Selecting Programmable Switch Functions
The programmable switch on the top panel can be con-
figured using the menu to provide several functions:
• Power - turns the power on and off
• Mute - mutes the audio when switched on
• TalkBk (talkback) - redirects the audio to a different
output channel on the receiver (with receivers that
offer this function)
• (none) - disables the switch

Main Window Indicators
The Main Window displays the band number, Standby
or Operating mode, operating frequency, audio level,
battery status and programmable switch function. 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
increased by 25

example.

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.
