Trunking Operation
Site Trunking
In a SmartZone system, if the zone controller for a particular site fails,
the site enters into a site-trunking operational mode. In this mode of
operation, the user can only communicate with other units at the
same site.
Radios in a SmartZone system can be programmed by a qualified
radio technician to display
STE TRNK (W7) or STE TRUNK (W9) when
site trunking becomes active. The display alternates with the current
mode display as long as the radio remains in site trunking. The radio
also sounds a valid-key chirp when it first detects site trunking.
Out-of-Range Indication
The out-of-range display/audible indication feature can be enabled by
a qualified radio technician.
OUT OF RANGE and the current selected
mode are alternately displayed, and a low-pitched tone sounds every
six seconds:
• When the radio is out of range of the system and can no longer
lock onto the control channel
OR
• When the radio is in failsoft and cannot lock onto the failsoft
channel.
The out-of-range indication remains in effect until one of the following
conditions occur:
• The radio locks on a control channel
• The radio locks on a failsoft channel
• The radio is turned off
