Chapter 6
Trunking System Controls
This chapter explains the trunking system control features on your radio.
6.1
Operating in Failsoft System
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. To continue in Failsoft and to communicate with other talkgroups, refer to the following
procedure.
Procedure:
1 Rotate the Channel Selector knob to change to a different repeater frequency.
2 To call, press and hold the PTT button.
3 To listen, release the PTT button.
6.2
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.
6.3
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 and the Site Trunking message.
6.4
Locking or Unlocking Sites
This feature allows your radio to lock onto a specific site and not roam among wide-area talkgroup
sites. This feature must be used with caution because it inhibits roaming to another site in a wide-area
system.
Procedure:
1 Press the Site menu item.
2 Perform one of the following actions:
• To lock the site, press Lock.
• To unlock the site, press Unlk.
The display shows a notification to indicate if the site is locked or unlocked. The radio saves the new
site lock state and returns to the Home screen.
