You are able to preset alarms before the actual dive. The user programmable 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.
