2. Rotate the Tuning control until the desired tuning
step size appears in the display.The frequency step is
indicated as shown below.
144 MHz band
5210215220212.522525
430 MHz band
10220212.5225210
3. To complete the programming of the step size you
can press the MHz/STEP 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 fre-
quency will change when you change from one step
size to another.
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 12.5 kHz the
display would then read 439.925 MHz.
5,10,15,20 to 12.5,25 12.5,25 to 5,10,15,20
0,5,10,15 0 0 0
20,25,30,35 25 125 10
40,45,50,55 50 25 20
60,65, 70,75, 37.5 30

4-2-4. Programmable VFO Tuning Limits
The radio provides the capability of programming the
VHF or UHF 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 transceiver that you only wish to tune the 144.000
MHz and 145.000 MHz band segment by specifying any
frequency with these two segments. The Tuning con-
trols would then only tune within these specific. bands.
The procedure for specifying the bands is described be-
low.
1. Rotate the Tuning control until the desired
tuning range appears on the frequency display.
For example you might want to select the 144 MHz
band and dial up 144.100 MHz.
. Press the M key, then press the V key.
3. Rotate the Tuning control until the desired upper
tuning range appears on the frequency display.
. Press the M key, then press the A key.
5. To confirm that the programming was properly per-
formed rotate the Tuning control.
The transceiver should not go above or below the
programmed band limits.
6. To clear both programmed limits simultaneously, ini-
tialize the VFO memory (VFO RESET). You can repro-
gram either limit independently by following the ap-
propriate instructions above.
