Trunking System Controls
This chapters explains the trunking system control features in your radio.
2.9.1
Operating in Failsoft System
When and where to use:
The failsoft system ensures continuous radio communication 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, your radio transmits and receives in conventional operation on a
predetermined frequency. You hear a medium-pitched tone and the display shows Failsoft.
When the trunking system returns to normal operation, your radio automatically leaves failsoft
operation and returns to trunked operation.
To continue in Failsoft and to communicate with other talkgroups, refer to the following procedure.
Procedure:
1 Rotate the 16–Position Select Knob to change to a different repeater frequency.
2 Press the PTT button to talk, and release the button to listen.

Out-of-Range Radio
When your radio goes out of the range of the system, it can no longer lock onto a control channel.
You hear a low-pitched tone and/or the display shows the currently selected zone/channel combination
and Out of range. Your radio remains in this out-of-range condition until it locks onto a control
channel or failsoft channel, or if it is turned off.
2.9.3
Site Trunking Feature
If the zone controller loses communication with any site, that site reverts to site trunking. When this
occurs, you can communicate only with the radios within your trunking site.
The display shows the currently selected zone/channel combination and Site trunking.
