Important Safety Information
Follow these safety instructions when setting up and using the projector:
■Except as specifically explained in this User’s Guide, do not attempt to service this product 
yourself. Refer all servicing to qualified service personnel.
■Never open any cover on the projector, except the lamp and filter covers. Dangerous electrical 
voltages inside the projector can severely injure you.
■The projector and its accessories come packaged in plastic bags. Keep plastic bags away from small 
children to avoid any risk of suffocation.
■Never look into the projector lens when the lamp is turned on; the bright light can damage your 
eyes. Never let children look into the lens when it is on.
■Don’t place the projector on an unstable cart, stand, or table. Also, don’t stand on the projector or 
place heavy objects on it.
■Never push objects through the cabinet slots or spill liquid into the projector.
■Do not use the projector near water or sources of heat.
■Use a damp cloth for cleaning. Do not use liquid or aerosol cleaners. Unplug the projector from 
the wall outlet before cleaning. 
■Never try to remove the lamp immediately after use. Doing so will result in serious burns. Before 
removing the lamp, turn off the projector and wait for the lamp to cool completely.
■The lamp is fragile and can easily break. If the lamp breaks, handle the projector with extreme care 
to avoid injury from broken glass. If the projector is mounted to a ceiling, take it down before 
replacing the lamp, or pieces of broken glass could fall into your eyes or mouth.
■Do not use the lamp after the lamp replacement period has elapsed, because the possibility of lamp 
breakage increases. When the lamp replacement message appears, replace the lamp with a new one 
as soon as possible.
■This product includes a lamp component that contains mercury. Please consult your state and 
local regulations regarding disposal or recycling. Do not place in the trash.

							Specifications and Notices43
■The lamp in this projector is under high internal pressure and may make a loud noise if it breaks. 
If it breaks, ventilate the room to prevent mercury gas inside the lamp from being inhaled or 
coming into contact with the eyes or mouth.
■Do not bring your face close to the projector while it is in use, to prevent inhaling or contact with 
the gases inside the lamp if it breaks.
■If the lamp breaks and gas from the lamp or fragments of broken glass are inhaled or get into the 
eyes or mouth, or if any other ill effects are noticed, immediately seek medical advice.
■Use the type of power source indicated on the projector. If you’re not sure of the power available, 
consult the power company.
■If you use the projector in a country other than where you purchased it, use the correct power cord 
for that country.
■Place the projector near a wall outlet where the plug can be easily unplugged.
■Don’t place the projector where the cord can be walked on. This may result in fraying or damage 
to the plug.
■Don’t insert the plug into an outlet with dust present, and insert the plug firmly into the outlet. 
Failure to do so could result in sparks or fire. 
■Don’t handle the plug with wet hands.
■Don’t overload wall outlets, extension cords, or integral convenience receptacles. This can cause 
fire or electric shock.
■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 doesn’t 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.
■If there is an electrical storm, do not touch the power plug, otherwise you may receive an electric 
shock.
■Keep the projector unplugged when not in use for extended periods.
■Keep the batteries for the remote control out of the reach of children. Batteries are choking hazards 
and can be very dangerous if swallowed. If they are swallowed, seek medical attention immediately.
■Replace the batteries as soon as they run out. 
■Do not expose batteries to heat or flame. 
■Dispose of used batteries according to local regulations.
■Remove the batteries if you won’t be using the projector for a long period of time.
■Don’t block the slots and openings in the projector case. They provide ventilation and prevent the 
projector from overheating. Don’t operate the projector on a sofa, rug, or other soft surface, or in a 
closed-in cabinet unless proper ventilation is provided.
■Material or paper may get stuck against the air filter underneath the projector while it is in use. 
Remove anything from underneath the projector that might get stuck against the air filter in this 
way. 
						

							44Specifications and Notices
■Don’t place the projector or remote control on top of heat-producing equipment or in a heated 
place, such as a car.
■Don’t use the projector outside of the required temperature range (see page 40). Doing so may 
cause an unstable display and could lead to projector damage.
■Don’t store the projector outside of the required temperature range (see page 40) or in direct 
sunlight for long periods of time. Doing so may cause damage to the case.
WARNING: The cord included with this product contains chemicals, including lead, known to the 
State of California to cause birth defects or other reproductive harm. Wash hands after handling.

Epson America, Inc. Limited Warranty
What Is Covered: Epson America, Inc. (“Epson”) warrants to the original end user customer that the 
Epson product enclosed with this limited warranty statement, if purchased new and operated only in 
the United States or Canada, conforms to the manufacturer’s specifications and will be free from 
defects in workmanship and materials for a period of two (2) years from the date of original purchase 
(except that the warranty period is 90 days for projector lamps). For warranty service, you must provide 
proof of the date of original purchase.
What Epson Will Do To Correct Problems: Should your Epson projector require service during the 
warranty period, Epson will, at its option, exchange or repair the projector without charge for parts or 
labor. If Epson authorizes an exchange for the defective unit, Epson will ship a replacement projector to 
you, freight prepaid, to an address in Canada or the U.S. (excluding Puerto Rico and U.S. Possessions). 
Shipments to other locations will be made freight collect. You are responsible for securely packaging 
the defective unit and returning it to Epson within five (5) working days of receipt of the replacement. 
Epson requires a debit or credit card number to secure the cost of the replacement projector in the 
event that you fail to return the defective one. If your projector is being repaired by carry-in warranty 
service, please bring the product securely packaged in its original container or an equivalent to your 
Epson Dealer or Epson Customer Care Center. Epson will, at its option, repair or replace on an 
exchange basis the defective unit, without charge for parts or labor. When warranty service involves the  
						

							46Specifications and Notices
exchange of the product or of a part, the item replaced becomes Epson property. The exchanged 
product or part may be new or previously repaired to the Epson standard of quality, or, at Epson’s 
option, may be another model of like kind and quality. Exchange or replacement products assume the 
remaining warranty period of the product covered by this limited warranty, except that each 
replacement lamp carries the limited 90-day warranty stated above.
What This Warranty Does Not Cover: This warranty covers only normal use of the product in the 
United States and Canada. 24-hour-per-day use of this product causes unusual strain and is not 
considered normal use. This warranty does not cover consumables (e.g., fuses), other than lamps. This 
warranty does not apply to refurbished or reconditioned products, and this warranty is not transferable. 
Epson is not responsible for warranty service should the Epson label or logo or the rating label or serial 
number be removed or should the product fail to be properly maintained or fail to function properly as 
a result of misuse, abuse, improper installation, neglect, improper shipping, damage caused by disasters 
such as fire, flood, and lightning, improper electrical current, software problems, interaction with 
non-Epson products, or service other than by an Epson Authorized Servicer. Postage, insurance, or 
shipping costs incurred in presenting your Epson product for carry-in warranty service are your 
responsibility. If a claimed defect cannot be identified or reproduced in service, you will be held 
responsible for costs incurred. 
THE WARRANTY AND REMEDY PROVIDED ABOVE ARE EXCLUSIVE AND IN LIEU OF 
ALL OTHER EXPRESS OR IMPLIED WARRANTIES INCLUDING, BUT NOT LIMITED TO, 
THE IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR 
PURPOSE. SOME LAWS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES. 
IF THESE LAWS APPLY, THEN ALL EXPRESS AND IMPLIED WARRANTIES ARE LIMITED 
TO THE WARRANTY PERIOD IDENTIFIED ABOVE. UNLESS STATED HEREIN, ANY 
STATEMENTS OR REPRESENTATIONS MADE BY ANY OTHER PERSON OR FIRM ARE 
VOID. EXCEPT AS PROVIDED IN THIS WRITTEN WARRANTY, NEITHER EPSON 
AMERICA, INC. NOR ITS AFFILIATES SHALL BE LIABLE FOR ANY LOSS, 
INCONVENIENCE, OR DAMAGE, INCLUDING DIRECT, SPECIAL, INCIDENTAL OR 
CONSEQUENTIAL DAMAGES, RESULTING FROM THE USE OR INABILITY TO USE THE 
EPSON PRODUCT, WHETHER RESULTING FROM BREACH OF WARRANTY OR ANY 
OTHER LEGAL THEORY. IF THE REMEDY ABOVE FAILS, EPSON’S ENTIRE LIABILITY 
SHALL BE LIMITED TO A REFUND OF THE PRICE PAID FOR THE EPSON PRODUCT 
COVERED BY THIS LIMITED WARRANTY.
In Canada, warranties include both warranties and conditions.
Some jurisdictions do not allow limitations on how long an implied warranty lasts, and some 
jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the 
above limitations and exclusions may not apply to you. This warranty gives you specific legal rights, 
and you may also have other rights, which vary from jurisdiction to jurisdiction.
