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 PO2 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 PO2 value. You should immediately ascend above the PO2 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.
