2. Keep DOWN pressed to enter General Settings.
3. Set time. See Time.
4. Set date. See Date.
5. Set units. See Units.
6. Press MODE to exit settings.

The default dive mode is Air. For more information on dive modes, see Dive modes.

Icons

Suunto Zoop Novo uses the following icons:

Activation and pre-checks

Unless the dive mode turned off, the dive mode activates automatically when you dive deeper than 1.2 m (4 ft). However, you should switch to dive mode before diving to check altitude and personal settings, battery condition and so on.

Each time your Suunto Zoop Novo enters dive mode, a series of automatic checks are performed. All graphical display elements are turned ON, and the backlight and the beep are activated. After this, your altitude and personal settings are displayed along with the maximum operating depth (MOD), gas content, and PO₂ values. Then the battery level is checked.

Between consecutive dives, the automatic checks also show current tissue saturation.

Before leaving on a dive trip, it is highly recommended that you switch to dive mode to make sure everything is functioning properly.

After the automatic checks, Suunto Zoop Novo enters surface mode. At this point, you should perform your manual checks before entering the water.

Ensure that:

1. Suunto Zoop Novo is in the correct mode and provides complete displays.
2. Altitude setting is correct.
3. Personal setting is correct.
4. Deepstops are set correctly.
5. Unit system is correct.
6. Correct temperature and depth are shown.
7. The alarm beeps.

Battery indicators

Temperature or internal oxidation can affect the battery voltage. If you store your Suunto Zoop Novo for a long period or use it in cold temperatures, the low battery warning may appear even though the battery has enough capacity.

In these cases, re-enter dive mode and check the battery power. If the battery is low, the Low Battery warning comes on.

If the low battery icon appears in surface mode, or if the display looks faded, the battery may be too low. Battery replacement is recommended.

Alarms, warnings and notifications

Suunto Zoop Novo has audible and visual alarms designed to let you know when important limits or presets are being reached.

The two audible alarm types indicating indicating high or low priority:

Alarm type	Sound pattern	Duration
High priority		2.4 s sound + 2.4 s break
Low priority		0.8 s sound + 3.2 s break

In addition, there are two audible guidance notifications:

Instructional beep	Sound pattern	Interpretation
Ascending		Start ascending
Descending		Start descending

Suunto Zoop Novo displays information during the alarm breaks in order to save battery life.

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.

2. Keep DOWN pressed to enter apnea timer settings.
3. Adjust the ventilation time with UP or DOWN and confirm with SELECT.
4. Adjust the increment time with UP or DOWN and confirm with SELECT.
5. Adjust the number of intervals with UP or DOWN and confirm with SELECT.

To use the apnea timer:

1. Press SELECT to start the first interval. The timer counts down the ventilation time. The countdown continues up to -0:30 seconds beyond the defined ventilation time.
2. Press SELECT to start the apnea cycle. You can start this at any time during the ventilation countdown. The apnea time is not defined in the watch. It is as long or short as you choose.
3. Press SELECT again to start the next ventilation cycle.
4. Repeat until the end of the defined number of intervals.
5. Press MODE to exit the apnea timer.

You can reset the apnea timer by keeping SELECT pressed.

The apnea timer supports up to 20 intervals, but this is dependent on the ventilation and increment times. The last ventilation cycle cannot be shorter than 0:05 seconds or longer than 20:00 minutes.

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 ASC TIME, and a CEILING indicator appears. An upward pointing arrow also prompts you to start your ascent.

Suunto Zoop 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 defined gases

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.

In other words, rather than requiring you to make stops at fixed depths, the dive computer lets you decompress within a range of depths. This is known as continuous decompression.

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 floor is the deepest depth at which the decompression stop time does not increase. Decompression starts when you pass this depth during your ascent.
• The decompression range is the depth range between the ceiling and floor. Within this range, decompression takes place. However, it is important to remember that the decompression slower at or close to the floor compared to the ceiling zone.

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.

When conditions are rough, it may be difficult to maintain a constant depth near the surface. 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.

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
• Time needed for decompression
• Time needed for extra safety stops if ascending too fast during the dive

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 Zoop Novo penalizes such actions with additional stops or other measures, either during the dive or on following dives. For more information, see Safety stops and deepstops.

Suunto Zoop 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.

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 field, and the minimum total ascent time on the right side.

Below is an example of a decompression dive with a ceiling of 3 m and total ascent time of 9 minutes.

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.

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 (Error state (algorithm lock)).

Depth alarm

By default the depth alarm sounds at 30 m (100 ft). You can adjust the depth according to your personal preference or switch it off.

To adjust the depth alarm:

1. While in a dive mode, keep DOWN pressed to enter settings.
2. Press UP to scroll to Depth Alarm and press SELECT.
3. Press UP to toggle the alarm on/off and confirm with SELECT.
4. Adjust depth with DOWN or UP and accept with SELECT.
5. Press MODE to exit.

When the depth alarm activates, the backlight blinks and the low priority audible alarm pattern sounds. Acknowledge the alarm by pressing any button.

Display contrast

You can adjust the contrast of the display according to your preference or, for example, to suite changing dive conditions.

1. While in time mode, keep DOWN pressed.
2. Press UP to scroll to Contrast and press Select.
3. Use DOWN or UP to change the contrast from 0 (lowest) to 10 (highest).
4. Press MODE to exit.

Dive history

Suunto Zoop Novo has a detailed logbook and dive history available in memory mode.

The logbook contains a sophisticated dive profile for each recorded dive. The time between each data point saved in the log is based on the configurable sample rate (see Sample rate).

The dive history is a summary of all recorded dives.

To access dive history:

1. Press MODE until you see MEM.
2. Switch between History and Logbookwith DOWN or UP.
3. When you are viewing the history or logbook, you can press MODE to go back and select the other one. Press MODE a second time to exit.

History

When you have entered the dive history view, you can switch between Scuba History and Free Dive History with DOWN and UP.

Scuba dive history shows you a summary of the following:

• Dive hours
• Total number of dives
• Maximum depth

The scuba dive history records a maximum of 999 dives and 999 diving hours. When these limits are reached, the counters reset to zero.

Free dive history shows the following:

• the deepest and the longest dives of all free dives
• the cumulative dive time in hours and minutes
• the total number of dives

The free dive history records a maximum of 999 dives and 99:59 diving hours. When these limits are reached, the counters are reset to zero.

Logbook

Each log has three pages:

1. Main page

• maximum depth
• date of dive
• type of dive (indicated by first letter of dive mode, e.g. A for Air mode)
• dive start time
• dive number – from oldest to newest
• gas percentage(s) of the first used gas mix
• total dive time (in minutes in all modes)
• Surface time and warnings page

• maximum depth
• surface time after previous dive
• average depth
• warnings
• OLF% (if applicable)
• Dive profile graph

• water temperature
• depth/time profile of the dive

Press UP to scroll through the dive profile graph or keep UP pressed to auto-scroll.

The dive profile graph shows point by point dive information such as depth, compass heading, decompression info, ceiling and ascent time.

The End of Logs text is displayed between the oldest and most recent dive.

The logbook capacity depends on the sample rate.

If the memory is full, when new dives are added, the oldest dives are deleted.

The contents of the memory remain when the battery is changed (providing that the battery has been replaced according to the instructions).

Dive modes

Suunto Zoop Novo has the following dive modes:

• Air: for diving with regular air
• Nitrox: for diving using oxygen-enriched gas mixtures
• Gauge: for using the dive computer as a bottom timer
• Free: for freediving
• Off: turns dive mode off completely; the dive computer does not automatically switch the dive mode when submerged and dive planning mode is hidden

By default, Air mode is activated when you enter dive mode. You can change which mode is activated or turn dive mode off under the general settings.

To change dive modes:

1. While in time mode, keep DOWN pressed.
2. Press SELECT to enter Dive Mode.
3. Change to the desired mode with UP or DOWN and confirm with SELECT.
4. Press MODE to exit.

Each dive mode has its own settings which you need to adjust while in the given mode.

To modify dive mode settings:

1. While in a given dive mode, keep DOWN pressed.
2. Press DOWN or UP to scroll through the settings.
3. Press SELECT to enter a setting.
4. Adjust the setting with DOWN or Up and confirm with SELECT.

Air mode

Air mode is for diving with regular air and has the following settings:

• Personal/altitude adjustment (see Personal and altitude adjustments)
• Depth alarm (see Depth alarm)
• Dive time alarm (see Dive time alarm)
• Sample rate (see Sample rate)
• Deepstop (see Safety stops and deepstops)

Nitrox mode

Nitrox mode is for diving with oxygen-enriched gas mixtures.

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 Personal and altitude adjustments)
• Depth alarm (see Depth alarm)
• Dive time alarm (see Dive time alarm)
• Sample rate (see Sample rate)
• Deepstop (see Safety stops and deepstops)

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 (O₂%) setting is 21% (air) and oxygen partial pressure (PO₂) setting is 1.4 bar (20 psi).

To modify gas mix settings:

1. While in Nitrox mode, keep DOWN pressed.
2. Press SELECT to enter the Nitrox setting.
3. Adjust the O₂ value with DOWN or UP to match the oxygen percentage of your tank and confirm with SELECT.

4. Adjust the PO₂ (oxygen partial pressure) value with DOWN or UP and accept with SELECT.
5. Adjust other settings as needed.
6. Press MODE to exit.

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.

Gauge mode has the following settings

• Depth alarm (see Depth alarm)
• Dive time alarm (see Dive time alarm)
• Sample rate (see Sample rate)

Gauge mode is a bottom timer only and thus includes no decompression information or calculations.

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 Depth notifications)
• Depth alarm (see Depth alarm)
• Dive time alarm (see Dive time alarm)
• Surface timer (see Surface and no-fly time )
• Sample rate (see Sample rate)

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.

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.
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.

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.

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.

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.

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.

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.

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.

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.

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

The three-step personal setting can be used to adjust the algorithm to fit your DCS susceptibility.

In addition to the personal setting, Suunto Zoop Novo can be adjusted for diving at different altitudes. This adjusts the decompression calculation according to the selected altitude adjustment.

To change the personal and altitude adjustment settings:

1. While in a dive mode, keep DOWN pressed.
2. Press SELECT to enter Personal Altitude settings.
3. Press UP to change the Personal adjustment and confirm with SELECT.
4. Press UP to change the Altitude adjustment and confirm with SELECT.
5. Press MODE to exit.

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.

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.

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

Wait at the ceiling until the mandatory safety stop warning disappears.

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

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.

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.

The sample rate options in air and nitrox modes are: 10, 20, 30 and 60 seconds.

The sample rate options in free dive mode are: 1, 2 and 5 seconds.

Software version

You can check the software version and battery status of Suunto Zoop Novo under the general settings.

1. While in time mode, keep DOWN pressed.
2. Press UP to scroll to Version and press SELECT.
3. The software version is displayed along with the battery voltage.

Stopwatch

The stopwatch can be used to measure elapsed and split times.

To activate the stopwatch:

1. While in time mode, scroll through the bottom row view by pressing UP or DOWN until the stopwatch is displayed.

2. Press SELECT to start/stop the stopwatch.
3. Press DOWN to take split times.
4. Keep SELECT pressed to reset the stopwatch.

After stopping the stopwatch, you can scroll through the split times with DOWN.

You can also use the stopwatch while diving for various timing purposes. To activate the stopwatch in dive mode, keep MODE pressed.

Start and stop the stopwatch by pressing SELECT.

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.

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 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.

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 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.

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 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.

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.

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.

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, if the diver’s maximum tolerated exposure for CNS% is 85% and the maximum tolerated exposure for OTU% 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.

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.

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).

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.

Handling guidelines

Handle Suunto Zoop Novo with care. The sensitive internal electronic components may be damaged if the device is dropped or otherwise mishandled.

When travelling with this dive computer, ensure that it is packed securely in check-in or carry-on luggage. It should be placed in a bag or other container where it cannot move around bumped or easily hit.

Do not try to open or repair Suunto Zoop Novo by yourself. If you are experiencing problems with the device, please contact your nearest authorized Suunto Service Center.

Wash and dry the dive computer after use. Rinse very carefully after any salt-water dive.

Pay special attention to the pressure sensor area, water contacts, pushers, and USB cable port. If you use the USB cable before washing the dive computer, the cable (device end) should be rinsed as well.

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.

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.

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.
