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 D6i 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 D6i enters surface mode. At this point, you should perform your manual checks before entering the water.

Ensure that:

1. Suunto D6i 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.

Wireless Transmitter pre-check

If the optional wireless tank pressure transmitter is used, check that:

1. Tank gas and O₂ settings are correct.
2. The transmitter is properly installed and the tank valve is open.
3. The transmitter and Suunto D6i are paired.
4. The transmitter is sending data (wireless transmission icon blinks, tank pressure is displayed).
5. There is no transmitter low battery warning.
6. There is enough gas for your planned dive. Check the pressure reading against your back-up pressure gauge.

Battery indicators

Temperature or internal oxidation can affect the battery voltage. If you store your Suunto D6i 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.

1. While in the compass display, keep DOWN pressed.
2. Press DOWN to scroll to Timeout and press SELECT.
3. Adjust the timeout time with DOWN or UP.
4. Press MODE to exit.

Setting bearing lock

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:

1. With the compass active, hold the watch in front of you and turn yourself towards your target.
2. Press SELECT to lock the current degree displayed on the watch as your bearing.
3. Press SELECT to clear the lock.

If, at any point, your bearing moves outside the compass display, right or left arrows appear to show turn direction.

Suunto D6i provides help for navigating square and triangular patterns, as well as navigating a return heading with the following symbols.

Symbol	Explanation
	You are traveling towards the locked bearing.
	You are 90 (or 270) degrees from the locked bearing.
	You are 180 degrees from the locked bearing.
	You are 120 (or 240) degrees from the locked bearing.

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 D6i 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 D6i 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 D6i 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)).

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.

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.

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 D6i provides you with information to adjust your dive and stay within safe limits.

Nitrox mode has the following settings

• Nitrox (gas mixture): define up to three mixes
• 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)
• Air time (see Air time)

In Nitrox mode, both the percentage of oxygen in your tank and the oxygen partial pressure limit must be entered into Suunto D6i.

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).

The gas mixes may be tagged as Primary, Secondary or Off. One of the gases is always set as Primary and the other gases may have any status. The decompression calculation is based on mixes that are defines as Primary gases.

Error state (algorithm lock)

Suunto D6i 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 D6i 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 D6i 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 D6i 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.

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 D6i 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 D6i 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 D6i 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 D6i 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 D6i 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 D6i 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 D6i 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 D6i 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.

Dive numbering

If the Suunto D6i 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 D6i 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.

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 D6i 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.

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.

The remaining air time is not displayed when either deepstops or the decompression ceiling has been activated. You can check remaining air time by keeping DOWN pressed.

Temperature changes affect the tank pressure and consequently the air time calculation.

Low air pressure warnings

The dive computer warns you with two (2) audible double beeps and a blinking pressure display when the tank pressure reaches 50 bar (700 psi).

Two (2) double beeps sound when the tank pressure reaches the defined alarm pressure and when the remaining time reaches zero.

Wireless transmission

To enable wireless transmission of tank pressure data to Suunto D6i requires:

1. Installation of Suunto Wireless Transmitter onto your regulator.
2. Pairing the transmitter to your Suunto D6i.
3. Enabling the wireless integration in your Suunto D6i settings.

The transmitter enters power saving mode with slower data transmission rate if the tank pressure remains unchanged for more than five (5) minutes.

The optional transmitter sends out a low battery (batt) warning when its battery voltage is getting low. This is shown intermittently instead of the pressure reading. When you get this warning, the tank pressure transmitter's battery needs to be replaced.

Installing and pairing transmitter

When purchasing the Suunto Wireless Transmitter, we strongly recommend that you have your Suunto representative attach the transmitter to the first stage of your regulator.

The unit needs to be undergo a pressure test after installation and typically this requires a trained technician.

In order to receive wireless data, the transmitter and the Suunto D6i 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 D6i is within 0.3 m (1 ft) of the transmitter, it receives and stores that code. The transmitter and Suunto D6i are now paired. Suunto D6i 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.

To assign a new transmitter code:

1. Slowly open the tank valve fully to pressurize the system.
2. Immediately close the tank valve.
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 D6i:

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 D6i 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.

Transmitted data

After pairing, your Suunto D6i receives tank pressure data from the transmitter.

Any time the Suunto D6i receives a signal, one of the following symbols is shown in the lower left corner of the display.

Tank pressure alarm

There are two tank pressure alarms. The first is fixed at 50 bar (700 psi) and cannot be changed.

The second is user configurable. It can be turned on or off and can be used for a pressure range of 10–200 bar (200-3000 psi).

To set the tank pressure alarm value:

1. While in a dive mode, keep DOWN pressed to enter settings.
2. Press DOWN to scroll to Tank Press Alarm and press SELECT.
3. Press UP to turn the alarm on and confirm with SELECT.
4. Adjust the pressure level with UP or DOWN and confirm with SELECT.
5. Press MODE to exit.

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 D6i 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

The Suunto D6i 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 D6i 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.

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 D6i 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.

Water resistance

Suunto D6i is water resistant to 150 meters (492 ft) in compliance with the dive watch standard ISO 6425.

To maintain water resistance, it is recommended to:

• never use the device for other than intended use.
• contact an authorized Suunto service center, distributor or retailer for any repairs.
• keep the device clean from dirt and sand.
• never attempt to open the case yourself.
• avoid subjecting the device to rapid air and water temperature changes.
• always clean your device with fresh water if subjected to salt water.
• never knock or drop the device.

Battery replacement

Suunto D6i displays a battery symbol as a warning when the power gets too low. When this happens, your Suunto D6i 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.
