Electric light line table tap socket built-in type transmitter with a switch Modulation system Narrow band width frequency modulation (maximum frequency deviation +-10Khz) High frequency output 3mW or less.

The thing beyond 500W should not use the home electronics connected with a socket. Apparatus, such as an electric heater, may generate heat in a socket portion, and an internal transmitter may damage it.

Please do not attach a magnet in a main part. An electric wave does not become weak or it stops coming out.
