Viking Portable 600 Radio Operating Manual

6-19

It is sometimes desirable to stay on a site. To prevent the radio from searching for a new 
site, lock it on the current site by pressing the Site Lock option button or selecting that 
menu parameter. The display shows the flashing 

 icon to indicate that the site is locked. 

To unlock the site, press the Site Lock button again, (or the <F2> Select button), until 
“Unlock” is momentarily displayed.

Auto site search automatically searches sites and ranks them in a “Best Sites” list. The list 
is made up of all sites in the site list that share the highest site rank or have a site rank of 
less than the highest site rank. Sites are sorted by RFSS ID/Zone and then by Site ID.

Auto Site search is selected by the Auto Site Search option button or by menu selection.

1 Press the Auto Site Search option button (or select the menu parameter) to display the 

current site number and RSSI level of the current site.

2 Press and hold the Auto Site Search option button (or use the menu) to move from the 

current site and scroll through the “Best Sites” list.

If menu selection is used, two items can be displayed:

- “Site Disp” displays the current site number or alias and RSSI indicator.

- “Auto Site” moves from the current site to the next (or first) site in the Best Sites list.

This is an optional feature that can be enabled only by factory programmed. It does not 
require any special inputs from the infrastructure to operate. This feature is intended to 
prevent some of the confusion resulting from a site controller failure. When this occurs, all 
sites go into the Site Trunking mode and radios will be unable to roam normally. The 
result is that the various radios selected by a particular talkgroup may be operating on 
different sites and are unable to talk to each other (see Section 6.12.3, Site Trunking for 
more Site Trunking information).
