PERATION
The Dual Watch feature automatically checks for activity
on a “priority” channel
while you are operating on an-
other channel. During Dual Watch operation, the current
channel and the Priority channel will each be polled for a
500 ms interval, as the
VXA-220 looks for activity on
each channel.
To start Dual Watch,
press the [
F
] key fol-
lowed by the [ 6
(
DW
)]
key. The “ DW ” icon
will appear on the dis-
play.
While receiving on the
“current” channel (not the
Priority channel), you may
push the
PTT switch at any
time to transmit on that
channel.
When a signal is received on the Priority channel,
operation immediately shifts to the Priority channel,
the “
DW
” icon will blink, and the display will be-
come illuminated unless the Scan Lamp Feature is
turned off.
While receiving on the priority channel, if you momen-
tarily press the
PTT
switch, Dual Watch will be dis-
abled. You may then transmit on the Priority Channel.
To stop Dual Watch, press [ F
] key followed by the
[
6
(
DW
)] key.
: The “priority” Channel is defined as the last-used
Memory Channel (when using the VFO mode) or
Memory Channel “001” (when using the Main
Memory or Book Memory modes).
