PURPOSE:To specify position of the body of a remote control device by making a switch provided in a body operated by the body of a remote control device to emit feeble radio waves, and making the body of the remote control device to receive the feeble radio waves and generate an acoustic signal. CONSTITUTION:The body of the remote control device 15, a container 12 and a switch 13 are provided in front of a body, for instance a television 10, to be operated by the body of the remote control device 15. The body of the remote control device 15 is taken out from the container 12, and the television set 10 is remote controlled by controlling off/on of a power source, and operating a volume adjusting switch (b) and channel selection switches 1-12. When the switch 13 of the television set 10 is depressed, feeble radio waves are emitted. The body of the remote control device 15 detect this and generates an acoustic signal from a speaker 17 and informs of the position of presence. Thus, unknown position of the body of the remote control device 15 can be found easily. |
