First Claim
1. Apparatus including a receiver circuit, a microprocessor, an input/output (I/O) port, at least one switch for configuring the I/O port, the at least one switch coupled to the microprocessor, an audio amplifier coupled to the receiver circuit and to the I/O port, an audio frequency transducer coupled to the I/O port, and a power supply coupled to the I/O port, the receiver, the microprocessor, the at least one switch, and the audio amplifier, the audio frequency transducer being selectively coupled to the audio amplifier through the I/O port, and the power supply being selectively coupled to the I/O port, to permit activation of the audio frequency transducer by a signal coupled from the audio amplifier through the I/O port and access to the power supply through the I/O port.

Abstract
A radio includes a receiver circuit, a microprocessor, an input/output (I/O) port, at least one switch for configuring the I/O port, an audio amplifier coupled to the receiver circuit and to the I/O port, an audio frequency transducer coupled to the I/O port, and a power supply coupled to the I/O port, the receiver, the microprocessor, the at least one switch, and the audio amplifier. The at least one switch is coupled to the microprocessor. The audio frequency transducer is selectively coupled to the audio amplifier through the I/O port and the power supply is selectively coupled to the I/O port to permit activation of the audio frequency transducer by a signal coupled from the audio amplifier through the I/O port and to provide access to the power supply through the I/O port.
