送信機１はオフとなる。 If either transmitter 1 or receiver 2 is malfunctioning or the channels used are different, no received sound will be produced. It can also detect intermittent 1KHz tones that are interfering with other stations, as well as line conditions. If an audio signal is input to the audio signal input terminal 3 before the 5-second timer circuit 13 times up, it is detected by the detection circuit 4, and the detected signal turns on the oscillation/modulation circuit 5 via the OR circuit 7.
And the intermittent sound generation circuit 9 is turned off. Therefore, the carrier wave for channel 1 based on the audio signal input to the modulation input terminal 6 is modulated and transmitted. That is, regardless of the operation of the timer circuit 13, the audio signal is emitted from the antenna 20 in the form of radio waves, giving priority to the 1 KHz intermittent tone. When the audio signal disappears,
Transmitter 1 is turned off.
