AUXILIARY FUNCTIONS
BEAT SHIFT
Since the transceiver uses a microprocessor to control
various functions of the transceiver, the CPU clock
oscillator's harmonics or image may appear on some
spots of the reception frequencies. In this case, turn the
Beat Shift function ON.
1 Press [F], [MENU] and turn the Tuning control to
select Menu No. 25 (BS).
2 Press [MENU] and turn the Tuning control to select
"ON" or "OFF" (default).
3 Press [MENU] to store the setting or any other key to
cancel.
4 Press any key other than [MENU] to exit Menu Mode.
S-METER SQUELCH
S-meter Squelch causes the squelch to open only when
a signal with a strength greater than or the same as the
S-meter setting is received. This function relieves you
from constantly resetting the squelch when receiving
weak stations you have no interest in.
