Abstract
An apparatus for controlling a plurality of electrical devices, each of the electrical devices including circuitry for switching the electrical device to a standby mode or an operational mode. A main control unit and a secondary control unit is provided in each of the electrical devices. When a main control unit of one electrical device is connected to a secondary control unit of a second electrical device, control of the operational state of the second electrical device is transferred to the remotely located first electrical device. When the two electrical devices are disconnected, local control of the second electrical device is maintained.
