PURPOSE:To attain the sure control of load by receiving radio signals of a transmitter by a slave device set near the transmitter. CONSTITUTION:A control switch corresponding to a load 2 or a sound generating device 3 to be operated by a transmitter 1 is operated and radio signals are produced in response to the operation of a control switch. These radio signals are received by a receiving circuit 9 of a slave device 4 and outputted to a remotecontrolled IC 10. The IC 10 supplies the output of the circuit 9 through an SDI terminal to convert it into a command signal and outputs this command signal to a power line 5 from a SDO terminal via a power line transport circuit 11. Then the command signal is received by a transmission/reception circuit 8 of a master device 6 and then outputted to a control signal generating circuit 7. Then the circuit 7 produces a control signal containing an intrinsic address number and an action instruction of the device 4 or the device 3 in response to the contents of the command signal and transmits the control signal to the line 5 via the circuit 8.
