- 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 MAXI-
MUM LIMIT IS REACHED, YOU MUST IMMEDIATELY ASCEND UNTIL
THE WARNING STOPS BLINKING! Failure to take action to reduce oxygen
exposure after the w arning is gi ven can rapidly increase the risk of oxygen
toxicity and the risk of 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.
3.7.1. Altitude Adjustment
When programming the instrument for the correct altitude, you need to select the
correct Altitude Mode according to Table 3.4. The dive computer will adjust its
mathematical model according to the entered altitude mode, gi ving shorter no-
decompression times at higher altitudes (see Section 6.1. “Operating Principles”,
Table 6.1. and 6.2.).
The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1
