The remote control doesn't work. What should I do?

• Check the following:
  • Point the remote control towards the projector's receiver. Make sure you are within 19.7 feet (6 meters) of the projector and within a 30° horizontal angle and a 15° vertical angle from the projector's front or back receiver.
  • The remote control's batteries may not be installed correctly or may be low on power. To change the batteries, see Replacing the Remote Control Batteries.
  • Dim the room lights and turn off any fluorescent lights. Make sure the projector is not in direct sunlight. Strong lighting, especially fluorescent lights, may affect the projector's infrared receivers. Also, turn off any nearby equipment that emits infrared energy, such as a radiant room heater.
  • If any buttons are held for longer than 30 seconds, the remote enters sleep mode. Release any button that is held to wake the remote.
