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.).
