Problem Solving

■

Make sure you’re within about 32 feet (10 m) of the projector, and the remote control is 
aimed at the projector’s front or back sensor within the ranges shown below.

■

You may need to replace the remote control batteries (see page 22). Press the 

illumination button and check if the buttons glow. If they don’t, replace the batteries.

■

Dim the room lights and turn off any fluorescent lights. Make sure the projector is not in 
direct sunlight.

■

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

■

Make sure there are no objects between the remote control and the IR receiver.
