Glossary
Following is an explanation of some of the terms used in this guide that may be unfamiliar or that were not 
explained in the text of this guide. Further information can be obtained by referring to other commercially-
available publications.
Aspect ratioThe ratio between an images length and its height. HDTV images have an aspect ratio of 
16:9 and appear elongated. The aspect ratio for standard images is 4:3.
Color temperatureThe temperature of an object which is emitting light. If the color temperature is high, the 
colors tend to take on a bluish tinge. If the color temperature is lower, the colors tend to 
take on a reddish tinge.
Component videoVideo signals that have the video brightness signals and color signals separated, in order 
to provide better image quality. 
In high-definition TV (HDTV), it refers to images which consist of three independent 
signals: Y (luminance signal), and Pb and Pr (color difference signals).
Composite videoVideo signals that have the video brightness signals and color signals mixed together. 
The type of signals commonly used by household video equipment (NTSC, PAL and 
SECAM formats). 
The carrier signal Y (luminance signal) and chroma (color) signal that are contained in 
the color bar are overlapped to form a single signal.
ContrastThe relative brightness of the light and dark areas of an image can be increased or 
decreased in order to make text and graphics stand out more clearly, or to make them 
appear softer. Adjusting this particular property of an image is called “contrast 
adjustment.”
Cool-downThe cooling process for the projectors lamp unit continues even after the [Power] button 
on the projectors control panel or the remote control has been pressed to turn off the 
projector. After the lamp turns off, the cooling fan continues operating, but all button 
operations are disabled. The period of time during which this happens is called the “cool-
down period.” The cool-down period lasts for about 25 seconds. The actual time varies 
depending on the external air temperature.
Dolby DigitalA sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format 
that uses two speakers. Dolby Digital is a 6-channel (5.1-channel) system that adds to 
this a center speaker, two rear speakers and a sub-woofer.
HDTVAn abbreviation for High-Definition Television. It refers to high-definition systems that 
satisfy the following conditions.
Vertical resolution of 720p or 1080i or greater (p = progressive scanning
, i = interlaced 
scanning)
Screen aspect ratio
 of 16:9
Dolby Digital
 audio reception and playback (or output)
Interlaced scanningA method of image scanning whereby the image data is divided into fine horizontal lines 
that are displayed in sequence starting from left to right and then from the top to the 
bottom of the screen. The even-numbered lines and odd-numbered lines are displayed 
alternately.
Progressive 
scanningA method of image scanning whereby the image data from a single image is scanned 
sequentially from top to bottom to create a single image.
Refresh rateThe light-emitting element of a display maintains the same luminosity and color for an 
extremely short time. Because of this, the image must be scanned many times per second 
in order to refresh the light-emitting element. The number of refresh operations per 
second is called the “refresh rate,” and is expressed in hertz (Hz).
Resize displayThis function is used to project computer images that have a resolution of more than or 
less than the projectors panel resolution, so that they fill the whole projection area.
SDTVAn abbreviation for Standard Definition Television. It refers to standard television 
systems that do not satisfy the conditions of High Definition Television.
Security lockA device consisting of a projector case with a hole in it that a commercially-available 
theft-prevention cable can be passed through in order to secure the device to a table or 
pillar. This projector is compatible with the Microsaver Security System manufactured 
by Kensington.
sRGBAn international standard for color intervals that was formulated so that colors that are 
reproduced by video equipment can be handled easily by computer operating systems 
(OS) and the Internet.

SVGAA type of video signal with a resolution of 800 (horizontal) x 600 (vertical) dots that is 
used by IBM PC/AT-compatible computers.
S-VideoA video signal that has the luminance component and color component separated in 
order to provide better image quality.
It refers to images that consist of two independent signals: Y (luminance signal), and C 
(color signal).
Sync.
(Synchronization)The signals output from computers have a specific frequency. If the projector frequency 
does not match this frequency, the resulting images will not be of a good quality. The 
process of matching the phases of these signals (the relative position of the crests and 
troughs in the signal) is called “synchronization.” If the signals are not synchronized, 
problems such as flickering, blurriness and horizontal interference can occur.
TrackingThe signals output from computers have a specific frequency. If the projector frequency 
does not match this frequency, the resulting images will not be of a good quality. The 
process of matching the frequency of these signals (the number of crests in the signal) is 
called “tracking.” If tracking is not carried out correctly, wide vertical stripes will appear 
in the projected image.
VGAA type of video signal with a resolution of 640 (horizontal) x 480 (vertical) dots that is 
used by IBM PC/AT-compatible computers.
XGAA type of video signal with a resolution of 1024 (horizontal) x 768 (vertical) dots that is 
used by IBM PC/AT-compatible computers.
YCbCrThe carrier signal that is contained in the color bar signal used in modern TV 
transmissions. The name comes from the Y (luminance) signal and the CbCr (chroma 
(color)) signals.
YPbPrThe carrier signal that is contained in the color bar signal used in high-definition TV 
(HDTV) transmissions. The name comes from the Y (luminance) signal and the PbPr 
(color difference) signals.

Warranty
Basic One-Year Warranty and 90-Day Lamp Warranty
What Is Covered: Epson America, Inc. (“EPSON”) warrants to the first end user customer of the EPSON 
product enclosed with this limited warranty statement that the product, if purchased and used 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 one (1) year from the date of original purchase (except that the 
warranty period is 90 days for projector lamps). 
What EPSON Will Do To Correct Problems: If you elect carry-in warranty service, please bring the product 
securely packaged in its original container or an equivalent, along with proof of the date of original purchase, 
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 
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. Exchange or replacement products 
or parts assume the remaining warranty period of the product covered by this limited warranty. However, 
each replacement lamp carries the limited 90-day warranty stated above.
What This Warranty Does Not Cover: This warranty covers only normal consumer use in the United States 
and Canada. For lamps, 24-hour-per-day use causes unusual strain and is not considered normal use. This 
warranty does not cover consumables (e.g., fuses), other than lamps. 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 
PRODUCTS 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.
