Abstract

A unique cellular portable telephone (100) automatically accommodates a power source change during a cellular telephone call between the portable's battery (300) and another battery (300) or an external power source from vehicular adaptor (200), such as, for example, a battery eliminator adaptor, a hands-free adaptor, or a mobile transceiver adaptor. The operating mode of por-table telephone (100) also automatically changes when it is coupled to or decoupled from vehicular adaptor (200) during a cellu-lar telephone call. For example, when vehicular adaptor (200) is plugged into portable telephone (100), the portable display (116) is not disabled when inactive for a predetermined time.
