ABSTRACT:
A portable telephone apparatus including a battery alarm function wherein consumption of a battery apparatus through use of an additional function other than a talking function can be prevented to assure a lowest operation voltage for the talking function. The portable telephone apparatus includes a rechargeable battery, and a battery supervision section. The battery supervision section includes a voltage detection section for supervising and detecting a voltage of the battery controlled by a control section, and an alarming section for issuing a lowest operation voltage level alarm under the control of the control section when the detected voltage drops to a lowest operation voltage level that a talking function of the portable telephone apparatus can operate. The alarming section issues a supervision voltage level alarm when the detected voltage of the battery drops to a supervision voltage level different from the lowest operation voltage level.
