Chapter 1: Operation 13
Actions to take if an alarm occurs
If an alarm occurs, investigate the cause immediately and if possible, take
appropriate action to remove the cause. If an alarm message is displayed, use this
to guide your course of action.
Silencing internal alarms
You can silence an internal alarm by pressing any one of the ST60+ Graphic
Display front panel buttons. Remember though, that removing the alarm sound
does not remove the cause of an alarm. If the alarm condition persists, the alarm
will recur.
Silencing external alarms
Most external alarms can be silenced only at the alarm-initiating device
e.g. autopilot, GPS or master instrument. Exceptions to this are the LOST FIX
ALARM and the LOW BATTERY ALARM , which can be silenced by
pressing any of the ST60+ Graphic Display front panel buttons.
