Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Make sure you are within 20 feet (6 m) of the projector, and 
within range of the projector’s front or back sensor. The effective 
range is approximately 30° to the left or right, 30° above or below 
the rear sensor, and 60° above the front sensor (below, if mounted 
upside-down).
■If a button on the remote control is held for more than 
30 seconds, the remote enters 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 51.
■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 60 for details.
■Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You have lost the remote control.
You need the remote control to access many projector features. If you 
have lost it, you can order another from Epson; see page 92 for details.
