automatically scan the control channels of other sys-
tems. If a new control channel is found, the radio will
switch to the new system and sound an alert tone.
Priority System Scan
The radio may also be programmed for priority sys-
tem scan. A priority system may be assigned among the
systems programmed into the radio. Radios pro-
grammed in this manner will check for the priority trunked
system’s control channel at a programmable rate ranging
from 1 to 16 minutes. This priority scan timer is reset each
time the PTT button is pressed or when a call is received.
If the priority system control channel is found, the radio
will automatically switch to the priority system.
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.
