Dual Watch Operation - Vertex Standard Pilot III Operating Manual

The Dual Watch feature automatically checks for activity
on a "priority" channel while you are operating on an-

channel and the Priority channel will each be polled for a
500 ms interval, as the VXA-300 looks for activity on each
channel.

" " icon will blink, and the display will become
illuminated.

tarily press the PTT switch, Dual Watch will be dis-
abled. You may then transmit on the Priority Channel.
