RADIO-WIDE FEATURES

Separate delay times are programmable for Radio
Wide and Priority scanning. With radio wide and
conventional priority scanning, delays of 0-7.5
seconds are programmable in 0.5-second steps. With
SMARTNET/SmartZone and P25 Trunked priority
scanning, a scan delay of 2-10 seconds can be
programmed in 0.5-second steps.

4.8.5 TRANSMITTING IN THE SCAN MODE
Priority Scan Mode
When the transmitter is keyed while scanning is
enabled, the transmission may occur on various
channels as follows.
channels as follows.
Conventional Operation - Transmissions can be
programmed to always occur on the priority,
selected, or receive channel (if applicable). Refer to
Section 5.11 for more information.

Operation - If scanning is halted to receive a
message, programming determines if transmis-
sions occur on the selected or active channel.
Transmissions at other times occur on the selected
channel.

The radio can be programmed to transmit on the
selected or active channel similar to SMARTNET/
SmartZone and P25 trunked operation just described.

4.8.6 NUISANCE CHANNEL ADD/DELETE
With priority scanning, channels can be tempo-
rarily deleted from the scan list, for example, if
messages become annoying. This feature is not avail-
able with radio wide scanning. Channels can also be
permanently added or deleted from a scan list as
described in the next sections. Proceed as follows to
temporarily delete a nuisance channel:
messages become annoying. This feature is not avail-
able with radio wide scanning. Channels can also be
permanently added or deleted from a scan list as
described in the next sections. Proceed as follows to
temporarily delete a nuisance channel:
NOTE: The selected channel and also priority chan-
nels cannot be deleted from the scan list.

1. While receiving a message on the channel to be
deleted, press and hold the Scan option switch until
a tone sounds (about 1 second).
a tone sounds (about 1 second).
2. The channel is then deleted and scanning of the
remaining channels in the scan list resumes.
3. Deleted channels are added back into the scan list if
any of the following occur:
•
Scanning is turned off and then on again using the
Scan option switch or menu parameter.

•
Radio power is turned off and then on again.
•
The selected channel is changed.
4.9 SCAN LISTS
4.9.1 PRIORITY SCAN LISTS
General
NOTE: The selected channel is always scanned.
A scan list is simply the channels that are scanned
when scanning is enabled. With all operating modes,
as many priority scan lists as are required can usually
be programmed (up to 256). The only limitation is the
available memory. Each scan list can include up to 512
channels/talk groups. More information on selecting
and editing priority scan lists follows.

Determining Channels in Priority Scan List
The channels in conventional priority scan lists
are indicated by selecting the scan mode as follows.
Channels in SMARTNET/SmartZone/P25 Trunked
priority scan lists are indicated only when editing a
scan list (see “Editing a Priority Scan List” which
follows).

1. Enable priority scanning using the Scan switch or
menu parameter. Also select the scan list if appli-
