TRIPLE WATCH (CB MODE)

The Triple Watch function is an extension of the Dual Watch feature. It allows the GX400 to 
monitor three channels – Channel 8, a selected channel and a Priority channel. Each channel is 
scanned equally for signals with priority given first to Channel 8, then the Priority channel and 
lastly the selected channel.

When Triple Watch is selected, the ‘TW’ icon is displayed. The Priority channel used is the one 
stored in the PR1 memory.

To use the Triple Watch mode, first program your Priority channel into the PR1 memory then 
select your preferred working channel using the   or   keys. Now briefly press the 

TW

 key. 

A high beep will be heard, ‘TW’ will appear and the channel display will alternate between 
Channel 8, your selected channel and your Priority channel. 

To cancel Triple Watch

Briefly press the 

TW

 key. A low beep will be heard and ‘TW’ will disappear from the display.

TRIPLE WATCH FEATURES
If a signal appears on Channel 8

The radio will switch immediately to Channel 8. At this point the selected channel and the PR1 
channel are no longer being monitored because Channel 8 has highest priority. During this time 
the 

PTT

 may be pressed for normal transmissions on Channel 8.

Once Channel 8 has become inactive for 2 seconds the Triple Watch function will resume.

If a signal appears on the PR1 channel

Scanning will pause on the PR1 channel 

but

 Channel 8 will continue to be monitored (the 

selected channel is not monitored). During this time the 

PTT

 may be pressed for normal 

transmissions on the PR1 channel (monitoring of Channel 8 ceases while transmitting). 

Once the PR1 channel has become inactive for 2 seconds Triple Watch will resume. 

If a signal appears on the selected channel

Scanning will pause on the selected channel 

but

 Channel 8 

and

 the PR1 channel will continue 

to be monitored. During this time the 

PTT

 may be pressed for normal transmissions on the 

selected channel (monitoring of Channel 8 and the Priority channel ceases while transmitting). 
Once the selected channel has become inactive for 2 seconds the Triple Watch will resume.

To transmit on the selected channel while Triple Watching

Simply press the

 PTT.

 The Triple Watch function will pause during the transmission and remain 

paused until 2 seconds after all activity has ceased on the channel. Triple Watch will then resume.

To transmit on the Priority channel while Triple Watching 

Briefly press the 

PR1

 key. The PR1 channel will then become the selected channel. Now press 

the 

PTT

 and transmit in the usual way. When your conversation has ended you may use the  

 or   keys to re-select your preferred channel.
