Next, the control unit 10 receives the instruction signal from the master station (S14) and determines whether or not it is necessary to monitor the already registered broadcast contents (S15). If a monitor is required, the registered contents are read out and the contents are confirmed by the master station just in case (S16). As a result of this confirmation, an instruction signal operated and input by the operator is received (S17), and it is determined whether or not the broadcast execution instruction has the registered content (S18). As a result of the determination, if the instruction is a broadcast execution instruction, the contents stored and registered in the registration memory 9 are broadcast through the external speaker 4 (S19). If the monitor is unnecessary in S15, the process immediately proceeds to the process in S18, and if the execution instruction is not confirmed in S18, the process ends.
