Tuning Speed Button while rotating the Tuning Knob, the small vernier marks on the
Tuning Knob is changed to correspond to 5KHz steps. At the same time, the 100Hz digit is
cleared on the display to show "0".
This button will allow you to quickly OSY over a wide frequency range.
Pushing the button during tuning from 146.000MHz to 147.995MHz, and in the FM mode,
has по effect as the frequency is already changing in БКН? steps.
VFO SELECT SWITCH
The LSI іп the IC-211 contains two "VFOs" for both receiving and transmitting. The VFO's
are labeled "A" VFO and "B'' VFO, and are selectable with the VFO Select Switch. This
dual VFO system gives the IC-211 many very convenient features. Please read this section
very carefully and perform the operation several times until you are comfortable with the
system. Try the examples!
1. "A" VFO is for both transmitting and receiving and is selected by placing the VFO
Select switch in the "А" position.
The transmit and receive frequency will be cont-
rolled by "A" VFO, displayed on the LED frequency readout, and stored in "A"
memory.
2. "B" VFO is for both transmitting and receiving and is selected by placing the VFO
Select switch in the "В" position. The transmit and receive frequency will be controlled
by "B" VFO, displayed on the LED frequency readout, and stored in "B" memory.
FOR EXAMPLE:
When the set is turned ON, 144.000.0 will be displayed on the LED readout. This will occur
whether the VFO switch is in either the "A" or "В" or combination VFO position. Rotat-
ing the tuning knob clockwise will increase the frequency, and rotating the tuning knob
