Radio Wide Features
5.12 Scanning
Scanning monitors the channels in the scan list for messages the radio is programmed to
receive. When a message is detected, scanning stops and the message is received. Shortly
after the message is complete, scanning resumes.
If the microphone off-hook condition is detected (Hangup Box Monitor selected by
programming), scanning stops and selective squelch (such as Call Guard CTCSS or NAC/
group ID detect) is disabled on conventional channels. If the microphone off-hook
condition is not detected (Hangup Box Monitor is not programmed), taking the
microphone off-hook has no affect on radio operation. When a call is received in the scan
mode, the alias of the channel on which a call is received (and any other display
parameters that may be programmed) are displayed until scanning resumes. The selected
channel alias is then displayed if applicable.
There are two scan modes available: Priority (standard) and Radio Wide. The operation of
the priority type is unique to the system type programmed on the selected channel, and the
operation of the Radio Wide type is the same regardless of the system type programmed
on the selected channel. Only one type of scanning can be enabled at a time. For example,
if priority scanning is enabled and Radio Wide Scan is enabled, priority scanning is
automatically disabled and vice versa. Refer to the following for more information.
5.12.1 Priority (Standard) Scanning
Priority scanning (also referred to as standard scanning) monitors only channels that are
the same type as that currently selected. For example, if a conventional channel is selected,
only conventional channels are scanned and likewise for SMARTNET/SmartZone and
Project 25 trunked channels.
For more information on scanning functions in the Conventional mode, refer to Section
6.10, and for more information on how it functions in the other modes, refer to Section
7.11. Scanning is turned ON and OFF by menu selection or (if programmed) by the Scan
option switch as follows.
• To turn priority scanning on, press the SCAN option switch (or select via menu).
Scanning is enabled when a rotating is indicated in the right status display as follows
and “SCAN ON” is briefly displayed.
• To turn scanning OFF, press the SCAN option switch again. Scanning is disabled when
“SCAN OFF” is briefly displayed and is no longer indicated in the status display.
