SMARTNET / SmartZone / P25 Trunked Features
7.13.3 Determining Current Site and Searching for a New Site
To display the RSSI level of the current site, press the SEARCH option switch. The
display then indicates the current site number as “SITE xx” and the RSSI (Receive Signal
Strength Indicator) signal level as “RSSI xx”. This mode is then automatically exited.
To scroll through the other programmed sites, press and hold the SEARCH option switch
while “SITE xx” or “RSSI xx” is displayed. If site lock is ON when site search is entered
(see following), the radio will be locked on the new site when this function is exited.
Note
If a site failure occurs, the radio will automatically leave the failed site and register on
another site (after a predetermined delay). When the failed site recovers, the radio will
(after a predetermined delay) return to the site.
7.13.4 Locking / Unlocking a Site
It is sometimes desirable to stay connected to a specific site. To prevent the radio from
searching for a new site, lock it on the current site by pressing the LOCK option switch. To
unlock the site, press the LOCK option switch again and “UNLOCK” is momentarily
displayed.
When the user site locks the radio, the icon will begin to flash. The site lock indicator
will be hidden while the radio is in menu mode, unit call, or interconnect call. Site lock is
a global setting but the icon will only be displayed in P25 and SmartZone.
7.13.5 Auto Site Search
Auto site search automatically searches sites and ranks them in a “Best Sites” list. Press
the Auto Site Search option switch to display the current site number or alias and RSSI
level of the current site. A "Press and Hold" of the Auto Site Search option switch will
cause the radio to automatically move from the current site and select the first/next site
from the "Best Sites" list.
7.13.6 ZoneFail Site Lock
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 zone 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 7.13.2 for more Site
Trunking information).
