WARNING YOU ARE ADVISED TO AVOID FLYING ANY TIME THECOMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYSACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! Flying or traveling to a higheraltitude within the no-fly time can greatly increase the risk of DCI.Review the recommendations giv...

WARNING THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONALPERCENTAGE VALUES OF OXYGEN CONCENTRATION. DONOT ROUND UP FRACTIONAL PERCENTAGES! For example,31.8% oxygen should be entered as 31%. Rounding up will causenitrogen percentages to be understated and will affectdecompression calculations. If you want...

Locked bearings are stored in the memory for lateranalysis and are available the next time the compass is activated. TO LOCK A BEARING, PRESS SELECT. The Suu...

Explanation Symbol You are 120 (or 240) degrees from the locked bearing 4.4.3. Compass settings You can define the compass settings (declination and calibration) when in COMPASSmode: Declination You can compensate for the difference between true north and magnetic north byadjusting the compass decli...

ADJUST WITH UP AND DOWN. ACCEPT WITH SELECT. Calibration Because of changes in the surrounding magnetic field, the Suunto D6 electroniccompass occasionally needs to be re-calibrated. During the calibration process, thecompass adjusts itself to the surrounding magnetic field. As a basic rule, you sho...

5.7. Error conditions The dive computer has warning indicators that alert you to react to certain situationsthat would significantly increase the risk of DCI. If you do not respond to its warnings,the dive computer will enter an Error mode, indicating that the risk of DCI has greatlyincreased. If yo...

5.8. DIVE mode settings Suunto D6 has several user-definable functions, as well as depth and time-relatedalarms that you can set according to your personal preferences. The DIVE modesettings are dependent on the dive sub-mode chosen (AIR, EAN, GAUGE), so that,for example, nitrox settings are only av...

USE UP AND DOWN BUTTONS TO TOGGLE BETWEEN DIVE SETTINGS. NOTE The settings cannot be activated until 5 minutes has elapsed afterthe dive. 5.8.1. Setting the depth alarm You can set a depth alarm in the dive computer. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 41

In order to minimize the risk of error during a dive, it is highly recommended that themixes are set in the proper order. This means that as the mix number rises, so doesoxygen content, and this is the order they are usually used during the dive. Before adive, only set to “ON” the mixes you actually...

5.9.4. Diving at altitude The dive computer can be adjusted both for diving at altitude and also to increase theconservatism of the mathematical nitrogen model.When programming the instrument for the correct altitude, you need to select thecorrect Altitude Adjustment settings according to Table 5.5,...

5.9.5. Personal adjustments There are personal factors that can affect your susceptibility to DCI, which you canpredict in advance, and input into the decompression model. Such factors vary betweendivers and also for the same diver from one day to another. The three-step PersonalAdjustment setting i...

6. DIVING This section contains instructions on how to operate the dive computer and interpretits displays. You’ll find that this dive computer is easy to use and read. Each displayshows only the data relevant to that specific diving mode. 6.1. Diving in AIR mode (DIVEair) In this section, we look a...

• the time needed at the ceiling • the time needed at the Mandatory Safety Stop (if any) • the time needed to reach the surface after the ceiling and Safety Stops have beencompleted WARNING YOUR ACTUAL ASCENT TIME MAY BE LONGER THANDISPLAYED BY THE INSTRUMENT! The ascent time willincrease if you:• r...

WARNING NEVER ASCEND ABOVE THE CEILING! You must not ascendabove the ceiling during your decompression. In order to avoiddoing so by accident, you should stay somewhat below the ceiling. Display below the floor The blinking ASC TIME and an upward pointing arrow indicate that you are below thefloor. ...

UPWARD POINTING ARROW HAS DISAPPEARED AND ASC TIME LABEL HAS STOPPED BLINKING, MEANING YOU ARE IN THE DECOMPRESSION RANGE. Decompression will now begin, but is very slow. You should therefore continue yourascent. Display at the ceiling zone When you reach the ceiling zone, the display will show you ...

During the decompression stop, ASC TIME will count down towards zero. When theceiling moves upwards, you can ascend to the new ceiling. You may surface only afterthe ASC TIME and CEILING labels have disappeared, which means that thedecompression stop and any Mandatory Safety Stop have been completed...

6.2.1. Before diving in NITROX mode If set to the NITROX mode, the correct oxygen percentage of the gas in your cylindermust always be entered into the computer to ensure correct nitrogen and oxygencalculations. The dive computer adjusts its mathematical nitrogen and oxygencalculation models accordi...

NOTE If no button is pressed in 15 seconds, the dive computer will goback to the dive display without changing the gas mix. Uponascent, the computer prompts you to change gas when the PO 2 level you have set for the next mix allows a gas change.Theprompt is an audible 3 beeps and the current O 2 mix...

NOTE There is no ascent rate monitoring in the GAUGE mode. NOTE If you dive with the GAUGE mode, it is not possible to changebetween the modes before the no fly time has counted down. 72

7. AFTER DIVING 7.1. At the surface Once back at the surface, Suunto D6 continues to provide post-dive safety informationand alarms. Calculations to enable repetitive dive planning also help to maximize diversafety. 7.1.1. Surface interval An ascent to any depth shallower than 1.2 m/4 ft will cause ...

When entering the MEMplan mode, the display first briefly shows the remainingdesaturation time before going into plan mode.By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3m/10 ft increments ending at 45 m/150 ft. No-decompression limits longer than 99minare displayed ...

NOTE The Planning mode is disabled in GAUGE mode and in Errormode (see Section 5.7. Error conditions). The planning modecalculates no-decompression times for MIX1 only. If an additionalmix is enabled in the NITROX mode, it does not affect thecalculations in MEMplan mode. Higher Altitude and conserva...

NOTE Low temperature or an internal oxidation of the battery mayactivate the battery warning even though the battery has enoughcapacity. In this case, the warning usually disappears when theDIVE mode is activated again. 9.2. RGBM The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algorithm ...
