  • Page 16: Introduction

    1. INTRODUCTION Congratulations on your purchase of the SUUNTO D9 dive computer. The D9 builds on the Suunto tradition of delivering feature-rich dive computers and provides many new and enhanced features that cannot be found in other dive computers, such as di- gital compass, gas switching and optional wireless air-integration.
  • Page 17 • The Suunto RGBM/Deep Stop Algorithm The Suunto Reduced Gradient Bubble Model (RGBM) utilized in the D9 predicts both dissolved and free gas in blood and tissues of divers. It is a signifi cant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto RG- BM is additional safety through its ability to adapt to a variety of situations and dive profi...

  • Page 18: Safety Precautions

    Make sure that you fully understand the use, displays and limitations of the instrument. If you have any questions about the manual or the dive computer, contact your SUUNTO dealer before diving with the dive com- puter.

  • Page 19: Dive Computer Limitations

    STEP 1: Assess the situation calmly and then move promptly to less than 18 m [60 ft]. STEP 2: At 18 m [60 ft], slow down your ascent rate to 10 m/min [33 ft/min] and move to a depth between 3 and 6 meters [10 to 20 ft]. STEP 3: Stay there as long as you assess your air supply will safely allow.

  • Page 20: Freediving

    DIVING IS NOT RECOMMENDED. You should avoid freediving and not exceed fi ve meters [16 ft] for at least two hours after scuba diving. Suunto also recommends you to be trained in freediving technique and physiology be- fore conducting breathhold dives. No dive computer can replace the need for proper...

  • Page 33: Compass Settings

    4.3.2. CALIBRATE Because of changes in the surrounding magnetic fi eld the D9 electronic compass occasionally needs to be re-calibra- ted. During the calibration process the compass adjusts itself to the surrounding magnetic fi eld. As a basic rule, you should calibrate the compass when it does not seem to operate pro- perly, or after replacing the D9 battery.
  • Page 34 Strong electromagnetic fi elds, such as powerlines, loudspea- kers and magnets can affect the compass calibration. It is the- refore advisable to calibrate the compass if the D9 has been exposed to these fi elds. NOTE! It is recommended to calibrate the compass before using it at a new location.

    Reasons to perform a safety stop include a reduction in sub clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The D9 displays two different types of safety stops: Recom- Fig. 5.11. Setting Dive Ti- me Alarm. Press up/down mended Safety Stop and Mandatory Safety Stop.

Deep Stops are decompression stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation.

  • Page 46: Dive Mode Settings

    5.2. DIVE MODE SETTINGS This D9 has several User Defi nable Functions and depth and time related alarms that you can set according to your perso- nal preference. The dive mode settings are dependent on the DIVE sub-mode chosen (Air, EAN, Gauge), so that e.g. nitrox settings are only available in the DIVEean sub-mode.

  • Page 47: Dive Time Alarm

    5.2.2. DIVE TIME ALARM The instrument has one Dive Time Alarm Setting, which can be used for several purposes to add to your diving safety (Fig 5.10). The alarm can be set, for example, to your planned bot- tom time. The Dive Time alarm can be set on or off and the ti- me from 1 to 999 minutes (Fig.5.11).

    ALTITUDE DIVING The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a higher altitude, the diver will have additional nitrogen in his body, compared to the equilibrium situation at the original altitude. This “additional” nitrogen is released gra- dually in time and equilibrium is reached.

    12. GLOSSARY Air Time The amount of dive time remaining, based on a calculation of cylinder pressure and ambient pressure and present air consumption. Altitude dive A dive made at an elevation greater than 300 m [1000 ft] above sea level. Ascent rate The speed at which the diver ascends toward the surface.

The most important of which is an epileptic-like convulsion which can cause a diver to drown. CNS% Central Nervous System toxicity limit fraction.

Whole-Body Toxicity Another form of oxygen toxicity, which is caused by prolonged exposure to high oxygen partial pressures. The most common symptoms are irritation in the lungs, a burning sensation in the chest, coughing and reduction of the vital capacity.
