clear IR signal reception, aim the hand-held remote control toward the top of the IR
Sensor enclosure.

Position the IR Emitter as close as possible to the source’s IR Sensor (i.e. DVD,
Blu-ray, or media player). For a clear IR signal reception, the IR Emitter may be
affixed to the source’s IR Sensor. The IR Emitter’s signal is transmitted from the
side of the enclosure.
