US 6,212,410 B1 · Portable telephone apparatus with security function

Abstract

A portable telephone apparatus with a security function includes a first detecting and processing circuit for determining whether or not identification information of a portable telephone main unit and identification information of a battery unit that supplies power to the portable telephone main unit match, and for supplying the power to the portable telephone main unit when the identification information of the portable telephone main unit and the identification information of the battery unit match. The portable telephone apparatus also includes a second detecting and processing circuit for determining whether or not identification information of the battery unit for use with the portable telephone main unit and identification information of a battery charger that charges the battery unit match, and for causing the battery charger to supply power to the battery unit when the identification information of the battery unit and the identification information of the battery charger match. When identification information of the portable telephone main unit, the battery unit, and the battery charger match, the power to the portable telephone main unit is turned on and thereby the battery unit is charged.
