受信装置。 A receiving device capable of receiving an FM stereo signal and a television audio multiplex signal includes a detection means that generates a predetermined voltage when receiving the television audio multiplex signal, and a main channel signal when receiving two audio signals of the television audio multiplex signal. Alternatively, a manual selection switch for selecting a sub-channel signal is provided, and by using a predetermined voltage obtained from the detection means as an operating voltage of the manual selection switch, the manual selection switch is activated at least when receiving the FM stereo signal. A receiving device characterized in that it is made inoperable.
