Push “SELECT” to continue. The alarm configuration settings are saved in non-volatile
memory.
Activate Alarm - Activate alarm conditions saved in configuration by momentarily pressing ALARM SET
button to enter ALARM CONFIG menu and selecting “ENABLE” using UP and DN switches to toggle the
setting. M2A-FM front panel is locked whenever alarm is armed to prevent false alarm conditions.
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”. Holding ALARM SET button for 5 seconds will clear all alarms.
If during an alarm active condition, the alarm condition is corrected, the M2A-FM will reset to its state before
the alarm occurred and the audible alarm will cease. The alarms as configured will remain active until de-
activated by the user.
De-activate Alarm - To de-activate the configured alarm functions, hold ALARM SET button in for 5
seconds. Monitor VFD display returns to normal operation and front panel of the monitor is un-locked.
PANEL LOCK – When PANEL LOCK switch is momentarily pressed, M2A-FM goes into Front Panel
Locked mode; i.e., all front panel controls are inhibited except for PANEL LOCK switch; analog and digital
audio outputs continue. VFD alternates between displaying FRONT PANEL LOCKED and normal display
for tuned station. Blue arrow LED illuminates only when switch is being pushed or when mode is active.
Holding PANEL LOCK switch for 5 seconds un-blanks all front panel controls and indicators, and returns
M2A-FM to normal operation. VFD displays “Exiting Front Panel Locked Mode” message during monitor
state transition.
DATA - DISPLAY – Front panel DATA-DISPLAY switch selects decoded RBDS PI (Program Identification-
station call sign) and RT (Radio Text) fields for display on the second line of the VFD. Momentary push of
DATA - DISPLAY switch alternates display between PS and RT data fields. Holding DATA - DISPLAY
switch in for 5 seconds activates DATA - DISPLAY menu. The firmware version, e.g., “v2.0.9 A3.2.1” is
displayed for 5 seconds before displaying the first menu option. The menu’s first selection enables or
disables “Scrolling Data” mode when tuner displays the RBDS PS data field for approximately 5 seconds
before scrolling to the RT field. UP or DN switches toggle the setting; pressing “SELECT” saves the setting
and scrolls the menu to the next field. The second menu field enables or disables “Audio Muting” that
automatically mutes M2A-FM’s audio outputs for received signals with signal strength less than 45dBf. Next
press of “SELECT” saves the setting and exits the menu. Blue LED illuminates only when mode is active.
Default is PS - station short name to be displayed in second line of VFD.
AUDIO PEAK – Red LED indicator illuminates when M2A-FM demodulated audio level has averaged more
than +5dB for more than 30 seconds.
ALARM – Red LED indicator blinks when there is an active alarm condition.
