Going Out-of-Range

Procedure:

AND/OR
The display shows the currently selected zone/channel

It locks onto a control channel.

SmartZone

®
The SmartZone
feature extends communications beyond the
reach of a single-trunked site (antenna location) when operating
in a SmartZone system. SmartZone units provide expanded
wide-area coverage.
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.
Under normal conditions, a SmartZone-enabled radio functions
invisibly to the operator. However, the operator does have some
manual controls on the Control Head – the RSSI menu entry.
This button can be used to check, or change, the SmartZone
operation.


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.
