Trunking System Controls
This chapters explain the trunking system control features in your radio.
34.1
Operating in Failsoft System
The failsoft system ensures continuous radio communication during a trunked system failure. When the
radio goes into failsoft operation, it automatically switches to a failsoft channel which allows your radio
to transmit and receive in conventional operation on a predetermined frequency.
When in failsoft operation, the radio emits 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.
Procedure:
If you want to communicate with other talkgroups during failsoft operation, rotate the Channel
Selector to a different repeater frequency and press PTT to talk.
34.2
Imbalanced Coverage
Imbalanced coverage occurs when the radio is able to receive the control channel but is unable to
transmit back to the system. The radio generates a periodic tone and displays No Comms.
34.3
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 notification. 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.
34.4
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 and the Site Trunking message.
