Group / Priority Scan Lists
A scan list is 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 255). 
The only limitation is the available memory. Each scan list can include up to 255 
channels/talkgroups. More information on selecting and editing priority scan lists follows.
Note
The selected channel is always scanned.
4.11.5.1.1
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).
Enable priority scanning using the Scan button or menu parameter. Also select the scan 
list if applicable as described in the following “Selecting a Priority Scan List” 
description.
Select the desired zone and then scroll through the channels by rotating the channel 
switch. When the displayed channel is in the scan list (scanned normally), the   icon 
is displayed.
4.11.5.1.2
Selecting a Priority Scan List
Note
Only priority scan lists are selectable.
Conventional systems can be programmed with a scan list that is normally selected by all 
channels in that system. However, there is a programmable option to slave a particular 
conventional scan list to a zone. This then becomes the default list for all conventional 
channels in that zone (it overrides the system programming).
The default scan list (which is to be used by all conventional channels except those 
belonging to slaved zones), can be temporarily changed by using the Scan List Select 
option button or the menu parameter. A scan list selected in this manner is retained 
through radio power down. 
Conventional, SmartNet/SmartZone and Project 25 Trunked Channels - Each channel 
(talkgroup) can be programmed so that one of the programmed lists is selected or scanning 
is disabled (No List). In addition, channels can be programmed so that scanning is 
automatically enabled (Auto Scan) when they are selected. 
If the Scan (List) Select option button or menu parameter is programmed, the list that is 
selected by all talk and announcement groups in the current system can be temporarily 
changed by the user as follows. “None” (scanning disabled) or “Programmed” (default 
list) can also be selected if desired. The temporary programmed scan list is retained 
through radio power down.
