Abstract: A portable terminal device comprises an antenna for receiving radio waves from a base station, an incoming call alarm for notifying the user of the reception of radio waves, a control circuit provided between the antenna and the alarm for activating the alarm and a memory. The memory is capable of storing therein a predetermined incoming call rejecting condition or incoming call notifying condition via the control circuit. The control circuit includes comparison means for detecting whether one of information as to the current time and date, information as to the self-location of the device and information as to the caller or the combination of these items of information is in match with the incoming call rejecting condition or incoming call notifying condition stored in the memory. The control circuit has the function of changing over to predetermined incoming call rejecting means or incoming call notifying means when a match is obtained.
