ABSTRACT:
In a mobile telephone device (10) comprising a serial interface (13b) and subjectable to an aging operation with an aging device (20) connected to the serial interface, a central processing unit (12) delivers a clock signal to an aging jig (25) through an interface unit (13) and the serial interface. In synchronism with the clock signal, the aging jig supplies particular data to the central processing unit through the interface unit and the serial interface. The central processing unit receives serial data supplied to the serial interface as received data in synchronism with the clock signal. The serial data is supplied to the serial interface both during progress of the aging operation and while the mobile telephone device is not subjected to the aging operation. The central processing unit judges whether or not the received data coincides with the particular data. When the received data coincides with the particular data, the central processing unit carries out the aging operation.
