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.

3.3 Apnea timer  
You can use the apnea timer for interval training when freediving.  
You can adjust the following settings:  
Vent.: ventilation time; this is the starting duration of the time  
your breathing time. The time is increased by the increment time  
for each interval.  
Incr: increment time; this is added to the ventilation time for  
each interval. For example, if your ventilation time is 1:00  
minute and your increment time is 0:30 seconds, the first interval  
ventilation is 1:00, the second is 1:30, the third is 2:00, and so on.  
Repeats: number of intervals  
To adjust apnea timer settings:  
1. While in time mode, keep [UP] pressed to enter the apnea timer  
view.  
2s  
2. Keep [DOWN] pressed to enter apnea timer settings.

Personal/altitude adjustment (see 3.16 Personal and altitude  
Depth alarm (see 3.8 Depth alarm)  
Dive time alarm (see 3.14 Dive time alarm)  
Sample rate (see 3.19 Sample rate)  
3.11.2 Nitrox mode  
Nitrox mode is for diving with oxygen-enriched gas mixtures.  
33  
 
   
Diving with nitrox allows you to increase bottom times or reduce  
the risk of decompression illness. However, when the gas mix is  
altered or depth increased, the oxygen partial pressure is generally  
increased. Suunto Zoop Novo provides you with information to  
adjust your dive and stay within safe limits.  
NITROX mode has the following settings  
Nitrox (gas mixture)  
Personal/altitude adjustment (see 3.16 Personal and altitude  
Depth alarm (see 3.8 Depth alarm)  
Dive time alarm (see 3.14 Dive time alarm)  
Sample rate (see 3.19 Sample rate)  
In NITROX mode, both the percentage of oxygen in your tank and  
the oxygen partial pressure limit must be entered into Suunto Zoop  
Novo.  
This ensures correct nitrogen and oxygen calculations and the  
correct maximum operating depth (MOD), which is based on your  
entered values.  
The default oxygen percentage (O %) setting is 21% (air) and  
2
oxygen partial pressure (PO ) setting is 1.4 bar (20 psi).

2
[UP] and accept with [SELECT].  
5. Adjust other settings as needed.  
6. Press [MODE] to exit.  
NOTE: If the oxygen content of a mix is set to 22% or above,  
the setting value remains until changed. It does not automatically  
revert back to 21%.  
3.11.3 Gauge mode  
With Gauge mode, you can use Suunto Zoop Novo as a bottom  
timer.  
The timer in the center of the display shows dive time in minutes  
and seconds and activates at the start of the dive. The total running  
dive time, in minutes, is in the lower right corner.  
The timer in the center of the display can be used as a stopwatch by  
pressing [SELECT] during the dive.  
Pressing [SELECT] resets the main timer and adds a bookmark to the  
dive log. The previously-timed interval is displayed below the main  
timer.  
35  
 
 
Gauge mode has the following settings  
Depth alarm (see 3.8 Depth alarm)  
Dive time alarm (see 3.14 Dive time alarm)  
Sample rate (see 3.19 Sample rate)  
Gauge mode is a bottom timer only and thus includes no  
decompression information or calculations.  
3.11.4 Free mode  
With Free mode, Suunto Zoop Novo can be used as a freediving  
instrument. The dive time is indicated in minutes and seconds in the  
center of the display.  
The free dive starts at 1.2 m (4 ft) and ends when your depth is less  
than 0.9 m (3 ft).  
Free mode has the following settings:  
Depth notifications (see 11.4.1 Depth notifications)  
Depth alarm (see 3.8 Depth alarm)

3.11.4.1 Depth notifications  
You can define up to five independent depth notifications for  
freediving, for example, to alert you to start free falling or mouth  
filling. Each notification has a defined depth and can be turned on  
or off.  
When you reach the notification depth, the backlight blinks and the  
low priority audible alarm sounds.  
To define depth notifications:  
1. While in Free mode, keep [DOWN] pressed.  
2. Press [SELECT] to enter the Depth Notify settings.  
3. Scroll through the notifications with [DOWN] or [UP] and enter a  
notification with [SELECT].  
4. Press [DOWN] or [UP] to toggle the notification On/Off and  
confirm with [SELECT].  
5. Adjust the depth with [DOWN] or [UP] and confirm with  
[SELECT].  
6. Scroll to the next notification to modify or press [MODE] to exit.  
3.11.4.2 Surface countdown timer  
While freediving, you can use the surface countdown timer to help  
you prepare yourself for you next dive. Suunto Zoop Novo starts the  
countdown as soon as you reach 1.2 m (4 ft).  
To set the surface countdown timer:  
1. While in Free mode, keep [DOWN] pressed.  
2. Press [UP] to scroll to Surf. Time Notify.  
37  
 
 
3. Press [DOWN] or [UP] to toggle the timer on and confirm with  
[SELECT].  
4. Adjust the countdown duration with [DOWN] or [UP] and  
conform with [SELECT].  
5. Press [MODE] to exit.  
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  
To plan dives:  
1. Press [MODE] until you see PLAN NODEC.  
2. The display briefly shows your remaining desaturation time  
before continuing to the planning display.  
3. Press [DOWN] or [UP] to scroll your upcoming dive depths. The  
depth moves in 3 m (10 ft) increments from 9 m – 45 m (30 ft –  
150 ft). The no-decompression time limit for the selected depth  
is shown in the center of the display.  
If you have dived at least once with Suunto Zoop Novo, the  
SURFTIME + field appears. You can adjust the surface time with  
[UP].  
4. Between consecutive dives, you can press [SELECT] to adjust  
surface time.  
5. Press [MODE] to exit.  
NOTE: The dive planning mode is disabled if the dive computer  
dive mode is off or in Gauge mode.  
3.14 Dive time alarm  
The dive time alarm can be activated and used for several purposes  
to add to your diving safety. It is simply a countdown timer in  
minutes.  
39  
 
 
To set the dive time alarm:  
1. While in a relevant dive mode, keep [DOWN] pressed.  
2. Press [DOWN] or [UP] to scroll to ALARM TIME.  
3. Press [UP] to toggle the alarm on and press [SELECT] to confirm.  
4. Adjust the duration with [UP] or [DOWN] and accept with  
[SELECT].  
5. Press [MODE] to exit.  
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.

5. Press [MODE] to exit.  
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  
Stop depth  
Countdown timer  
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.  
To change the sample rate:  
1. While in a dive mode, keep [DOWN] pressed.  
2. Press [UP] to scroll to Sample Rate and press [SELECT].  
3. Press [DOWN] or [UP] to change the rate and confirm with  
[SELECT].  
4. Press MODE to exit.

purposes. To activate the stopwatch in dive mode, keep [MODE]  
pressed.  
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  
enters error state (see 3.15 Error state (algorithm lock)), the no-fly  
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.  
To set tones:  
1. While in time mode, keep [DOWN] pressed.  
2. Press [DOWN] or [UP] to scroll to Tones and press [SELECT].  
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.

5.7 Terms  
Term  
What it means  
A dive made at an elevation greater than 300 m  
(1000 ft) above sea level.  
Altitude dive  
The speed at which the diver ascends toward the  
surface.  
Ascent rate  
Ascent time  
The minimum amount of time needed to reach  
the surface on a decompression stop dive.  
On a decompression stop dive, the shallowest  
depth to which a diver may ascend based on  
computed inert gas load.  
Ceiling  
CNS  
Central nervous system toxicity. Toxicity is caused  
by oxygen. Can cause a variety of neurological  
symptoms. The most important of which is an  
epileptic-like convulsion which can cause a diver  
to drown.  
66  
 
 
Term  
What it means  
CNS%  
Central nervous system toxicity limit fraction.  
Compartment See "Tissue group".  
Suunto DM5 with Movescount, a software for  
DM5  
managing your dives.  
Time spent at a decompression stop, or range,  
Decompression before surfacing, to allow absorbed nitrogen to  
escape naturally from tissues.  
On a decompression stop dive, the depth range  
Decompression  
between the floor and the ceiling within which a  
range  
diver must stop for some time during ascent.  
Decompression sickness/illness. Any of a variety  
of maladies resulting either directly or indirectly  
DCS  
from the formation of nitrogen bubbles in tissues  
or body fluids, as a result of inadequately  
controlled decompression.  
A group of repetitive dives between which the  
dive computer indicates some nitrogen loading is  
present. When nitrogen loading reaches zero the  
dive computer deactivates.  
Dive series  
Dive time  
Elapsed time between leaving the surface to  
descend, and returning to the surface at the end  
of a dive.  
67  
 
Term  
What it means  
The deepest depth during a decompression stop  
dive at which decompression takes place.  
Floor  
Helium percentage or helium fraction in the  
breathing gas.  
He%  
MOD  
Maximum operating depth of a breathing gas is  
the depth at which the partial pressure of  
oxygen (PO ) of the gas mix exceeds a safe limit.  
2
A single or repetitive dive that includes time  
spent at various depths and whose no  
Multi level dive decompression limits are therefore not  
determined solely by the maximum depth  
attained.  
In sports diving, refers to any mix with a higher  
Nitrox (Nx)  
fraction of oxygen than standard air.  
No deco (No  
Any dive which permits a direct, uninterrupted  
decompression  
ascent to the surface at any time.  
stop time)  
No dec time  
OC  
Abbreviation for no decompression time limit.  
Open-circuit. Scuba that exhausts all exhaled gas.  
Oxygen limit fraction. The diver’s current oxygen  
toxicity exposure.  
OLF%  
68  
 
Term  
O %  
What it means  
Oxygen percentage or oxygen fraction in the  
breathing gas. Standard air has 21% oxygen.  
2
Limits the maximum depth to which the nitrox  
mixture can be safely used. The maximum partial  
Partial pressure pressure limit for enriched air diving is 1.4 bar (20  
of oxygen (O2) psi). The contingency partial pressure limit is 1.6  
bar (23 psi). Dives beyond this limit risk  
immediate oxygen toxicity.

Modern algorithm for tracking both dissolved  
bubble model and free gas in divers.  
(RGBM)  
Any dive whose decompression time limits are  
Repetitive dive affected by residual nitrogen absorbed during  
previous dives.  
Residual  
nitrogen  
The amount of excess nitrogen remaining in a  
diver after one or more dives.  
Scuba  
Self-contained underwater breathing apparatus.  
Elapsed time between surfacing from a dive and  
beginning a descent for the subsequent dive.  
Surface time  
Theoretical concept used to model bodily tissues  
for the construction of decompression tables or  
calculations.
