressure.
As a result, the allowed no decompression stop limits are considerably reduced.
34
Page 35
Suunto Vyper Novo
WARNING: SET THE CORRECT ALTITUDE SETTING! When diving at altitudes greater
than 300 m (1000 ft), the altitude setting 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 setting or diving above
the maximum altitude limit will result in erroneous dive and planning data.
3.26.3. Oxygen exposure
The oxygen exposure calculations are based on currently accepted exposure time limit tables
and principles.
The dive computer calculates separately the Central Nervous System oxygen toxicity (CNS)
and the Pulmonary Oxygen toxicity, the latter measured by the addition of Oxygen Toxicity
Units (OTU).
Both fractions are scaled so that the diver’s maximum tolerated exposure for each is 100%.
Suunto Vyper Novo does not display CNS% or OTU% but instead displays the larger of the
two in the OLF%
For example, if the diver’s maximum tolerated exposure for CNS% is 85% and the maximum

field.OLF% value is the Oxygen limit fraction or Oxygen Toxicity Exposure.
Oxygen related information displayed by the dive computer is also designed to ensure that all
warnings and displays occur at the appropriate phases of a dive.
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 a CNS/OTU warning is
given can rapidly increase the risk of oxygen toxicity, injury, or death.
3.27. Tank pressure
When using the optional Suunto Wireless Transmitter, the pressure of your tank is shown in
the lower left of the display.
Whenever you start a dive, the remaining air time calculation begins. After 30-60 seconds, the
first estimation of remaining air time is shown in the left center of the display.
The calculation is always based on the actual pressure drop in your tank and automatically
adapts to your tank size and current air consumption.
The change in your air consumption is based on constant one second interval pressure
measurements over periods of 30–60 seconds. An increase in air consumption decreases the
remaining air time rapidly, while a drop in air consumption increases the air time slowly. In this
way, an overly optimistic air time estimate, caused by a temporary drop in air consumption, is
avoided.
The remaining air time calculation includes a 35 bar (500 psi) safety reserve. This means that
when the instrument shows the air time to be zero, there is still a small reserve.

air consumption.

first stage of your regulator.
In order to receive wireless data, the transmitter and the Suunto Vyper Novo need to be
paired.
The wireless transmitter activates when the tank pressure exceeds 15 bar (300 psi). The
transmitter then starts sending pressure data together with a code number.
When your Suunto Vyper Novo is within 0.3 m (1 ft) of the transmitter, it receives and stores
that code. The transmitter and Suunto Vyper Novo are now paired. Suunto Vyper Novo will
then display the pressure data it receives with this code. This coding procedure prevents data
mix-up from other divers also using a Suunto Wireless Transmitter.
NOTE: The pairing procedure normally only needs to be done once. You may need to
redo the pairing procedure if another diver in your group uses the same code.
To assign a new transmitter code:
1.Slowly open the tank valve fully to pressurize the system.
2. Immediately close the tank valve.
36
Page 37
Suunto Vyper Novo
3. Quickly depressurize the regulator so that the pressure is reduced to less than 10 bar (145
psi).
4. Wait about 10 seconds, and slowly open the tank valve again to re-pressurize above 15 bar
(300 psi).
The transmitter assigns a new code automatically. To re-pair the transmitter with your Suunto
Vyper Novo:
1.While in a dive mode other than Free or Gauge, keep [DOWN] pressed to enter the
settings.
2. Press [DOWN] to scroll to Tank Press Pairing and press SELECT.
3. Make sure TANK PRESS PAIRING is set to ON and press [SELECT] .
4. A code number is displayed. Press [UP] to clear the code.
5. Press [SELECT] .
6. Press [MODE] to exit.
With the system pressurized to above 15 bar (300 psi), bring your Suunto Vyper Novo close to
the transmitter. When pairing is completed, the dive computer displays the new code number
and the transmitted tank pressure.
The wireless transmitter indicator is displayed every time a valid signal is received.
3.27.3. Transmitted data
After pairing, your Suunto Vyper Novo receives tank pressure data from the transmitter.
Any time the Suunto Vyper Novo receives a signal, one of the following symbols is shown in
the lower left corner of the display.

3.29. Water contact
The water contact is located on the side of the case. When submerged, the water contact
poles are connected by the conductivity of the water. Suunto Vyper Novo switches to dive
state when water is detected and the depth gauge senses water pressure at 1.2 m (4 ft).
The AC is shown until the water contact deactivates. It is important to keep the water contact
area clean. Contamination or dirt can prevent automatic activation/deactivation.
38
