Basic Operations
VFO mode
VFO tuning is set as the default mode at the factory. VFO
(variable frequency oscillator) allows you to change the fre-
quency in accordance with the selected channel step as you
rotate the main dial or by using the UP/DOWN keys on the
microphone. VFO mode is also used to program the data to
be stored in the memory channels or to change the parameter
settings of the transceiver.
1. Identify the current mode by checking the dis-
play. If a “M” or “C” icon is NOT displayed
on it, the unit is already in the VFO mode.
If memories have not been programmed, the
unit cannot be switched to the memory mode.
2. Otherwise press “V/M” key until those icons
are gone.
Changing frequency by channel step
Rotate the main dial clockwise to increase the frequency, coun-
terclockwise to decrease. The UP/DOWN keys on the micro-
phone act in the same way.
Changing frequency by 1 MHz step
This will enable a quick change of frequency in 1 MHz steps:
1. Press MHz key. The digits after 100 kHz will
disappear from the display.
2. Follow the same sequence as above to change
the value.
