3) Press any key except the POWER, LAMP, and MONI keys.
The displayed step size is set, and the normal frequency display returns.
Changes in the Displayed Frequency
As you change from one step size to another, the displayed frequency also changes, as illustrated in the
accompanying charts.
For example, assume you are presently displaying 439.920 MHz at a 20 kHz step size. If you were to change
the step size to 12.5 kHz, the display would read 439.925 MHz.

Programmable VFO Tuning Limits

This radio provides the capability of programming the VFO tuning range, in 1 MHz band segments, as well as
providing a separate programmable band scan function. (See page 21).
For example, you could tell the transceiver that you only wish to tune the 144.000 MHz and 145.000 MHz band
segments by specifying any frequency within these two segments.
The Tuning control would then only tune within these specific bands. The procedure for specifying then bands is
described below.
1) Select the desired lower tuning limit. For example, you might want to select the 144 MHz band and dial up
144.100 MHz.
2) Press and hold the M key for longer than one second, then press the 1 key. This selects the lower frequency
limit for the programmable VFO.
