Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 30. 
■Make sure you are within about 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 15° above or below).
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in di rect 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 he ater. To avoid interference, you 
can also turn off the projector’s front or back sensor with the 
Remote Receiver setting (see page 68), but this may limit where 
you can use the remote control.
■Make sure the projector’s sensors have not been turned off with 
the 
Remote Receiver setting (see page 68).
■If any buttons are held for longer than 30 seconds, the remote 
enters sleep mode. Release any butt on that is held to wake the 
remote. 
■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 
(see page 75).

Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a classroom or conference room.
The projector can be installed for fo ur different viewing setups: front 
projection, ceiling projection, rear  projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll ne ed the optional ceiling mounting 
hardware; see page 13 for ordering information. You’ll also need to 
select 
Front/Ceiling or Rear/Ceiling as the Projection option in the 
projector’s Extended menu to flip  the image upside-down. To project 
from the rear, onto a semi-transparent screen, select 
Rear or 
Rear/Ceiling (see page 74).
Front projectionRear projection
Rear/ceiling projectionCeiling projection 
						

							
106Projector InstallationIf you’re mounting the projector on the ceiling and you place it above 
screen level, you’ll have to tilt the projector down to position the 
image on the screen. This causes the image to lose its square shape. 
You can correct the distortion using the 
Keystone function in the 
projector’s menu system (see page 67).
If you place the projector so that the base of the lens is level with the 
bottom of the screen, the image should be square and you won’t have 
to adjust it. If you place the lens lower than the bottom of the screen, 
you’ll have to tilt the projector upward if you want to fill the whole 
screen with the image. 
The following illustrations provide measurements you can use when 
installing the projector:

Compatible Video Formats
The projector supports NTSC, PAL, and SECAM international video 
standards, as well as the monitor display formats listed below.
To project images output from a computer, the computer’s video card 
must be set at a refresh rate (vertica l frequency) that’s compatible with 
the projector. Some images are automatically resized using Epson’s 
SizeWise™ technology to display in the projector’s “native” format 
(XGA or WXGA). The frequencies of some computers may not allow 
images to display correctly; see your computer’s documentation for 
details.
