Viking Portable 600 Radio Operating Manual

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 button or menu parameter. Also select the scan 

list if applicable as described in the following “Selecting a Priority Scan List” 
description.

2 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.

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. 

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. “No List” (scanning disabled) or “Programmed” (default 
list) can also be selected if desired. The temporary programmed scan list is retained 
through radio power down.

The scan list is user selectable by the SCAN option switch. The scan list can also be 
temporarily changed if the Scan (List) Select option switch is programmed or by pressing/
holding the scan button. Refer to Section 5.10.1 for more information.To change the 
currently selected scan list (all channel types), proceed as follows:

1 With scanning disabled ( ) icon not displayed), press the Scan List option button or 

select the Scan Selct menu parameter.

2 The currently selected list is displayed as “List x”, where “x” is the currently selected 

list. To exit without changing the selected list, simply press the Scan List option button 
again or the <F1> button.
