a COM window, VLOC window and the GPS window (the right 3/4 of the display).

To change the standby communication frequency:
1. Press the small left knob (1) if needed, to move the tuning cursor to
the COM window
2. Rotate the large left knob (2) to select the MHz, and the small left
knob (1) to select the kHz of the desired frequency
To place the standby communication frequency in the active field, press the
COM flip-flop key (6).
