Your radio may be able to operate on a P25 trunking 
system as well as a conventional repeater-based 
system. On a conventional system, radio users 
compete for access to individual channels, and one 
channel can be overloaded with traffic while others 
are often unused.

The trunking system allows several channels to be 
automatically shared by a number of radio users. 
These traffic channels are pooled and allocated, as 
required, for the duration of a call. As calls are 
completed, the traffic channels are returned to the 
pool, to be used for other calls. This system means 
reduced waiting times to make calls.

When you first switch to a talkgroup configured for 
P25 trunking, the radio attempts to access the 
network and register on a control channel.

If registration is successful, the trunking system 
available icon 

 appears in the display.

If registration is not successful, 

 does not appear, 

and the display shows No service.

The radio may sound five beeps, followed by a 
repeating double beep. The double beep continues 
until registration is successful.
