Some equipment marks the location of the IR receiving Eye in the wrong place. Use flashlight to confirm location for the Hot Link Pro Emitter pad. Sony STR, Motorola Set top HDTV models often have the Eye on the exact opposite side as marked. Harmon Kardon AVR series Eye is not as marked but to the right and online with the five black buttons within the plastic black panel. For HR20 and Scientific Atlanta 8300 boxes, the Emitter may need to be placed adjacent to the receiver Eye or on top of 3 to five layers of beige masking tape.
