Special Radio Features
• Failsoft
If a trunking system experiences a complete failure, 
the radio will revert to failsoft operation and 
automatically switch to its failsoft channel. During 
failsoft, the trunking repeaters will transmit a 
medium-pitched tone every 10 seconds. When the 
trunking system returns to normal operation, your 
radio will automatically leave the failsoft operation 
and return to trunked operation.
• Out-of-Range
If you go out of range of the system and can no 
longer lock onto a control channel, the display will 
alternately display “

” and the 
currently selected zone/channel combination, and/
or sound a low-pitched tone. Your radio will remain 
in this out-of-range condition until it (1) locks onto 
a control channel, (2) locks onto a failsoft channel, 
or (3) the radio is turned off.
• Site Lock
This feature allows your radio to lock onto a specific site and not roam among 
wide-area talkgroup sites. This is particularly useful when operating at the 
fringe of a system’s coverage.
