Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
The projector can be installed for four different viewing setups: front 
projection, ceiling mounting, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need 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 of 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 120).
Front projectionRear projection
Rear/ceiling projectionCeiling mounting 
						

							174Projector 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 113).
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.

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 (vertical frequency) that’s compatible with 
the projector. Some images are automatically resized to display in the 
projector’s “native” format (XGA). The frequencies of some 
computers may not allow images to display correctly; see your 
computer’s documentation for details.

Notices
This appendix includes safety instructions and other important information 
about your Epson PowerLite projector.
Important Safety Instructions
Follow these safety instructions when setting up and using the projector:
■Do not place the projector on an unstable cart, stand, or table.
■Do not use the projector near water or sources of heat.
■Use the type of power source indicated on the projector. If you are not 
sure of the power available, consult your dealer or power company.
■Place the projector near a wall outlet where the plug can be easily 
unplugged.
Placez l’appareil près d’une prise de courant où la fiche peut être débranchée 
facilement.
■Do not hold the plug with wet hands.
■Take the following precautions for the plug. Failure to comply with 
these precautions could result in sparks or fire: Do not insert the plug 
into an outlet with dust present. Insert the plug firmly into the outlet.
■Do not overload wall outlets, extension cords, or integral convenience 
receptacles. This can cause fire or electric shock.
■Do not place the projector where the cord can be walked on. This may 
result in fraying or damage to the plug.
■Unplug the projector from the wall outlet before cleaning. Use a damp 
cloth for cleaning. Do not use liquid or aerosol cleaners.
■Do not block the slots and openings in the projector case. They provide 
ventilation and prevent the projector from overheating. Do not operate 
the projector on a sofa, rug, or other soft surface, or in a closed-in 
cabinet unless proper ventilation is provided.
■Never push objects of any kind through the cabinet slots. Never spill 
liquid of any kind into the projector.

other hazards.
■Unplug the projector from the wall outlet and refer servicing to qualified 
service personnel under the following conditions: When the power cord 
or plug is damaged or frayed. If liquid has been spilled into the 
projector, or if it has been exposed to rain or water. If it does not operate 
normally when you follow the operating instructions, or if it exhibits a 
distinct change in performance, indicating a need for service. If it has 
been dropped or the housing has been damaged.
■This product includes a lamp component that contains mercury. Please
