Roaming function
(P25 Trunking mode only)
The P25 Trunking mode allows the transceiver to move to an-
other system or WACN (Wide Area Communication Network),
according to the preset roaming list*, in order to find a site
that has a higher quality signal, or provides better services.
The Roaming function is automatically activated when the
transceiver goes out of the range and does not receive the
downlink signal from the repeater in the current registered
home system.
* The valid roaming areas (up to 10) are listed on the roaming list.
n
Site Lock function
(P25 Trunking mode only)
The transceiver can be locked into the current site with
[Site Lock].
When the Site Lock function is activated, roaming and the
background scan are inhibited.
This function is helpful when staying within one site and you
don’t want the transceiver to roam or scan other sites.
However if the transceiver goes out of the range and does
not receive the downlink signal from the current site, the
transceiver will automatically start hunting for a valid site,
even if the Site Lock function is activated.
✔
What is the Background Scan?
When this function is ON, the transceiver always monitors
a control channel of an adjacent site while operating in the
registered site. (Default: OFF)
