Failsoft
The failsoft system ensures continuous radio communications during 
a trunked system failure. If a trunking system fails completely, the 
radio goes into failsoft operation and automatically switches to its 
failsoft channel. 
During failsoft operation:
When the trunking system returns to normal operation, your radio 
automatically leaves failsoft operation and returns to trunked 
operation.

If you go out of the range of the system, and can no longer lock onto a 
control channel: 
Your radio transmits and 
receives in conventional 
operation on a 
predetermined frequency. 
You hear a medium-pitched 
tone every 10 seconds.
