Note: The remote control can only interface with a computer when the projector is connected to the computer through a USB cable connection. The computer cable connects a computer to the projector for display purposes only.

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 (33 feet) and 30 degrees above or below the projector level. If the projector does not respond to the remote control, move a little closer.
