In 12.5 kHz ,or 25kHz step size, direct frequency
selection will be completed in the 1 0 kHz digit. When
you enter the following keys for the 1 0 kHz digit. 1 kHz
and 1 00 Hz digit frequencies are automatically selected
the list below.

4-2-3. Step Size Selection
To select the desired tuning or scan step size use the
following procedure:
1. Press the F key momentarily, then press the
MHz/STEP key. The current frequency step size will
be displayed.

( MHZ )
2. Rotate the Tuning control until the desired tuning step
size appears in the display.The frequency step is
indicated in the chart below.
5±:;10i=>1 5i:>20±^12.5:^25±^5
3. To complete the programming of the step size you can
press the MHz/STEP key.
The chart below illustrates the way the displayed frequency will change
when you change from one step size to another.
5,10,15,20 to 12.5,25 12.5,25 to 5,10,15,20
0,5,10,15 0

For example:
Assume you are presently displaying a frequency of 439.920 MHz and
had previously selected a 20 kHz step size. If you were to change the
step size to 1 2.5 kHz the display would then read 439.925 MHz.
4-2-4. Programmable VFO Tuning Limits
The radio provide the capability of programming the VFO
tuning range, in 1 MHz band segments, as well a
providing a separate programmable band scan function.
(See section 4-5.) For example you could tell the trans­
ceiver that you only wish to tune the 1 44.000 MHz and
