Then, by depressing the press key of a hand microphone 18, communication with the master station is enabled. Namely, the number of the master station as the command station is displayed on the display 8 by turning on the power supply key 15 and switched by the master/Gr/simultaneous key. When the press key is pushed in this displayed station state, transmission to that displayed station is enabled. For the operation, the operation at the command station is similar as well. Because of this operation, the transmission is enabled, while selecting the master station to perform transmission extremely easily, in comparison with the conventional case of inputting the personal number.
