Viking™ VP600 Portable Radio Operating Manual

When using this radio with SmartNet or SmartZone trunking system(s), a different connect 
tone during failsoft operation can be programmed. The failsoft connect tone setting will 
normally be selected to “Default.” This means that the connect tone used during failsoft 
will be the connect tone setting the system sends over the air, or the programmed connect 
tone if no over the air value is received. If it is known, the connect tone during failsoft 
operation can be programmed. If a value other than “Default” is programmed, the radio 
will always use this connect tone setting during failsoft operation.

Scanning on a SmartNet/SmartZone and P25 Trunked systems is called Priority Monitor 
Scan. The following are unique features of this type of scanning. For general scanning 
information applicable to all operating modes, refer to Sections 4.11 and 4.11.5.

• Scanning is turned on and off by the Scan option button or menu parameter. Talkgroups 

(channels) can be programmed so that scanning automatically starts when the talkgroup 
is selected (Autoscan).

• When responding to calls in the scan mode, the programming of the Talkback Type 

parameter determines if a response always occurs on the talkgroup of the call (Active 
Group) or the Selected Group if they are different. Transmissions at other times always 
occur on the selected talkgroup.

• Each talkgroup can be programmed to select one of the programmed scan lists or “No 

List” (scanning is disabled). If scanning is enabled and the selected channel does not 
permit scanning, it is automatically enabled again when a channel is selected that 
permits scanning.

• Up to 255 scan lists, each with up to 255 talkgroups from the same system can be 

programmed. The selected scan list can be temporarily changed and edited as described 
in Section 4.11.5.1, Group / Priority Scan Lists.

• In addition to calls on channels in the scan list, pages, unit calls, and telephone calls are 

received while scanning. Unit and telephone calls are not interrupted by priority 
messages.

Every radio on the system has to register with the Zone or Site Controller so that the 
system knows where everyone is and if traffic from one site needs to be sent to another 
site. This is determined by the list of talkgroups associated with the radio.
