to
decide under what
condition
you
want your dual bander to continue
scanning
after detecting and stopping for a signaL
You
can choose Time-operated Scan or Carrier-operated

Your dual bander stops scanning after detecting a
signal, remains there for approximately 5 seconds,
and
then continues
to
scan even if the signal
is
still
present.
•
Carrier-Operated
Scan
Your dual bander stops scanning after detecting a
signal
and remains
on
the same frequency until the
signal drops out. There is a 2 second delay between
signal drop-out and scan resumption
to
allow time
for any responding stations
to
begin transmitting.
