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-300
looks for activity on each
channel.
To start Dual Watch,
press the [
F
] key mo-
mentarily, then press the
[
SCAN
(
DW
)].
The “
” icon will ap-
pear on the display.
While receiving on the
“current” channel (not the Pri-
ority channel), you may push
the
PTT
switch at any time to
transmit on that channel.
When a signal is received on the Priority channel, op-
eration immediately shifts to the Priority channel, the
“
” icon will blink, and the display will become
illuminated.
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
]
[
SCAN
(
DW
)].
If you wish, you may use both the Dual Watch and
Scan features simultaneously. To do this, start the Dual
Watch first, then start the Scanner.
: The “priority” Channel is defined as the
last-used
Memory Channel
(when using the VFO mode) or
Memory
Channel 1
(when using the Main Memory or Book Memory
modes).
