Suunto VYTEC DS manual

WARNING!

THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PER- CENTAGE 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 calcu- lations. If there is a desire to adjust the computer to provide more conservative calculations, use the personal adjustment feature to af- fect decompression calculations or reduce the PO2 setting to affect oxygen exposure.

WARNING!

SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When diving at altitudes greater than 300 m [1000 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 3000 m [10000 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!

SET THE CORRECT PERSONAL ADJUSTMENT MODE! When- ever 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.

NOTE!

It is not possible to change between Air, Nitrox and Gauge modes before the instrument has counted down the no-flying time.

There is one exception to this: You can change from Air to Nitrox mode even during the no-flying time. 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.

In Gauge mode, the no-flying time is always 48 hours.
