The RCA D930 is an infrared receiver used in conjunction with remote controls. The receiver can accept remote control commands from an even greater distance than the RF signal provided by a remote control. To connect this receiver to your television, you need to install the infrared transmitter and place the receiver near your television. The infrared signal will take care of the rest.
Plug the receiver into an electrical outlet near your television.
Place the receiver in the same room as your television, making sure the logo side of the receiver faces the television.
Press the "Power" button on your remote control while pointing it at the receiver. The signal will travel through the receiver and into your television.
