Continuous beeps for 3 minutes and the backlight activated occur when:
• the set oxygen partial pressure limit is exceeded. The maximum depth is
replaced with the 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 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 given can rapidly
increase the risk of oxygen toxicity and the risk of injury or death.
