4.11 SCANNING
4.11.1 INTRODUCTION
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 (unless it has been
disabled).
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).
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 off-hook condition is not
detected, 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: Standard
(Priority) and Radio Wide. The operation of the stan-
dard type is unique to the type of channel selected, and
the operation of the Radio Wide type is the same
regardless of the channel type selected. Only one type
of scanning can be enabled at a time. For example, if
standard scanning is enabled and Radio Wide Scan is
enabled, standard scanning is automatically disabled
and vice versa. Refer to the following for more
information.

4.11.2 STANDARD SCANNING
Standard scanning (also referred to as priority
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 5.11, and for
more information on how it functions in the other
modes, refer to Section 6.12. Scanning is turned on
and off by the Scan option switch as follows. If this
switch is not programmed, scanning is not available.

To turn standard scanning on, press the SCAN
option switch. Scanning is enabled when a rotating
option switch. 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. On conventional channels, this may also
select another list, so several presses may be
required (see Section 5.11). Scanning is disabled
when “SCAN OFF” is briefly displayed and
again. On conventional channels, this may also
select another list, so several presses may be
required (see Section 5.11). Scanning is disabled
when “SCAN OFF” is briefly displayed and
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 4.12.1).

matically enabled when the channel is selected.

4.11.3 RADIO WIDE SCANNING
NOTE: Use radio wide scanning only if two types of
channels need to be scanned at the same time such as
conventional and SMARTNET/SmartZone. Otherwise,
use the more efficient standard 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
may contain up to 16 channels of any type assigned to
any zone (see Section 4.12.2). Radio wide scanning is
turned on and off by the RWS option switch as
follows. If this switch is not programmed, radio wide
scanning is not available.
