using attenuator
To reduce interference or noise caused by strong signals,
you can reduce the scanner’s sensitivity with the attenuator.
There are two attenuator modes in your scanner. Normal
attenuator mode allows you to set the attenuator on a
per-channel basis. Normal mode is useful when individual
channels are found to be prone to interference. Global
attenuator mode applies attenuation to every channel in the
scanner, and overrides any normal mode attenuator settings
that you may have entered.
To assign attenuation to a channel in the scanner,
press
ATT

navigate to a channel.

bank, or search group within a search bank. Press
