control channel, radios may be programmed to automat-

ically scan the control channels of other systems. 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 programmed

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.
