ABSTRACT:
A portable cordless telephone transceiver-radio receiver includes a headset which is driven by the audio output of a radio receiver until an incoming radio frequency (RF) telephone ring signal is detected by a telephone receiver. A telephone audio ring signal is generated based on the detected RF ring signal and the audio ring signal is converted to sound at the headset. The audio ring signal operates a latch which blocks or squelches the audio output of the radio receiver from the headset until the latch is reset. A "talk/off" switch is operated by the user to initiate and terminate conversation and to automatically reset the latch. In another embodiment, the radio receiver is squelched or turned off directly by the "talk/off" switch. In a further embodiment, the audio ring signal is blocked from the head set until a prescribed number of audio ring signals have been detected.
