Abstract
A police radar warning receiver includes an auto-mute feature by which a driver may be alerted to the presence of police radar but without the annoyance of an unnecessarily prolonged audible alarm. To this end, upon detection of the police radar signal, an audible alarm begins to beep at a selected intensity and at a beep rate corresponding to the strength of the signal. A predetermined time and/or a predetermined number of beeps after detection of the police radar signal, the intensity of the audible alarm is automatically reduced.
