8.3 Alarm monitoring with the STATUS HIST command
Check alarms with ‘status hist‘ command.
1.  If a hardware module is damaged, replace corresponding hardware module.
2.  Minor alarms with no influence on the system can be cancelled by confirming the alarm
with the ‘alarmackn’ command, e.g., ALC active, VSWR, RSSI or DOOR OPEN.
3.  If all alarms have been acknowledged the summary error LEDs will be set back to green
indication.
4.  In case of mains power failure the contents of the actual STATUS HIST list is lost.
For a complete list of available alarms, see table 3-4 List of all available alarms
8.4 Power supply
The output voltage is factory set and should not be changed.
8.5 General remarks
 After a software download previous user settings ( data default values ) might be
overwritten. Before you start a software download save the set values for:
centre frequency
attenuation
ALC threshold
 If an ALC or AMPBIAS alarm occurs during installation or commissioning an user error
might be the cause, due to wrong measurements.
