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.
1. Press the VFO/M^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.
For example with the TM-241 you might want to
select the 144 MHz band, and dial up 144.100 MHz.
3. Press the F key for longer than 1 second. The F
indicator should begin flashing.
4. Press the CALL key within 10 seconds. A long beep
will sound and the F indicator will turn off in the
display. This indicates that the lower limit has been
successfully stored in memory.
