The BC250D comes with an RF Attenuation feature. If you're
near an unusually strong signal source, the signal may
overload the scanner. The scanner may stop repeatedly on
that signal and miss other transmissions.

The RF Attenuation feature works in all modes and attenuates
(reduces) the incoming signal strength to prevent stronger
signals from overloading the scanner.

The RF attenuation is set at the menu mode.
