    1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS Suunto D6i wristop dive computer is designed to help you get the most out of your diving. With integrated digital compass and gas switching, Suunto D6i simplifies your diving experience because all the information you need relating to depth, time, decompression status, optional tank pressure, and direction is available on one easy-to-read screen.

  • Page 8: Warnings, Cautions, And Notes

    Before you go on to read the user's guide itself, it is extremely important that you read the following warnings. These warnings are intended to maximize your safety while using Suunto D6i and must not be ignored. YOU MUST READ the leaflet and user guide for your dive com- WARNING puter.
  • Page 9 (DCI). Therefore, Suunto strongly recommends that the device not be used for any commercial or professional diving activities. ONLY DIVERS TRAINED IN PROPER USE OF SCUBA DIVING...
  • Page 10 SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS WARNING LIMIT THEIR MAXIMUM DEPTH TO 40 M/130 FT OR TO THE DEPTH CALCULATED BY THE COMPUTER BASED ON THE SELECTED O % AND A MAXIMUM PO OF 1.4 BAR! Exposure to greater depths increases the risk of oxygen toxicity and decom- pression illness.
  • Page 11 YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COM- WARNING PUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIV- ATE 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. Review the recommendations given by Divers Alert Network (DAN).
  • Page 12 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 decompres- sion calculations.
  • Page 13 SET THE CORRECT PERSONAL ADJUSTMENT MODE! WARNING Whenever it is believed that factors that tend to increase the possibility of DCI exist, it is recommended that you use this option to make the calculations more conservative. Failure to select the correct Personal Adjustment setting will result in erroneous dive and planning data.
  • Page 14 NEVER ASCEND ABOVE THE CEILING! You must not ascend WARNING above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling. DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU WARNING HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND ENTERED THE ANALYSIS VALUE INTO YOUR DIVE COM-...
  • Page 15 Suunto also recommends that you receive training in Free diving WARNING techniques and physiology before conducting breath hold dives.
  • Page 16 Using the Suunto Dive Planner software is not a substitute for WARNING proper dive training. Diving with mixed gases has dangers that are not familiar to divers diving with air.

  • Page 32: Compass Settings

    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 33 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 recalibrate NOTE the compass at the new location before using it.
  • Page 34 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.
  • Page 35 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 37: Emergency Ascents

    The Suunto D6i allows you to choose between a traditional Recommended Safety Stop and Deep Stops. Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation. In order to optimize the response to different increased risk situations, an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced.

  • Page 38: Dive Computer Limitations

    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.

  • Page 39: Audible And Visual Alarms

    Suunto also 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.

  • Page 63: Diving At Altitude

    5.9.4. Diving at altitude The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model. When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.6, Altitude Adjustment settings. The dive computer will adjust its mathematical model according to the entered altitude setting, giving shorter no-decompression times at higher altitudes.

  • Page 64: Personal Adjustments

    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 65 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.

  • Page 66: Safety Stops

    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.

  • Page 67: Mandatory Safety Stops

    (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.

  • Page 68: Deep Stops

    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 69 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.

    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 with Movescount software. The bookmark logs the depth, time, and water temperature, as well as compass heading (if the compass has been enabled).

  • Page 73: Tank Pressure Data

    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 74 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.

  • Page 75: Ascent Rate Indicator

    Three (3) double beeps are also heard when the cylinder pressure goes down to the user-selected alarm pressure, and when the remaining time reaches zero. 6.1.4. Ascent rate indicator The ascent rate is displayed graphically along the right hand side with a vertical bar. When the maximum allowed ascent rate is exceeded, the lower segment of the bar starts to blink with the top segment staying solid, indicating that the maximum ascent rate has been exceeded.

  • Page 76: Safety Stops

    6.1.5. Safety Stops A three (3) minute Recommended Safety Stop is prompted after every dive to over 10 m. 6.1.6.

    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.

  • Page 92: Dive Planning Mode (Plan Nodec)

    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 93 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.

    10.2.3. 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.
