Abstract
An automobile telephone device uses as its power source a battery for the automobile. This applies to an automobile telephone device with an automatic answering or receiving function. In the automobile telephone device, a voltage monitoring unit monitors the voltage of the battery. When the voltage falls near a limit voltage required for starting the automobile engine, the monitoring unit electrically interrupts a power source line connecting the battery and the telephone device via a proper switch circuit to thereby inhibit excessive consumption of the automobile battery by the automatic answering or receiving function during engine stoppage.
