My remote control does not work. What should I do?

• Make sure you are within 30 feet of the projector, and within range of the projectors front or back sensor (approx. 30 degrees to the left or right and 15 degrees above or below). Try replacing the batteries. The lighting in the room may be affecting the infrared signal from reaching the projector properly. Turn off any fluorescent lights or dim the room lights. Turn off any nearby sources that emit infrared energy, such as a radiant room heater.
