It can prevent consumption and solve the problem that the operation state of the device becomes unstable due to incorrectly selected duplicate key selection.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

FIG. 2 is a diagram showing the main configuration of a television receiver equipped with a remote controller misoperation status alarm function according to an embodiment of the present invention. Referring to the same elements as those shown in FIG. The numbers are given and detailed description is omitted.

In Fig. 2, reference numeral I denotes a remote control device, and II denotes a main body of a television receiver remotely controlled by the remote control device I. In the inside of the remote control device I, predetermined control from the remote control IC 10 is performed.
