Trunking Operation
SmartZone® (W7 and W9 Control Heads Only)
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 W7 and W9 Control Heads: the Site and Lock
buttons. These buttons can be used to check, or change, the
SmartZone operation.
