M3 Operating Description
Power-up and Standby. The power switch is located on the rear panel of the M3; when switched on,
the tuner displays the hardware and software version of the M3 to be displayed for 3 seconds on Tuner
1’s VFD.
If rear panel AC switch is turned off or if the power is momentarily interrupted, all tuner modules and M3
control/status returns to its previous state.
Front Panel Locked. With any of the tuner modules in any mode, if the Tuner 1 switch is depressed
for 5 seconds, entire M3 goes into Front Panel Locked mode, i.e., all front panel controls are inhibited
except for Tuner 1 switch; all VFD indications, analog and digital audio outputs and PLM alarm
monitoring continue. Blue arrow LED adjacent to Tuner 1 switch flashes indicating Front Panel Locked
mode.
Momentary push of any front panel control causes Tuner 1 VFD to display FRONT PANEL LOCKED for
10 seconds then returning to its normal display for tuned station. Depressing the Tuner 1 switch for 5
seconds while M3 is in Front Panel Locked mode re-enbles all front panel controls and indicators, and
returns M3 and all tuner modules to normal operation. Tuner 1 VFD displays “Exiting Front Panel
Locked Mode” message during M3 state transition.
TUNER BAND Control. TUNER BAND control toggles between manual AM and FM tuning for the
selected tuner module based on the Tuner 1, 2, 3 switch selection. TUNER BAND arrow LED
illuminates when mode is active.
