Identifying an alarm
The best way to identify an alarm is by viewing the front panel’s
Transmitter Status
page
( Figure 1.1 ). If an alarm exists, the
Status
button at the bottom of the AUI display will be red. Press
or click the
Status
button to go to the
Transmitter Status
page.

1. View the list of active faults by pressing the
Alarms
tab. Alarms are listed by their origin
(
Device
column), then by name (
Alarm
column), and then by severity [a single yellow !
indicates low severity (RF output not affected), a single orange ! indicates medium severity
(RF output is reduced), two red ! indicates high severity (RF output is inhibited); see
Level
column]. See “List of current alarms” on page 1-5 .
2. Attempt to clear any latching alarms by pressing the
Reset
button on the bottom banner of
the page. If the alarm persists, it will not be cleared from the display.
3. Refer to Table 1.1 on page 1-6 for troubleshooting tips on the offending alarm(s), which may
also reference replacement and subsequent re-calibration procedures. Note the origin of the
alarm (i.e., contained within Controller, Exciter, Rack # or Module # sub-system folders).
