Radio Wide Features
4.12.1 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 trunking channels.
For more information on scanning functions in the Conventional mode, refer to Section
5.10, and for more information on how it functions in the other modes, refer to Section
6.11. 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 (Standard
Control Head) or is displayed in the top middle of the display (Lightning Control
Head)
• To turn scanning OFF, press the SCAN option switch again. Scanning is disabled when
“SCAN OFF” is briefly displayed and (Standard Control Head) or (Lightning
Control Head) is no longer indicated in the status display.
• If the zone or channel is changed while scanning is selected, scanning continues on the
same or a different scan list (see Section 4.13.1).
Note
Each Conventional, SMARTNET/SmartZone and P25 trunked channel can be
programmed so that scanning is automatically enabled when the channel is selected.
4.12.2 Radio Wide Scanning
Radio wide scanning monitors the channels in the preprogrammed radio wide scan list.
This scan list may contain up to 16 channels of any type assigned to any zone (see Section
4.13.2). Radio wide scanning is turned ON and OFF by menu selection or by the RWS
option switch (if programmed) as follows:
Note
Use radio wide scanning only if two different types of channels need to be scanned at the
same time such as conventional and SMARTNET/SmartZone. Otherwise, use the more
efficient priority scanning because there is less chance of missed calls.
• To turn radio wide scanning on, press the RWS option switch and “RW SCAN ON”
(Standard Control Head) or “RW Scan On” (Lightning Control Head) is briefly
