Make sure you are within 20 feet of the projector, and within 
range of the projector’s front or back sensor (approximately 30° to 
the left or right and 15° above or below).

seconds, the remote enter sleep mode. Press another button for 
normal operation.

The remote control batteries may not be installed correctly or may 
be low on power. Replace the batteries as described on page 48.

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 page 56 for details.

■

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

You need the remote control to access many projector features. If you 
have lost it, you can order another from Epson. See page 88 for 
details.
