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 or channel, and the site trunking message.

Site Search
When searching for a site, your radio is inoperable. In the site search mode, your radio scans for

Other trunking states are such as Out of Range and Imbalanced Coverage.
The Searching site indicator alerts you that your radio is attempting to search for a valid trunked
control channel.
