using the attenuator

To reduce interference or noise caused by strong
signals, you can reduce the scanner's sensitivity to
these signals.
There are two attenuator modes in your scanner.
One is normal attenuator mode in which you set the
attenuator in each channel or each band/group in the
search and tune mode. The other is global mode in
which you set the attenuator only once. This setting is
applied all the time in every mode.
