6. Programmable VFO Tuning Limits
This radio provides the capability of programming the
VFO tuning range, in 1 MHz band segments, as well a
providing a separate programmable band scan function.
(See page 41.)
The procedure for specifying the bands is described
below.
1. Press the BAND SEL key to select the desired band.
2. Rotate the Tuning control until the desired lower
tuning range appears on the frequency display.
For example, you might want to select the 438 MHz
band and dial up 438.100 MHz.
3. Press and hold the F key, then press the CALL key.
4. Rotate the Tuning control until the desired upper
tuning range appears on the frequency display.
5. Press and hold the F key, then press the SHIFT key.
To cancel the programmable VFO function for each
band, switch the power off, hold down the VFO key
and the VOL control for that band, then switch the
power on.
To cancel the programmable VFO function for both
bands, switch the power off, and hold down the VFO
key, and switch the power on.
7. Frequency Step Selection
To select the desired tuning or scan step size use the
following procedure:
1. Press the BAND SEL key to select the desired band.
2. Press the F key momentarily. The F indicator should
light on the display.
3. Press the REV/STEP key within 10 seconds of
pressing the F key. The current frequency step size
will be displayed.
4. Rotate the Tuning control or press the microphone
UP/DWN keys until the desired tuning step size
appears in the display.
5. To complete the programming of the step size you
can press any front panel key or simply wait 10
seconds and the microprocessor will automatically
return to the normal frequency display.
The chart below illustrates the way
the displayed
frequency will change when you change from one step
size to another.

If you were to change the step size to
12.5 kHz the display would then read
439.925 MHz.
