YOU ARE ADVISED TO AVOID FLYING ANY TIME THE WARNING 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 DCI.
Page 13
THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL WARNING PERCENTAGE VALUES OF OXYGEN CONCENTRATION. DO NOT ROUND UP FRACTIONAL PERCENTAGES! For example, 31.8% oxygen should be entered as 31%. Rounding up will cause nitrogen percentages to be understated and will affect decompression calculations. If there is a desire to adjust the computer to provide more conservative calculations, use the personal adjustment feature to affect decompression cal- culations or reduce the PO...

Page 16
Failure to take action to reduce oxygen exposure after the warning is given can rapidly increase the risk of oxygen tox- icity, injury, or death Suunto recommends that you receive training in Free diving WARNING techniques and physiology before conducting breath hold dives.
Page 17
Using the Suunto Dive Planner software is not a substitute WARNING 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 special- ized training for the type of diving they are doing.
Page 18
It is not possible to change to AIR mode after a dive in NI- NOTE TROX mode, before the No-fly time has elapsed. When planning both air and nitrox dives during the same dive series, you should set the instrument in NITROX mode and modify the gas mix accordingly.

BEFORE getting into the water. 4.1. TIME mode settings The first thing to do with your Suunto D6i is to set the TIME mode shortcuts: the time, alarm, dual time, date, units, backlight, contrast, and tones.
Page 25
The seconds display reverts to date display after 5 minutes NOTE in order to save battery power. The display is illuminated by holding down the MODE button NOTE for more than 2 seconds. Now that after you know how to toggle between the shortcuts, you can start to set them.
4.1.1. Setting the alarm The dive computer has a daily alarm function. The alarm can be set to be activated only once, on weekdays or every day. When the daily alarm activates, the screen blinks and the alarm sounds for 60 seconds. Press any button to stop the alarm. ADJUST WITH UP AND DOWN BUTTONS.
4.1.3. Setting the dual time In the Dual Time setting mode, you are able to select the hour and minute of a dual time, which is useful when traveling to a different time zone. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.6. Setting the backlight In the Backlight setting mode, you are able to turn the backlight ON or OFF and to define how long it stays on for (5, 10, 20, 30, or 60 seconds). When the backlight is turned OFF, it does not illuminate when NOTE an alarm sounds.
When the tones are off, there are no audible alarms. NOTE 4.2. Stopwatch The Stopwatch function in Suunto D6i measures elapsed and split times. A separate stopwatch (dive timer) can also be used in the DIVE mode. For more in- formation, refer to Section 6.1.6. Stopwatch (Timer).
USE DOWN BUTTON TO START STOPWATCH AND TAKE A SPLIT TIME. THE UP BUTTON STOPS THE STOPWATCH. IF YOU HAVE TAKEN SPLIT TIMES, YOU CAN SCROLL THEM BY SHORT PRESSING THE UP BUTTON. LONG PRESSING UP RESETS THE STOPWATCH. 4.3. AC water contacts The water and data transfer contact is located on the side of the case.
4.4. Learning how to use your compass Suunto D6i integrates a digital compass, which can be used both while diving and on dry land, and can be accessed from either the DIVE mode or TIME mode.
UP/DOWN buttons. 4.4.1. Compass display The Suunto D6i displays the compass as a graphical representation of a compass rose. The rose displays the cardinal and half cardinal points, in addition to which, the current bearing is also displayed numerically.
TO LOCK A BEARING, PRESS SELECT. The Suunto D6i also provides help for navigating square and triangular patterns, as well as navigating a return heading. This is made possible by following graphical symbols in the center of the compass display: Table 4.1.
COMPASS mode: Calibration Because of changes in the surrounding magnetic field, the Suunto D6i electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field . As a basic rule, you should calibrate the compass whenever it does not seem to operate properly, or after replacing the dive computer's battery.
Page 35
Strong electromagnetic fields, such as power lines, stereo speakers, and magnets can affect the compass calibration. Therefore, it is advisable to calibrate the compass if your Suunto D6i has been exposed to these fields. When traveling overseas, it is recommended that you recalib- NOTE rate the compass at the new location before using it.
Page 36
Move to another location and try to calibrate the compass again. If the calibration continues to fail, contact an authorized Suunto service center. Declination You can compensate for the difference between true north and magnetic north by adjusting the compass declination.
ADJUST WITH UP AND DOWN. ACCEPT WITH SELECT. Time-out You can set the compass time-out from 1 to 20 minutes. After the set time has passed from the latest button press, the dive computer returns to the TIME or DIVE mode from the COMPASS mode.
Page 38
In the Apnea Timer, long press DOWN to enter settings in which you can define the duration of the ventilation period and the incremental increase/decrease in time for each cycle (repetition). You can adjust values with the UP and DOWN buttons.
It is a significant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto Technical RGBM is additional safety through its ability to adapt to a variety of situations...
Mandatory Safety Stop, has been introduced. The combination of stop types depends on the user settings and the specific dive situation. To get the most from the Suunto Technical RGBM safety benefits, refer to Sec- tion 5.8.10. Setting the deep stops and Section 5.11. Deep stops.
In the event that a required gas is not available at all, decompress for as long as you can by using the next most suitable gas that has the highest oxygen content. Notice that the oxygen content should be low enough to not violate the maximum partial pressure of oxygen (PO 5.3.
Suunto recommends that you receive training in freediving WARNING techniques and physiology before conducting breath hold dives. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause a diver to commit errors that may lead to serious injury or death.

5.8. DIVE mode settings Suunto D6i has several user-definable functions, as well as depth and time-related alarms that you can set according to your personal preferences. The DIVE mode settings are dependent on the dive submode chosen (AIR, NITROX, GAUGE, FREE), so that, for example, nitrox settings are only available in the NITROX submode.
Page 56
Setting AIR mode NITROX mode GAUGE mode FREE mode Surf time notify alarm Sample rate Deep stop Air time Units The figure below shows how to enter the DIVE mode settings menu. USE UP AND DOWN BUTTONS TO TOGGLE BETWEEN DIVE SETTINGS.
5.8.1. Setting the nitrox values If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder (and additional gases) must always be entered into the computer to ensure correct nitrogen and oxygen calculations. In the NITROX setting mode, the equivalent maximum operating depth (MOD), based on the chosen setting, is displayed.
Page 58
To view the most pessimistic ascent schedule, that is, a schedule for the situation in which the gases are not changed at all, you can set the mix gas(es) as Secondary gas, and the time it takes to finish the decompression using the current breathing gas is shown as the ASC time.
5.8.2. Setting the personal/altitude adjustments The current Altitude and Personal Adjustment settings are displayed in the startup screen when entering the DIVE mode. If the mode does not match the altitude or personal conditions (refer to Section 5.9.4. Diving at altitude and Section 5.9.5. Per- sonal adjustments), it is imperative that you enter the correct selection before diving.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.4. Setting the tank pressure alarm The tank pressure alarm can be set "ON" or "OFF" and in the range of 10–200 bar. The alarm is the secondary cylinder pressure alarm point. The alarm is activated when the tank pressure drops below the set limit.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.8.6. Setting the depth notify alarm (FREE mode) You can set five independent Depth Notify Alarms to indicate a certain depth, for ex- ample, start of free falling or mouth filling in freediving. ADJUST WITH UP AND DOWN BUTTONS.
5.8.8. Setting the surface time notify alarm (FREE mode) You can set the Surface Time Notify Alarm to indicate the length of the surface time before a new dive. Suunto D6i starts counting the time automatically when you surface (at 0.5 m/1.6 ft).
The factory default setting is 20 seconds. You can set the dive profile sample rate in free dive to 1, 2, or 5 seconds. The sample rate for gauge, nitrox and air dives is 10, 20, 30, or 60 seconds. ADJUST WITH UP AND DOWN BUTTONS.
5.8.11. Setting the air time In the Air Time setting mode, the remaining air time display can be set "ON" or "OFF" depending on whether estimated remaining air time display is used or not. Air Time can only be displayed when the wireless tank pressure transmitter is in use. 5.8.12.
5.9.1. Accessing DIVE mode The Suunto D6i has four diving modes: AIR mode for diving with standard air only, NITROX mode for diving with oxygen enriched mixtures, GAUGE mode for use as a bottom timer and FREE mode for freediving.
Page 66
(between two consecutive dives) the dive computer also displayes the current tissue saturation graph. A few seconds later the battery power indicator is shown. SUUNTO STRONGLY RECOMMENDS THAT SPORT WARNING DIVERS LIMIT THEIR MAXIMUM DEPTH TO 40 M /130 FT...

A TISSUE SATURATION GRAPH IS DISPLAYED BETWEEN DIVES WHEN DIVE MODE IS ACTIVATED. ON X-AXIS THE FAST TISSUES ARE ON LEFT AND SLOW TISSUES ON RIGHT. ON Y-AXIS, CALCULATED PERCENTUAL TISSUE SATURATION VALUES BASED ON RGBM ARE SHOWN. Y-AXIS RANGES FROM 0% TO 100%.
the oxygen partial pressure limits are set correctly • For more information on the NITROX mode, please refer to Section 6.2. Diving in NI- TROX mode (DIVE Nitrox). The dive computer is now ready for diving. 5.9.3. Battery power indication Temperature or internal oxidation of the battery affect the battery voltage.
The optional wireless pressure 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.
Traveling to a higher elevation can temporarily cause a change WARNING in the equilibrium of dissolved nitrogen in the body. It is recom- mended that you acclimatize to the new altitude by waiting at least three (3) hours before diving. 5.9.5.
Page 71
This feature is used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment setting with the help of Table 5.7, Personal Adjustment settings. In ideal conditions, retain the default setting, P0. If conditions are more difficult, or any of the factors which tend to increase the possibility of DCI exist, select P1, or even the most conservative P2.
The reasons for performing a Safety Stop in- clude: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D6i displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.10.1. Recommended Safety Stops With every dive over 10 meters, there is a three-minute countdown for the Recommen- ded Safety Stop, to be taken in the 3–6 m/10–20 ft range.
(5) seconds, the microbubble build-up is predicted to be more than is allowed for in the decompression model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.
Deep stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation. The Suunto RGBM model calculates deep stops iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth. After the first Deep stop is completed, another Deep stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.
Page 75
Enabling the deep stops does not disable Recommended Safety Stops. Mandatory Safety Stops, for example due to continuous ascent rate violations, are still prompted. If a deep stop is violated, it does not cause the dive computer to go into an error (Er) mode.
6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. The dive computer is easy to use and read. Each display shows only the data relevant to that specific diving mode. 6.1. Diving in the AIR mode (DIVE Air) This section contains information on diving with standard air.
6.1.1. Basic dive data During a No-decompression dive, the following information is displayed: your present depth in meters/feet • the available no-decompression time in minutes as NO DEC TIME • the ascent rate presented as a bar graph on the right side •...
It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display. The bookmarks are also shown as annotations in the downloadable Suunto DM4 software. The bookmark logs the depth, time, and water temperature, as well as compass...
To make a bookmark in the profile memory during a dive, press the SELECT button. A brief confirmation will be given. A BOOKMARK IS PLACED IN THE PROFILE MEMORY DURING A DIVE BY PRESSING THE SELECT BUTTON. 6.1.3. Tank pressure data When using the optional wireless pressure transmitter, the pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative dis- play.
Page 80
The change in your air consumption is based on constant one second interval pressure measurements over 30–60 second periods. An increase in air consumption influences the remaining air time rapidly, while a drop in air consumption increases the air time slowly.
Low Air Pressure Warnings The dive computer will warn you with two (2) audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/700 psi. Two (2) double beeps are also heard when the cylinder pressure goes down to the user-selected alarm pressure, and when the remaining time reaches zero.
DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid WARNING ascents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompres- sion model will penalize your next dive(s).
6.1.7. Decompression dives When your NO DEC TIME becomes zero, your dive changes into a decompression dive. Therefore, you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear.
Page 84
YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN WARNING DISPLAYED BY THE INSTRUMENT! The ascent time will increase if you: • remain at depth • ascend slower than 10 m/33 ft per minute or • make your decompression stop deeper than at the ceiling These factors will also increase the amount of air required to reach the surface.
Page 85
In such cases, it is more manageable to maintain an additional distance below the ceiling, to ensure that the waves do not lift you above the ceiling. Suunto recom- mends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
Page 86
Display below the floor The blinking ASC TIME sign and an upward pointing arrow indicate that you are below the floor. You should start your ascent immediately. The ceiling depth is shown on the left side, and the minimum total ascent time on the right side of the center window. Below is an example of a decompression dive without Deep Stops, below the floor.

You must not dive again for at least 48 hours (refer to Section 5.6. Error conditions). 6.2. Diving in NITROX mode (DIVE Nitrox) The NITROX mode (DIVE Nitrox) is the second dive mode available in Suunto D6i and is used when using oxygen-enriched gas mixtures.
Page 89
To set the nitrox mixes, refer to Section 5.8.1. Setting the nitrox values . Default settings In the NITROX mode, the Suunto D6i allows you to set up to three (3) nitrox mixes containing 21–99% oxygen. In the NITROX mode, the default setting for Mix1 is standard air (21% O ).

DOWN BUTTON TOGGLES BETWEEN , MAXIMUM DEPTH CURRENT TIME AND TANK PRESSURE. UP BUTTON TOGGLES BETWEEN , OLF%, DIVE TIME AND WATER TEMPERATURE. 6.2.3. Oxygen limit fraction (OLF%) If set to the NITROX mode, in addition to tracking the diver's exposure to nitrogen, the instrument tracks the exposure to oxygen.
6.2.4. Gas change and multiple breathing gas mixes One of the special features in Suunto D6i is the possibility to set two additional nitrox mixes to be used during a dive. This feature can be activated by setting the Mix2 and Mix3 as a Primary (or Secondary) gas, and entering other parameters in the same way as with the Mix1 gas.
If no button is pressed in 15 seconds, the dive computer will NOTE go back to the dive display without changing the gas mix. Upon ascent, the computer prompts you to change gas when the PO level you have set for the next mix allows a gas change.
There is no ascent rate monitoring in the GAUGE mode. NOTE If you dive with the GAUGE mode, it is not possible to change NOTE between the modes before the no fly time has counted down. In GAUGE mode, the no-fly time is always 48 hours. 6.4.
The FREE mode does not provide decompression information. NOTE There is no ascent rate monitoring in the FREE mode. NOTE 6.4.1. Day History The Day History function shows the free dive history of your latest diving day. In the SURFACE mode you can enter the Day History by pressing the SELECT button. The Day History function shows the average depth of all dives, the deepest depth of the day as well as the time, the longest dive, and the cumulative dive time in hours and minutes, as well as the number of dives made during the day.
6.4.2. Free dive time limit The FREE mode has a time limit of 10 minutes. After 10 minutes, Suunto D6i will automatically change from Free Dive to Scuba Bottom Timer (GAUGE). After the dive, the no-fly time will countdown from 48 hours. Also, you will not be able to dive in AIR or NITROX modes until the no-fly time has counted down to zero.
7. AFTER DIVING Once back at the surface, Suunto D6i continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety. Table 7.1. Alarms Symbol on display Indication Diver Attention Symbol - Extend Surface Interval...
Or, in the alternative displays, the following information will be shown: maximum depth of last dive in meters/feet • • dive time of last dive in minutes, shown as DIVE TIME the current time, shown as TIME • • the current temperature in °C/°F cylinder pressure in bar/psi (if enabled) •...
7.3. Repetitive dive planning The Suunto D6i includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual nitrogen loading of previous dives into consideration.
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.
Page 101
By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3 m/10 ft increments ending at 45 m/150 ft. No-decompression limits longer than 99 minutes are displayed as “—“. During a dive series (between two consecutive dives) it is also possible to enter the surface interval time as a planning parameter. If the % is too high for the planned depth, NA is displayed instead of a numerical no-de- compression limit.
any calculated residual nitrogen • all dive history for the past four days • The no-decompression times given for different depths will therefore be shorter than before your first “fresh” dive. You can exit the DIVE PLANNING mode by pressing the MODE button. The DIVE PLANNING mode is disabled in GAUGE mode and NOTE in Error mode (see Section 5.6.
7.6.1. Dive logbook (MEM Logbook) The Suunto D6i has a very sophisticated, high capacity Logbook and Profile Memory. The data is recorded in the profile memory based on the selected sample rate. Dives shorter than the recording interval are not registered (refer to Section 5.8.9.
THERE ARE THREE PAGES OF LOGBOOK DIVE INFORMATION. USE SELECT BUTTON TO SCROLL BETWEEN LOGBOOK PAGES I, II, AND III. THE DATA OF THE MOST RECENT DIVE IS SHOWN FIRST. YOU CAN SCROLL THE GRAPHICAL DIVE PROFILE ON PAGE III WITH UP BUTTON. Page I, main display maximum depth •...

It was developed in co-operation between Suunto and Bruce R. Wienke BSc, MSc, PhD. It is based on both laboratory experiments and diving data, including data from DAN.
10.2.1. Suunto RGBM adaptive decompression The Suunto RGBM algorithm adapts its predictions of both the effects of microbubble build-up and adverse dive profiles in the current dive series. It also changes these calculations according to the personal adjustment you select.
10.2.2. No-decompression limits for air The no-decompression limits displayed by the dive computer for the first dive to a single depth (see Table 10.1, No-decompression time limits for various depths (m) and Table 10.2, No-decompression time limits for various depths (ft)), are slightly more conservative than those permitted by the U.S.

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.
As a result, the allowed no-decompression-stop limits are considerably reduced. 10.3. Oxygen exposure The oxygen exposure calculations are based on currently accepted exposure time limit tables and principles. In addition to this, the dive computer uses several methods to conservatively estimate the oxygen exposure. For example: The displayed oxygen exposure calculations are raised to the next higher percent- •...

Decompression illness Any of a variety of maladies resulting either directly or indirectly from the formation of nitrogen bubbles in tissues or body fluids, as a result of inad- equately controlled decompression. Commonly called "the bends" or "DCI". Dive series A group of repetitive dives between which the dive computer indicates some nitrogen loading is present.
