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 PO
2
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-fl ying time.
There is one exception to this: You can change from Air to Nitrox mode
even during the no-fl ying 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-fl ying time is always 48 hours.
