AUDIBLE ALARM

While operating in Dive or Gauge Mode, the audible alarm will emit 1 beep per second for 10 seconds when
alarms strike, unless it is set to Off. During that time, the audible alarm can be acknowledged and silenced by
pressing the SELECT button.
An LED warning light, on the side of the housing, is synchronized with the audible alarm and flashes as the au-
dible alarm sounds. It will turn off when the alarm is silenced. The audible and LED alarms will not be active if the
audible alarm is set to OFF (a Set Alarms setting).
