4.8 SCANNING
4.8.1 INTRODUCTION
Scanning monitors the channels in the scan list
for messages that 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 (unless it has been
disabled). 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 basic scan modes available:
Priority (Standard) and Radio Wide. The operation of
the priority type is unique to the type of channel
selected, and the operation of Radio Wide type is the
same regardless of the type of channel selected. Only
one type can be enabled at a time. For example, if
priority scanning is enabled and radio wide scanning is
selected, priority scanning is automatically disabled
and vice versa. More information on these types of
scanning follows.
4.8.2 PRIORITY SCANNING
Priority scanning (also referred to as standard
scan) 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.
More information on how priority scanning oper-
ates in the Conventional Mode is located in Section
5.11, and for the other modes in Section 6.12. Priority
scanning is turned on and off by the Scan option
switch or menu parameter as follows. If this switch or
menu parameter is not programmed, Priority scanning
is not available.
• Enable scanning using the Scan option switch or
menu parameter. Scanning is enabled when “Scan
On” is briefly displayed and the icon is
indicated.
• To turn scanning off, press the Scan option switch
again or select “Off” in the scan menu. Scanning is
disabled when “Scan Off” is briefly displayed and
the icon is no longer indicated.
• If the zone or channel is changed while scanning is
selected, scanning continues on the same or a
different scan list (see Section 4.9.1).
NOTE: Each SMARTNET/SmartZone and P25 trunked
channel can be programmed so that scanning is auto-
matically enabled when the channel is selected.
4.8.3 RADIO WIDE SCANNING
NOTE: Use radio wide scanning only if two different
channel types 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.
Radio wide scanning monitors the channels in the
preprogrammed radio-wide scan list. This scan list can
include up to 16 channels of any type and assigned to
any zone (see Section 4.9.2). Radio wide scanning is
turned on and off by the Radio Wide Scan option
switch or menu parameter as follows. If this switch or
menu parameter is not programmed, radio wide scan-
ning is not available.
• Enable Radio Wide Scanning using the Radio Wide
Scan option switch or menu parameter. Radio wide
scanning is enabled when “RW Scn On” is briefly
displayed and the icon is indicated.
• To turn radio wide scanning off, press the Radio
Wide Scan option switch again or select “Off” in the
menu. Scanning is disabled when “RW Scn Off” is
briefly displayed and the icon is no longer
indicated.
• If the zone or channel is changed while radio wide
scanning, scanning continues normally.
4.8.4 SCAN HOLD TIME
When a message is received or transmitted while
scanning, there is a delay before scanning resumes.
The delay after receiving a call prevents another
message from being received before a response can be
made. The delay after transmitting a call ensures that a
response is heard instead of another message occurring
on some other channel.
