Main Window Indicators
The Main Window displays the band number, Stand-
by or Operating mode, operating frequency, audio
level, battery status and programmable switch func-
tion. When the frequency step size is set at 100 kHz,
the LCD will look like the following.

When the frequency step size is set to 25 kHz, the
hex number is smaller and may include a fraction.
Note that the
frequency has

Changing the step size never changes the frequency.
It only changes the way the user interface works.
If the frequency is set to a fractional increment
between even 100 kHz steps and the step size is
changed to 100 kHz, the hex code will be replaced by
two asterisks on the main screen and the frequency
screen.
