DU8190Z DLP Projector - User Manual
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 10 meters (25 feet) and 15 degrees above or below the projector
level. If the projector does not respond to the remote control, move a little closer.
