sensor on a set-top box. When you are selecting TV channels in Windows Media Center, it enables the
remote control to work with your set-top box.

cable over the remote IR sensor (receiver) window on the set-top box (C). To locate the remote infrared
sensor window, shine a flashlight through the plastic on the front of the set-top box.
