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 Off. During that time, the audible alarm can be acknowledged and silenced by press-
ing the SEL button. An LED Warning Light, on the lower end of the housing, is synchronized with and flashes as
the audible alarm sounds. It will turn off when the alarm is silenced. The audible and LED alarm will not be active
