ABSTRACT:
A radio receiver, optionally used in conjunction with a handheld audio system, includes a radio stage for processing a received radio signal into an audio signal. An audio stage produces an audio output, based on the audio signal. An overload monitor detects an overload condition in the radio stage and generates an overload signal in response to the detected overload condition. A controller controls the audio output in response to the overload signal.
