Selected FAQ

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

  • The remote control’s batteries may not be installed correctly or may be low on power. See Replacing the Batteries.


  • Make sure you are within about 20 feet (6 meters) of the projector and within range of the projector’s front sensor (approximately 60° to the left or right and 30° to 45° above or below) or back sensor (approximately 30° to the left or right and 30° above or below).


  • 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. If you still have trouble using the remote control, disable one of the remote receivers using the Settings menu to block interference from bright light. See Customizing Projector Features.


  • Turn off any nearby equipment that emits infrared energy, such as a radiant room heater.


  • Make sure at least one of the projector’s remote receivers (front or rear) are turned on in the Remote Receiver setting of the Settings menu. See Customizing Projector Features.


  • If the projector ID has been set, you may need to change the projector or remote control ID. See Operating Two or More Projectors with the Remote Control.


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