PowerLite 84+ Multimedia Projector

Selected FAQ

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

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

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

  • The remote control batteries may not be installed correctly or may be low on power. See Replacing the 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. To avoid interference, you can also turn off the projector's front or back sensor with the Remote Receiver setting, but this may limit where you can use the remote control. See Customizing Projector Features.

  • Make sure the projector's sensors have not been turned off with the Remote Receiver setting. See Customizing Projector Features.

  • If you're using the remote control as a wireless mouse, make sure the USB Type B setting in the Extended menu is set to Wireless Mouse.
