Summary of Attention Messages and Alarms

The Monitor 3 Air draws your attention to certain situa- tions and warns you of unsafe diving practices. Attention messages and alarms are always visual and acoustical while underwater; they are only optical at the surface except for the decompression alarm.

Attention Messages

Attention messages are given by symbols, letters, or flashing figures. In addition, two short beeps can be heard, in intervals of 4 seconds, in two different frequencies. Attention messages appear in the following situations:

Altitude dive

During a change to a higher altitude, the Monitor 3 Air displays an altitude sector icon and the corresponding adapta- tion time.

End of no-stop time

To avoid making a decompression dive, a "0" flashes during the last minute of no-stop time to alert you to ascend to a shallower depth. Also, two beeps are sounded.

Air Time Remaining is less than 3 minutes

To avoid a potential out-of air situation, immediately begin your ascent.
