FREQUENCY AND CHANNEL SETTING
■ VFO and memory channels
This receiver has 2 normal operating modes:VFO mode and
memory mode.
VFO mode is used for setting a desired frequency within the
frequency coverage.
➥Push [V/M] to select VFO mode.
Memory mode is used for operation of memory channels
which have programmed frequencies.
➥Push [V/M] to select memory
mode.
•To program a memory, refer to p. 12.
What is VFO?
VFO is an abbreviation of Variable Frequency Oscillator. Fre-
quencies for receiving are generated and controlled by the
VFO.
■ Operating band selection
The receiver can receive
the broadcast band, HF
band, 50 MHz band, VHF
avionics band, 144 MHz
band, 300 MHz band, 400
MHz band, 800 MHz band*
or 1200 MHz band.
➥Push [BAND] several
times to select the de-
sired band.
•When a memory channel
is selected, the first push
of [BAND] selects VFO
mode (and transfers the
memory channel con-
tents).
➥Rotate [DIAL] while
pushing [BAND] to select
the desired band.
*Some frequencies can-
not be received with
the U.S.A.version.
