Description
Site Roaming is the function to migrate automatically to the site (channel) providing better radio environment if
the transceiver is operated in an NXDN Conventional system.
The transceiver receives a synchronization signal transmitted from the repeaters in multiple sites at regular time
intervals, and detects the RSSI level. Therefore, the transceiver migrates automatically to the channel providing
better radio environment.
This function can be used by configuring
Site Roaming (NXDN) or Site Roaming with RAN (NXDN) channels for
each zone by using KPG-D6/ D6N.
Revert Channel
is the Zone-channel which is used when the transceiver transmits by pressing the
PTT
switch
during the scan.
The Revert Channel is displayed according to the configuration of
Revert Channel Display
.
