Abstract
An electronic device is disclosed having a main body and being in communication with a remote controller capable of transmitting and receiving signals to and from the electronic device. The main body has a portable power supply and is controlled by the remote controller. The electronic device is composed of a power supply checking device that checks the status of the portable power supply when receiving a power supply checking signal from the remote controller. The remote controller has a liquid crystal display for displaying on the remote controller the status of the portable power supply in response to a status signal transmitted from the power supply checking device. Thus, the power supply status of the portable power source can easily be detected by the remote controller.
