Automatic Multiple Site Selection (AMSS)

The automatic multiple site selection (AMSS) feature extends communications beyond the reach of a single trunked site (antenna location). In a system where wide-area coverage is required, multiple trunking sites are used.

AMSS automatically switches the radio to a different site when the current-site signal becomes too weak. Typically, this happens when the radio is moved out of the range of one site and into the range of another. Under normal conditions, this switching is invisible to the user.

Viewing the Current Site and Forcing a Site Change

1.Momentarily press the search button (programmed via the RSS).

a.If the radio is presently locked onto a site, the display will show the number of current site.

b.If the radio is scanning for a new site, the display will show “SCANNING” until it locks onto a new site, then it will show the number of the new site.

2.Press and hold down the search button to manually force the change to a new site. You will hear a tone and the display will show “SCANNING” while the radio scans for a new site.

Then, the radio will automatically return to the home display.
