Working with alarms
When an alarm is muted, the Alarm mute key LED will light constantly. If after two minutes the
problem is still present, the alarm will sound again for high or medium priority alarms except for the
Internal Battery Low (30%) alarm. This alarm will be permanently muted with both the audible signal
and alarm message cleared. However, these indicators will initiate again when the Internal Battery
Empty (2 minutes remaining) alarm is activated.
