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

Out of range. Your radio remains in this out-of-
range condition until it locks onto a control channel, it
locks onto a failsoft channel, or it is turned off.

SmartZone units provide expanded wide-area

SmartZone automatically switches the radio to a
different site when the current site signal becomes
unacceptable. This usually happens when the vehicle
in which the radio is located is driven out of the range
of one site, and into the range of another.

Site Trunking Feature

Note:
When this occurs, you can communicate only

system.
You can toggle the lock state between locked and
unlocked by pressing the preprogrammed Site Lock/
Unlock button.
Follow the following procedure to lock and unlock a
site via the radio menu.
