Viking Portable 600 Radio Operating Manual

4-9

The user can enter the scan list edit mode for the selected scan list while the radio is 
scanning without manually turning scan off. If the user presses the scan edit button while 
the radio is scanning, the radio shall stop scan and enter directly into scan list edit mode 
for the selected scan list. The scan edit mode shall timeout after seven seconds of 
inactivity. If the scan edit mode times out, or the user exits the mode via the exit button or 
the scan list edit function button, the radio shall save the changes to the scan list and restart 
scan.

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.

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 operates in the Conventional Mode is located 
in Section 5.10, "Conventional Mode Scanning", and for the other modes in Section 6.10, 
"SmartNet / SmartZone / P25 Trunked Scanning Features". Priority scanning is turned on 
and off by the Scan option button or menu parameter as follows. If this button or menu 
parameter is not programmed, Priority scanning is not available.

• Enable scanning using the Scan option button 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 button 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 4.11.5.1, "Group / Priority Scan Lists").

When the transmitter is keyed while scanning is enabled, the transmission may occur on 
various channels as follows.

Conventional Operation - Transmissions can be programmed to always occur on the 
priority, selected, or receive channel (if applicable). Refer to Section 5.10, 
"Conventional Mode Scanning" for more information.
