The defaulted hand microphone voice gain value can meet the demand of
voice communication in most cases. In case of superfluous spectral lines with
relatively low magnitude on both sides of voice spectral lines displayed on the
screen, the hand microphone voice gain value can be appropriately adjusted till
superfluous spectral lines disappear.

The voice-control transmission VOX can automatically judge whether there is
hand microphone voice signal or line input signal, so as to automatically control
the radio to switch between the receiving and transmission. After the VOX
function is activated, it is unnecessary to press the hand microphone PTT key to
start the transmission.
After pressing [FUNC] key to activate the second function, press the volume
knob in a short time to enter the VOX function setting option and circularly press
the volume knob in a short time to switch menus.

When the AFIN port of the ACC interface is used for line input voice control, set the appropriate input
volume in the "AUX IN Volum" option in the system menu.
