FREQUENCY SETTING
■ VFO description
VFO is an abbreviation of Variable Frequency Oscilla-
tor, and traditionally refers to an oscillator.
The transceiver’s VFO is somewhat different. The VFO
of the IC-756 acts like a computer’s window and can
show one frequency and one operating mode.
You can call up a desired frequency to the VFO with
the keypad, memo pad-read switch (see p. 46) or the
memory transfer function (see p. 44). You can also
change the frequency with the tuning dial and select
the operating mode with the mode switches.
During dualwatch or split frequency operation, the sub
VFO is functional (non-outline, larger frequency char-
acters). While pushing [XFC] during split frequency op-
eration, you can change the transmit readout fre-
quency with the keypad, memo pad-read switch or the
memory transfer function.

VFO MODE
VFO shows a frequency and operating mode. If the
frequency or operating mode is changed, the VFO au-
tomatically memorizes the new frequency or new op-
erating mode.
When a VFO is selected from another band or mem-
ory mode, the last used frequency and operating
mode for that VFO appear.
[EXAMPLE]
MEMORY MODE (pgs. 41–45)
Each memory channel shows a frequency and oper-
ating mode like a VFO. Even if the frequency or mode
is changed, the memory channel does not memorize
the new frequency or operating mode.
When the memory channel is selected from another
memory channel or VFO mode, the memorized fre-
quency and operating mode appear.
