OXYGEN ALARMS IN NITROX MODE
Three double beeps for 5 seconds occur, when:
• the OLF bar graph reaches 80%. The segments exceeding the 80% limit start to
blink (Fig. 3.23.)
• the OLF bar graph reaches 100%.
The blinking of the segments exceeding 80% will stop, when the OLF is not loading
anymore. At that point the PO
2
is less than 0.5 bar.
Continuous beeps for 3 minutes occur, when:
• the set oxygen partial pressure limit is exceeded. The maximum depth is replaced
with a current blinking PO
2
value. You should immediately ascend above the PO
2
depth limit (Fig. 3.23.).
WARNING WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY
ASCEND UNTIL THE WARNING STOPS BLINKING! Failure to do
so may lead to improper use, serious injury or death.
3.7. HIGH ALTITUDE DIVES AND PERSONAL ADJUSTMENT
The dive computer can be adjusted both for diving at altitude and also to increase the
conservatism of the mathematical nitrogen model.
