(MonitorAlarmsReceive) – RECEIVE ALARMS

Rx Traffic: AGC Alarm -	(ENT)
Reduce Input level

The screen will indicate if there are any Receive Traffic Faults. If not, it will display ‘None’. Pressing ENT takes the user back to the previous menu.

(MonitorAlarmsTransmit) - TRANSMIT ALARMS

Tx Traffic: No Tx	Clock
From Terrestrial	(ENT)

The screen will indicate if there are any Transmit Traffic Faults. If not, it will display ‘None’. Pressing ENT takes the user back to the previous menu.

(MonitorAlarmsODU) – OUTDOOR UNIT ALARMS

The screen will indicate if there are any ODU Alarms. If not, it will display ‘None’. Pressing ENT takes the user back to the previous menu.
