SOLUTION: A receiving circuit 22 for announcing an incoming call of an incoming call announcing device 2 measures and demodulates the magnetic field intensity of a received radio wave. A control circuit 23 for announcing an incoming call judges transmitted information transmitted from a portable telephone device 1, operates a vibrator 25 and an LED display 26, and monitors the state of a push button switch 27. Also, a storage circuit 24 for announcing an incoming call stores identification information for individually identifying the incoming call announcing device 2 and the in-zone information or out-zone information of the portable telephone device 1. Then, not only the control information but also the other information is made different between the case of oscillating the incoming call announcing device and the case of turning on an LED or the like without oscillating the incoming call announcing device, that is, between the case of oscillating it as an announcing means and the case of not oscillating it as an announcing means. |
