remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the 
rear of the projector, the remote will function well within a radius of about 7 meters (23 feet) and 15 
degrees above or below the projector level. If the projector does not respond to the remote control, move a 
little closer.
