Suunto D9 Watch User Manual

1. SUUNTO When traveling overseas it is recommended that you recalibrate the compass at the new location before using it Remember to hold the Suunto D9 level during the calibration SUUNTO 31 If the calibration fails several times in a row it is possible that you are in an area with sources of magnetism such as large metal objects powerlines or electric appliances Move to another location and try to calibrate the compass again If the calibration continues to fail contact an authorized Suunto service center 32 5 BEFORE DIVING Do not attempt to use the dive computer without reading this user s manual in its entirety including all the warnings Make sure that you fully understand the use displays and limitations of the instrument If you have any questions about the manual or the Suunto D9 please contact your Suunto representative before diving with the dive computer Always remember that YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY When used properly Suunto D9 is an outstanding tool for assisting properly trained certified divers in planning and executing sport dives It is NOT A SUBSTITUTE FOR CERTIFIED SCUBA INSTRUCTION including training in the principles of decompression WARNING Diving with enriched air mixtures nitrox exposes you to risks that are different from those associated with diving with standard air These risks are not obvious and require training to understand and avoid Risks include possible serio
2. DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND ENTERED THE ANALYZED VALUE INTO YOUR DIVE COMPUTER Failure to verify cylinder contents and enter the appropriate O into your dive computer will result in incorrect dive planning information THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL 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 you want to adjust the computer to provide more conservative calculations use the personal adjustment feature to affect decompression calculations or reduce the PO setting to affect oxygen exposure SELECT THE CORRECT ALTITUDE ADJUSTMENT SETTING When diving at altitudes greater than 300 m 1 000 ft the Altitude Adjustment feature must be correctly selected in order for the computer to calculate the decompression status The dive computer is not intended for use at altitudes greater than 3 000 m 10 000 ft Failure to select the correct Altitude Adjustment setting or diving above the maximum altitude limit will result in erroneous dive and planning data WARNING WARNING NOTE SELECT THE CORRECT PERSONAL ADJUSTMENT SETTING 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

GBM is a modern algorithm for predicting both dissolved and free gas in the tissues and blood of divers 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 It is a significant advance on the classical Haldane models which do not predict free gas microbubbles The advantage of Suunto RGBM is additional safety through its ability to adapt to a wide variety of situations Suunto RGBM addresses 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 103 9 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 The pattern and speed of decompression at the surface is adjusted according to microbubble influence On repetitive dives adjustment may also be applied to the maximum allowable nitrogen overpressure in each theoretical tissue group Depending on the circumstances Suunto RGBM will adapt the decompression
