Abstract

PURPOSE:To prevent a receiver from continuing to sound in case when an input wave is unstable, by constituting so that a continued code is returned automatically to a holding state, unless the continued code which is generated periodically after a low-frequency amplifier has been operated by a start code is received and discriminated. CONSTITUTION:An emergency broadcast consisting of a start code, an emergency information signal, a continued code, an emergency information signal and an end code is sent from a sending antenna 1. A receiving side receives it by an antenna 8, and also demodulates a control code and an emergency information by a receiving part 9. The start code, the continued code and the end code are discriminated by a control code discriminator 12. A monostable multivibrator 16 is set by a start code discrimination output 13, and this output drives a switch 17, makes a low-frequency amplifier 10 to an operating state, and an emergency information is heard from a speaker 11. Unless a continued code discrimination output 14 is obtained within a prescribed period by some reason, a circuit 16 is reset.
