You are able to preset alarms before the actual dive. The user program-
mable alarms can be set for maximum depth, dive time and time. The
alarms activate when:
• The preset maximum depth is reached
• continuous beep series for 24 seconds or until any button is
pressed.
• the maximum depth blinks as long as the present depth value
exceeds the adjusted value.
• The preset dive time is reached
• continuous beep series for 24 seconds or until any button is
pressed.
• the dive time blinks for one minute, if no button is pressed.
• The preset alarm time is reached
• the current time is shown.
• continuous beep series for 24 seconds or until any button is
pressed.
• the current time blinks for one minute, if no button is pressed.
OXYGEN ALARMS IN NITROX MODE
Three double beeps and the backlight activated for 5 seconds
occur, when:
• the OLF bar graph reaches 80%. The segments exceeding the
80% limit start to blink (Fig. 3.24.)
• 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 and the backlight activated
for 5 seconds 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. 3.24.).
NOTE! When the backlight is turned OFF, it does not illuminate when an
alarm is activated.
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 warning is given can rapidly increase the
risk of oxygen toxicity and the risk of injury or death.
