Programmable Vfo Tuning Limits - Kenwood TM-241A Instruction Manual

4. Rotate the tuning control or press the UP / DWN
switches on the microphone until the desired tuning
step size appears in the display.
5. To complete the programming of the step size you
can press any key on the front panel except the
POWER key, or simply wait 10 seconds and the
microprocessor will automatically return to the
normal frequency display.
The chart below shows how the microprocessor will
correct a new step size.

5-2-4 Programmable VFO Tuning Limits
The TM-241/441/541 series radios provide the capabil-
ity of programming the VFO tuning range, in 1 MHz
band segments, as well a providing a separate program-
mable band scan function(See page 26). For example
you could tell the transceiver that you only wish to tune
the 144 MHz and 145 MHz band segments. The tuning
controls and microphone UP/DWN
switches would then
only tune within these specific frequency limits. The
procedure for specifying these limits is described below.
. Press the VFO/MP V key to select the VFO mode.
2 . Rotate the tuning control or press the microphone
UP / DWN switches until the desired lower tuning
range appears in the frequency display.
Press the key for longer than
1 second.
