SCANNING TRUNKED SYSTEMS
The following features allow interaction with systems
other than the selected system to meet specific customer
needs. Wide Area System Scan and ProSound are
mutually exclusive options; however, Priority System
Scan will operate while ProSound is active.
Wide Area System Scan
The M-RK II radio may be programmed for wide area
system scan operation for multi-site applications. Upon
the loss of the currently selected system’s control chan-
nel, radios may be programmed to automatically scan the
control channels of other systems. If a new control chan-
nel is found, the radio will switch to the new system and
sound an alert tone.
ProSound
The radio may be programmed for ProSound system
scan operation for multi-site applications. ProSound
scanning is an enhanced replacement for wide area
system scanning. This algorithm insures that the radio
continually receives high quality audio. When the se-
lected system degrades to a pre-programmed level, the
radio changes to the new system and sounds a tone.
Should the control channel be lost completely, the radio
will scan the adjacent systems until a suitable one is
found.
