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; see the following table for compatible formats. As 
noted below, some images are automatically resized to display in the 
projector’s “native” format (XGA). In addition, 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.
■Insert the projector’s three-wire grounding-type plug into a properly 
grounded outlet. If you have a two-prong outlet, contact an electrician 
to replace it. 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. 
						

							208Notices
■Never push objects of any kind through the cabinet slots. Never spill 
liquid of any kind into the projector.
■Except as specifically explained in this User’s Guide, do not attempt to 
service this product yourself. Refer all servicing to qualified personnel. 
Opening or removing covers may expose you to dangerous voltages and 
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 
consult your state and local regulations regarding proper disposal and do 
not place in the trash.
■Unplug the projector during lightning storms or when it will not be used 
for extended periods.
■Do not place the projector and/or remote control on top of 
heat-producing equipment or in a hot location.
■If you use the projector in a country other than where you purchased it, 
use the correct power cord for that country.
■Do not stand on the projector or place heavy objects on it.
■Do not use the projector outside of the required temperature range of 41 
to 95 °F (5 to 35 °C). Doing so may cause an unstable display and could 
lead to projector damage.
■Do not store the projector outside of the required temperature range of 
14 to 140 °F (-10 to 60 °C) or in direct sunlight for long periods of time. 
Doing so may cause damage to the case. 
						

							Notices209
Remote Control Information
You can operate the projector by remote control via a line-of-sight infrared 
(IR) receiver at the front and rear of the projector. The projector may not 
respond to remote control commands under the following conditions:
■There is an object between the remote control IR emitter and the IR 
receiver on the projector.
■Ambient light is too bright.
■Certain types of fluorescent lighting are used.
■A strong light source shines into the IR receiver.
■Other equipment that emits infrared energy, such as a radiant room 
heater, is in the room.
These conditions commonly cause problems for most infrared-controlled 
equipment. Try the following:
■The remote control’s batteries may be low on power; replace them.
■Dim the ambient lighting and/or turn off any fluorescent lights.
■Close any window coverings and/or move the projector out of direct 
sunlight.
■Turn off other equipment that emits infrared energy.
