instructed above, then set the Scanning Switch to the AUTO position.
The PRO-2001 will constantly scan each channel in sequence; when a
signal appears on one of the channels, the Receiver will lock onto that

For Manual scanning, the Receiver can be either "squelched" or
"unsquelched"; for Automatic scanning, SOUELCH must be set to
eliminate the background noise.

monitoring for two seconds after a message has ended; if no further
message is received by then, scanning is resumed. DELAY functions
