Tri-Watch

Tri-Watch gives you one (1) button access to scan the three (3) locations of most
importance to you. Channel 16 and Channel 9 will always be included as scanned
locations. The remaining location will be the VHF channel in effect when you enter 
Tri-Watch mode.

NOTE
The radio must be squelched for tri-watch to function. See page 36
for squelch procedure.

To Enter Tri-Watch Mode:

1. In Standby mode, use the Up/Down buttons to go 

to the channel you want to add as the third location 
to be scanned.

2. Press the Tri-Watch button.

Tri-watch will be indicated on the LCD and the radio 
will scan among Channel 16, Channel 9, and the third 
tri-watch location you selected. A signal on any one (1) 
of the three (3) channels will stop the scan to allow you
to listen to the traffic on the channel. The channel 
number will be displayed on the LCD.

To Exit Tri-Watch Mode:

1. Press the Tri-Watch button. The radio will 

return to Standby mode.

During Tri-Watch (while receiving an incoming
transmission), You Can Choose From The Following:

tri-watch location and return to Standby mode.

b. Press the Up/Down buttons to resume scanning 

tri-watch locations.

If you do not press any buttons, your radio will
automatically resume scanning tri-watch locations 
when the incoming transmission is complete.

tri-watch location scanned and return to Standby mode.
