Selected FAQ

Q:
The remote control doesn't work. What should I do?
A:
Check the following:

  • Point the remote control towards the receiver.


  • Make sure the projector and remote control IDs match. To operate all projectors by remote control regardless of ID settings, set the ID switch on the side of the remote control Off.


  • The remote control batteries may not be installed correctly or may be low on power. To change the batteries, see Replacing the Batteries.


  • Make sure you are within 49 feet of the projector, and within range of the projector's front or back sensor.


  • 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 necessary, use the Remote Receiver setting to disable the projector's front or back sensor if it continues to pick up interference. See Customizing Projector Features.


  • Make sure the Remote Receiver setting isn't disabling both of the projetor's sensors. See Customizing Projector Features.


  • If the buttons are held for more than 30 seconds, the remote enters sleep mode. Release any button that is held to wake the remote.


  • Make sure the Remote Control Type setting is correct. See Customizing Power and Operation.
