Abstract

PURPOSE:To manage communication lines at a base radio station in case of failures, by providing a means controlling a transmitter function into operation or non-operation with a terminal radio station communicating with the base radio station, when a control signal is received. CONSTITUTION:In a terminal radio station, when a control signal is received on an antenna 49, a synchronizing signal detection circuit 60, data demodulation circuit 61, and code interpreting circuit 62 are operated, a switch circuit 57 is controlled to prevent the control signal tone from entering a speaker 59. When a station number information designated with the base radio set is outputted at a station number detection circuit 63 and it coincides with the number of station itself, a status control designation code designated with the base radio station is applied to a status control code detection circuit 64 for code detection and the result is outputted to a status memory 65. The content of the memory 65 is displayed on a display device 66, the information from the base station is a transmission stop signal, then a press- talk switch 47 is set to the transmission stop state. In case of emergency, even when it is in the state of the signal stop, the state can be transmitted to the base station as a control signal from the status set key 50.
