Safety precautions
WARNING: ONLY TRAINED DIVERS SHOULD USE A DIVE
COMPUTER! Insufficient 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 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 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.
6
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.
7
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
there is any apparent malfunction, abort the dive immediately and
safely return to the surface.
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.
8
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.
WARNING: Do not use Suunto USB Cable in areas where
flammable gases are present. Doing so may cause an explosion.
WARNING: Do not disassemble or remodel Suunto USB Cable in
any way. Doing so may cause an electric shock or fire.
WARNING: Do not use Suunto USB cable if cable or parts are
damaged.
CAUTION: DO NOT allow the connector pins of the USB cable to
touch any conductive surface. This may short circuit the cable,
making it unusable.

3.12 Dive numbering
If the Suunto Zoop Novo has not counted the no-fly time down to
zero, then repetitive dives belong to the same dive series.
Within each series, the dives are given numbers. The first dive of the
series is DIVE 1, the second DIVE 2, and so on.
If you start a new dive with less than five (5) minutes at the surface,
Suunto Zoop Novo treats the new dive as part of the previous dive.
The dive time continues where it left off.
After five (5) minutes or more at the surface, any new dives are part
of a repetitive dive series. The dive counter displayed in the
planning mode adds one to each new dive in the repetitive series.
The planning mode allows you to review the no-decompression
limits on the next dive in a series.
3.13 Dive planning mode
The dive planning mode PLAN NoDeco can be used to plan a dive
that does not require decompression. You enter the depth of your
upcoming dive, and Suunto Zoop Novo calculates the maximum
time you can stay at that depth without requiring decompression
stops.
38
The dive plan takes into account:
•
•
any calculated residual nitrogen
dive history from the past four days

3.15 Error state (algorithm lock)
Suunto Zoop 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 Zoop Novo enters an
error state and shows Er on the display. This indicates that the risk
of DCI has greatly increased.
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.
40
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 Zoop 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.
If you dive again in this error state, the algorithm lock time resets to
48 hours when you surface.
3.16 Personal and altitude adjustments
There are several factors that can affect your susceptibility to DCS.
Such factors vary between divers and from one day to another.
The personal factors which tend to increase the possibility of DCS
include:
•
•
•
•
•
•
•
•
exposure to cold water - less than 20°C (68 °F)
below average physical fitness level
fatigue
dehydration
stress
obesity
patent foramen ovale (PFO)
exercise before or after dive
41
The three-step personal setting can be used to adjust the algorithm
to fit your DCS susceptibility.

WARNING: Traveling to a higher altitude can temporarily cause
changes to the equilibrium of dissolved nitrogen in the body. It is
recommended that you acclimatize to the new altitude by waiting
at least three (3) hours before diving.
3.17 Power save mode
Suunto Zoop Novo display turns off after 30 minutes of inactivity to
save battery time. To turn the display back on, press any button.
3.18 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 Zoop Novo displays two different 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 Zoop Novo shows a STOP icon
and a three-minute countdown.
43
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 Zoop 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:
1. CEILING and STOP
2. Ceiling depth
3. Safety stop time
44
Wait at the ceiling until the mandatory safety stop warning
disappears.
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.
Deepstops activate when you dive deeper than 20 m (65.6 ft).
If the dive timer is on the screen when deepstop activates, the timer
is replaced with deepstop.
After deepstop is over, the user can change between deepstop and
the timer by long pressing the MODE button.
Deepstops are presented the same way as safety stops. Suunto Zoop
Novo notifies you that you are in the deepstop area by displaying:
•
•
•
•
CEILING in the top
DEEPSTOP in the center row

45
Deepstop is on by default in Air and Nitrox modes. To turn
deepstop off:
1. While in a dive mode, keep [DOWN] pressed.
2. Press [DOWN] to scroll to Deepstop and enter with [Select].
3. Press [UP] to toggle on/off.
4. Press [MODE] to exit.
3.19 Sample rate
The sample rate controls how often information from the dive is
saved to the active log. The default sample rate is 20 seconds in air
and nitrox modes, and 2 seconds in free dive mode.

Start and stop the stopwatch by pressing [SELECT].
NOTE: If a deepstop activates while you are using the
stopwatch, the timer field is not visible.
3.22 Surface and no-fly time
Once back at the surface, Suunto Zoop Novo continues to provide
post-dive safety information and alarms. If, after your dive, you
need to wait until flying, the no-fly symbol displays in all modes.
To access further information about your surface and no-fly times,
enter dive mode.
Suunto Zoop Novo shows the time since you surfaced in the Surf t.
field. The airplane symbol indicates that you should not fly. The
countdown until you will be safe to fly is shown in the No Fly field.
48
No-fly time is always at least 12 hours and equals desaturation time
when it is more than 12 hours. For desaturation times shorter than
70 minutes, the no-fly time is not displayed.
If decompression is omitted during a dive so that Suunto Zoop Novo
time is always 48 hours.
If a dive is done in Gauge mode (bottom timer), the no-fly time is 48
hours.
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 DCS. 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 sickness!
The Divers Alert Network (DAN) recommends the following on no-
fly times:
49
•
•
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
flying is recommended.
•
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.
3.23 Suunto RGBM
Suunto's decompression model development originates from the
1980s when Suunto implemented Bühlmann's model based on M-
50
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 significant as
they addressed a number of 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 a significant advancement on the classic
Haldane models, which do not predict free gas. The Suunto RGBM
provides additional safety through its ability to adapt to a variety of
situations and dive profiles.
3.23.1 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
51
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.
3.23.2 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.
52
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.
3.23.3 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 Zoop Novo does not display CNS% or OTU% but instead
displays the larger of the two in the OLF% field. OLF% value is the
Oxygen limit fraction or Oxygen Toxicity Exposure.
For example, it the diver’s maximum tolerated exposure for CNS% is
85% and the maximum tolerated exposure for OUT% is 80% the
OLF% displays the largest scaled value, here 85%.
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.
53
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.
3.24 Tones
Device tones can be turned on or off. When tones are off, there are
no audible alarms.

3. Press [DOWN] or [UP] to toggle on/off and confirm with
[SELECT].
4. Press [MODE] to exit.
3.25 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 Zoop Novo switches to dive state
when water is detected and the depth gauge senses water pressure
at 1.2 m (4 ft).
54
AC
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. See 4.1 Handling
NOTE: Moisture build-up around the water contact may cause
the dive mode to activate. This can happen, for example, when
washing your hands or sweating. To save battery power, deactivate
the water contact by cleaning it and/or drying it with a soft towel.
55
4 CARE AND SUPPORT
4.1 Handling guidelines
The Suunto Zoop Novo dive computer is a sophisticated precision
instrument. Although it is designed to withstand the rigors of
diving, you must treat it with the same proper care and caution as
any other precision instrument.
Handle the unit with care – do not knock or drop it.
Do not fasten the strap of your dive computer too tightly. You
should be able to insert your finger between the strap and your
wrist.
After use, rinse it with fresh water, mild soap, and carefully clean
the housing with a moist soft cloth or chamois.
Use only original Suunto accessories - damage caused by non-
original accessories is not covered by warranty.
Keep the water contact and depth sensors areas on the sides of the
watch clean using fresh water and a soft brush, such as a
toothbrush.
Never try to open the case of the dive computer. Have your Suunto
Zoop Novo serviced every two years or after 200 dives (whichever
comes first) by an authorized Suunto service center.
This service includes a general operational check, replacement of
the battery, and water resistance check. The service requires special
tools and training. Do not attempt to do any servicing yourself.
56
Should moisture appear inside the case or battery compartment,
immediately have the instrument checked by your Suunto service
center.
The optional scratch guard for Suunto Zoop Novo is designed to
help prevent the display from getting scratched. Scratch guards can
be purchased separately from your authorized Suunto dealer.
Should you detect scratches, cracks or other such flaws on the
display that may impair its durability, immediately contact your
authorized Suunto dealer.
Protect the unit from shock, extreme heat, direct sunlight, and
chemicals.
Store your dive computer in a dry place when you are not using it.
4.2 Battery replacement
Suunto Zoop Novo displays a battery symbol as a warning when the
power gets too low. When this happens, your Suunto Zoop Novo
should not be used for diving until the battery has been replaced.
Contact an authorized Suunto service center for battery
replacement. It is imperative that the change is made in a proper
manner to avoid any leakage of water into the battery
compartment or computer.
Defects caused by improper battery installation are not covered by
the warranty.
All history and logbook data, as well as the altitude, personal and
alarm settings, remain in the dive computer memory after the
battery change. Other settings revert back to default values.
57
4.3 Changing strap to bungee
Use the optional bungee adapter to change between wrist strap
and bungee cord as needed.
To install the bungee:
1. Turn the dive computer over.
2. Remove each strap by depressing one end of the spring bar with
a small flat-head screwdriver or spring bar removal tool.
3. Attach the bungee adapters to each side of the case with the
spring bars. Ensure the spring bars are firmly in position by
pushing down on each end of the bar.
4. Thread the bungee cord through the adapters and securely tie
the ends.
5. Pull hard on the bungee to ensure the adapters are in position
and the cord knot is tight.

of oxygen (O2) psi). The contingency partial pressure limit is 1.6
bar (23 psi). Dives beyond this limit risk
immediate oxygen toxicity.
