Alarms
All alarms are considered major since there are no field replaceable modules in the unit. All
alarms are indicated locally and immediately by the Alarm LED indicator blinking red. Once the
Alarm State has existed for 5 minutes, the Alarm LED will have a constant red indication.
Certain problems will result in the unit automatically shutting down after 5 minutes of sensed
failure. This is done by disabling the RF output stages in both the uplink and downlink signal
paths. Removing DC power from the unit for a period of 30 seconds or longer will reset the auto
shut down.
