Abstract: An electronic apparatus is provided that comprises a shock detector for detecting a shock received by an electronic apparatus such as a portable telephone, a controller for comparing the value of the shock as detected by the shock detector with a reference value, and a memory element for storing an identifying signal generated when the value of a shock has exceeded the reference value and the value of shock. This enabling easy determination as to whether or not a breakdown has been caused by shock.
