Abstract
A circuit and method for a portable telephone prevents a finder from exploiting the interests of the owner if the telephone becomes lost. The method contemplates the steps of: generating an audible alarm and a first message requesting input of a predetermined password when one of a predetermined time period elapses and a number of outgoing calls exceeds a predetermined number after an alarm function is enabled; detecting whether the predetermined password is input, and stopping generation of the alarm and the first message when the predetermined password is input; generating a second message indicating how an owner of the portable telephone can be contacted and activating a loss mode of the portable telephone when the predetermined password is not input; and automatically dialing a telephone number corresponding to the owner when a predetermined key on the portable telephone is input after the loss mode is activated.
