6.13.2 Site Trunking
Site trunking occurs when a site can no longer participate in wide area trunking. It is
disconnected from other sides and only supports calls with other radios on that site and
cannot route audio to other sites. When site trunking is occurring, the radio searches for
other sites that may provide wide area coverage.

cannot route audio to other sites. When site trunking is occurring, the radio searches for
other sites that may provide wide area coverage.
Site trunking ends when a wide area coverage site is located, the current site is operating
again as a wide area coverage site, an out-of-range condition occurs, or the failsoft mode is
entered. The radio can be programmed so that “SITE TRUNKING” is displayed and/or an
alert tone sounds when site trunking occurs.

entered. The radio can be programmed so that “SITE TRUNKING” is displayed and/or an
alert tone sounds when site trunking occurs.
SmartZone and P25 trunked systems can be programmed for “Disable Site Trunking
Operation”. The radio is then not allowed to start or operate on a site trunking site. If a site
goes into site trunking, the radio leaves that site’s control channel and attempts to find
another valid wide area site. If no wide area site is available, the radio displays “OUT-OF-
RANGE”. If a site adjacent to the current Home Site was in site trunking but then enters
wide area trunking, it is evaluated to determine if it should move to that site as a better site.

6.13.3 Determining Current Site and Searching for a New Site
To display the RSSI level of the current site, press the SEARCH option switch. The
display then indicates the current site number as “SITE xx” and the RSSI (Receive Signal
Strength Indicator) signal level as “RSSI xx”. This mode is then automatically exited.

To scroll through the other programmed sites, press and hold the SEARCH option switch
while “SITE xx” or “RSSI xx” is displayed. If site lock is ON when site search is entered
(see following), the radio will be locked on the new site when this function is exited.

6.13.4 Locking / Unlocking a Site
It is sometimes desirable to stay on a site. To prevent the radio from searching for a new
site, lock it on the current site by pressing the LOCK option switch. The display then
momentarily indicates the site alias to indicate that the current site is locked (“x” is the
current site number). To unlock the site, press the LOCK option switch again and
“UNLOCK” is momentarily displayed.
