Solving Problems With the Remote Control

■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 page 86.

■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.
