  • Aural annunciator circuit for a receiver
    Patent number: 5404582
    Abstract: An aural annunciator circuit for a radio receiver and a radio transceiver incorporating such. The annunciator circuit is operative to generate an aural signal when a signal is transmitted to the receiver in a manner analogous to telephonic ringer circuitry of conventional telephonic apparatus. The aural signal is of a signal level of a relatively high magnitude when the receiver in which the aural annunciator circuit is embodied is configured in a closed configuration and the aural signal is of a relatively low magnitude when the receiver is configured in an open configuration.
