Abstract
In response to a reception of a incoming signal by a receiver during operation of a turner circuit, a controller shifts a changeover switch and at the same time cause a ringing tone generator to output a ringing tone via a loudspeaker in a tuner section, thereby permitting the user listening to a broadcast to surely hear the ringing tone. In response to an operation to a control panel in a reception state of a telephone receiver, the controller causes the tuner circuit to operate and at the same time controlling a power supply switch to stop on-off switching, keeping the switch on to continuously supply electric power to the telephone section. Thus, power supply noise caused by the intermittent supply of power is prevented from affecting the tuner section, thereby checking a deterioration in the quality of broadcast voice.
