ABSTRACT:
When a portable terminal apparatus such as a radiotelephone malfumctions, such status can be detected, and it is diagnosed whether the portable terminal apparatus is out of order. Thus, the portable terminal apparatus can be maintained efficiently. The portable terminal apparatus includes a reception state detecting unit for analyzing a reception state of a receiving unit, and a display unit for displaying a message on the basis of an analyzed state at the reception state detecting unit, thereby when a failure of connection or maintenance of the communication network is detected, a predetermined message is displayed on the display unit. Further, the portable terminal apparatus includes a memory for storing log data concerning communication with a base station when the control circuitry detects a failure of communication.
