Using the Failsoft System
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.
The failsoft condition is indicated by a faint beeping tone every
nine seconds (radio unsquelched) until the trunking system
returns to normal operation.
To continue, in Failsoft, to communicate with other talkgroups,
refer to the following procedure.
Procedure:
1
Rotate the Mode Knob to change to a different repeater
frequency.
2
Press the PTT button to talk, and release the button to
listen.
When the trunking system returns to normal operation, your
radio automatically leaves failsoft operation and returns to
trunked operation.
Going Out-of-Range
OUT OF RANGE when your radio goes out of the range of the
system, it can no longer lock onto a control channel.
Procedure:
1
A low-pitched tone sounds.
AND/OR
The display shows the currently selected zone/channel
combination and OUT OF RANGE.
2
Your radio remains in this out-of-range condition until:
It locks onto a control channel.
OR
It locks onto a failsoft channel.
OR
It is turned off.
Using Site Trunking Feature
If the zone controller loses communication with any site, that
site reverts to site trunking.
The display shows the currently selected zone/channel
combination and SITE TRUNKING.
Note:
When this occurs, you can communicate only with
other radios within your trunking site.
