DUAL WATCH FEATURES
If a signal appears on the selected channel
Scanning will pause on the selected channel but channel 16 will continue to be monitored every
2 seconds resulting in short breaks in the reception of the selected channel. During this time the
PTT
may be pressed for normal transmissions on the selected channel (monitoring of channel
16 pauses while transmitting). Once the selected channel has become inactive for 5 seconds the
Dual Watch function will resume.
If a signal appears on channel 16
The radio will switch immediately to channel 16 and the selected channel will no longer be
monitored because channel 16 has priority. During this time the
PTT
may be pressed for normal
transmissions on channel 16. Once channel 16 has become inactive for 5 seconds the Dual
Watch function will resume.
To transmit on the selected channel while Dual Watching
Simply press the
PTT
. The Dual Watch function will pause and the radio will transmit on the
selected channel. Dual Watch will then resume 5 seconds after all activity has ceased on the
channel.
To transmit on channel 16 while Dual Watching
Press the
16
key to switch to channel 16. Dual Watch will be cancelled and the radio will
switch straight to channel 16 and the ‘SAFETY’ icon will be displayed. Now press the
PTT
and
transmit in the usual way. When your conversation has ended, press the
DW
key to resume Dual
Watching.
To change the working channel while Dual Watching

automatically continues using the newly selected channel.
TRIPLE WATCH KEY (TW)
Triple Watch is an extension of the Dual Watch feature. It allows the GX750 to monitor channel
16, a selected working channel AND the PR1 channel memory. Each channel is scanned equally
for signals with priority given first to channel 16, then the PR1 channel and lastly the selected
channel.
