Remote Control Operating Range 
The remote control uses infrared transmission to control the projector. It is not necessary to point 
the 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.
