Abstract

PURPOSE:To enable to receive the information surely without causing various hindrances, by providing the memory means to tentatively store the audio signal at least at the slave unit and the means reproducing this signal at required time. CONSTITUTION:The slave unit is provided with the memory unit 27, switch 28 to reproduce the signal, and control circuit 23. The radio frequency signal received 21 at the slave unit is demodulated 22, timing is taken by detecting the cynchronizing signal at the circuit 23, and when the selection call-out signal specific to the slave unit is detected 24, the oscillator 25 is controlled 23 to produce the call-out tone from the speaker 26 and control 23 is made the audio signal inputted succeedingly is written in the unit 27. Next, when the called party hears the call-out tone 26 and depresses the switch 28, the operation of the oscillator 25 is stopped via the circuit 23 and call-out tone is stopped. When the called party depresses the switch 28 again at an appropriate time, digital audio signal is read out from the unit 27 with the control of the circuit 23, and it is converted 29 into analog audio signal and reproduces from the speaker 26.
