23"
Front panel of the tuner is locked whenever alarm is armed to prevent false alarm conditions.
De-activate Alarm - To de-activate the configured alarm functions, press the CLEAR ALARMS button
for 5 seconds. Tuner VFD display returns to normal operation and front panel of the tuner is unlocked.
Alarm Notification and Reset - When any alarm is active, audible alarm will sound (modulated
beeping, if Alarm Buzzer has been set to “ON”) and second line of VFD will scroll an alarm message
indicating “ALARM” and the specific alarm that is active, for example “ALARM – RF CARRIER LOSS,
PRESS SELECT TO CLEAR”. Pressing the CLEAR ALARM button will clear all alarms.
If during an alarm-active condition the alarm condition is corrected, the tuner will reset to its state before
the alarm occurred and the audible alarm will cease. The tuner alarms as configured will remain active
until de-activated by the user, as described above.
