Abstract
A car phone can be run from the battery of a vehicle in which it is mounted or from its own battery. If the vehicle ignition switch is turned off during communication, interrupting the supply of electric power from the vehicle battery, communication can continue because the internal power supply is automatically switched in. The phone has a speaker capable of emitting a key-click sound. A setting device sets the volume of the key-click sound. A controller is operative when communication is not in progress for adjusting the key-click sound to the volume set by the setting device. The controller is operative when communication is in progress for adjusting the key-click sound to a volume set by the setting device if the volume set by the setting device is equal to or less than a predetermined volume and for adjusting the key-click sound to the predetermined volume if the volume set by the setting device is greater than the predetermined volume.
