OXYGEN ALARMS IN NITROX MODE
Continuous beeps for 3 minutes activated backlight, when:
- the set oxygen partial pressure limit is exceeded. The alternative display is
replaced with a current blinking PO
2
value. You should immediately ascend
above the PO
2
depth limit (Fig. 6.17-6.18.).
- the OLF value reaches 80%. The OLF value will start to blink.
- the OLF value reaches 100%. The OLF value will blink.
NOTE! When the backlight is turned OFF, it does not illuminate when an alarm is ac-
tivated.
WARNING!
WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE MAXIMUM LIMIT
IS REACHED, YOU MUST IMMEDIATELY ASCEND UNTIL THE WARNING STOPS
BLINKING! Failure to take action to reduce oxygen exposure after the warning is gi-
ven can rapidly increase the risk of oxygen toxicity and the risk of injury or death.
6.7. ERROR CONDITIONS
The dive computer has warning indicators that alert the user to react to certain situa-
tions that would signifi cantly increase the risk of DCI. If you do not respond to its war-
nings, the dive computer will enter an Error Mode, indicating that the risk of DCI has
greatly increased. If you understand and operate the dive computer sensibly, it is very
unlikely you will ever put the instrument into the Error Mode.
