Glossary
This section explains easily terms that are used with the projector and difficult terms that are not explained in the text of this guide. For details, refer to 
other commercially available publications.
AMX Device Discovery
AMX Device Discovery is a technology developed by AMX to facilitate AMX control systems for easy operation of the target 
equipment.
Epson has implemented this protocol technology, and has provided a setting to enable the protocol function (ON).
See the AMX Web site (www.amx.com) for more details.
DHCP
An abbreviation of Dynamic Host Configuration Protocol, this protocol automatically assigns an IP Address to equipment 
connected to a Network.
HDCP
HDCP is an abbreviation for High-bandwidth Digital Content Protection. It is used to prevent illegal copying and protect 
copyrights by encrypting digital signals sent over DVI and HDMI ports. Digital images protected by HDCP technology can be 
projected with this projector because the projector's DVI-D and HDMI input ports are compatible with HDCP. However, the 
projector may not be able to project images protected with updated or revised versions of HDCP encryption.
HDTV
An abbreviation for High-Definition Television that refers to high-definition systems which satisfy the following conditions.
•Vertical resolution of 720p or 1080i or greater (p = Progressive, i = Interlace)
•Screen Aspect Ratio of 16:9
•Dolby Digital audio reception and playback (or output)
IP Address
A number to identify a computer connected to a Network.
S-Video
A Video signal which has the luminance component and color component separated to provide better image quality.
Refers to images that consist of two independent signals: Y (luminance signal) and C (color signal). 
SDTV
An abbreviation for Standard Definition Television that refers to standard television systems which do not satisfy the conditions 
for HDTV High-Definition Television. 
SNMP
An abbreviation for Simple Network Management Protocol, which is the protocol for monitoring and controlling devices such as 
routers and computers connected to a TCP/IP Network.
sRGB
An 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. If the connected source has an sRGB mode, set both the 
projector and the connected signal source to sRGB.
SVGA
A type of video signal with a resolution of 800 (horizontal) ^ 600 (vertical) dots that is used by IBM PC/AT-compatible computers. 
SXGA
A type of video signal with a resolution of 1,280 (horizontal) ^ 1,024 (vertical) dots that is used by IBM PC/AT-compatible 
computers.

VGA
A type of video signal with a resolution of 640 (horizontal) ^ 480 (vertical) dots that is used by IBM PC/AT-compatible computers. 
XGA
A type of video signal with a resolution of 1,024 (horizontal) ^ 768 (vertical) dots that is used by IBM PC/AT-compatible 
computers. 
Aspect Ratio(Aspect Ratio)The ratio between an image's 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. Interlace
A 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 top to bottom. The even-numbered lines and odd-numbered lines are displayed alternately. 
Gateway address(Gateway Address)This is a server (router) for communicating across a network (subnet) divided according to subnet masks.Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased 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. 
Component Video
A Video signal which has the luminance component and color component separated to provide better image quality.
Refers to images that consist of three independent signals: Y (luminance signal), Pb and Pr (color difference signals). 
Composite video
Video 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.
Subnet mask
(Subnet Mask)
This is a numerical value that defines the number of bits used for the network address on a divided network (subnet) from the IP 
address.
Sync.
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images are not of a good quality. The process of matching the phases of these signals (the relative position of the crests 
and the troughs in the signal) is called Synchronization. If the signals are not synchronized, flickering, blurriness, and horizontal 
interference occur. 
Tracking
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images are not 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 appear in the signal. 
Trap IP Address
This is the IP Address for the destination computer used for error notification in SNMP.
Dolby Digital
A 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 which adds to this a center speaker, two rear speakers, and a sub-woofer. 
Progressive
A method of image scanning whereby the image data from a single image is scanned sequentially from top to bottom to create 
a single image.  
						

							Glossary
164
Refresh Rate
The 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 to refresh the light-emitting element. The number of refresh operations per 
second is called the Refresh Rate and is expressed in hertz (Hz).

•Do not carry the projector by yourself. Two people should use the 
handles to carry the projector when unpacking or moving it.
•Do not place the projector on an unstable cart, stand, or table. When 
projecting images vertically, install the projector correctly and 
appropriately to prevent it from turning over and falling.
•Do not operate the projector on its side, while tilted to one side, or 
upside down. Do not tilt the projector forward or back at a greater 
angle than that specified for vertical keystone correction. sp.159
•If the projector is mounted on a ceiling, it should be installed by 
qualified technicians using mounting hardware designed for use with 
this projector. Also, when mounting the projector on the ceiling, make 
sure to pass a wire through the handles to prevent it from falling.
•If you use a ceiling mount and apply adhesives to the mount to prevent 
the screws from loosening, or if you use lubricants or oils on the 
projector, the projector case may crack and the projector may fall from 
its ceiling mount. This could cause serious injury to anyone under the 
mount and could damage the projector. When installing or adjusting a 
ceiling mount, do not use adhesives to prevent the screws from 
loosening and do not use oils or lubricants.
•Do not stand on the projector or place heavy objects on it.
•Do not use the projector where it may be exposed to rain, water, or 
excessive humidity.
•Unplug the projector from the wall outlet before cleaning. Use a dry 
cloth (or, for stubborn dirt or stains, a moist cloth that has been wrung 
dry) for cleaning. Do not use liquid, aerosol cleaners, or solvents such 
as alcohol, thinner or benzine.
•Do not use any spray containing a flammable gas to remove dirt or dust 
that is adhering to parts such as the lens or filter of the projector.
•Never spill liquid of any kind into the projector.
•Do not use the projector where it may be exposed to excessive dust or 
smoke.•Do not use the projector where it may be exposed to flammable, 
corrosive, or explosive gases. Because the lamp inside the projector 
becomes very hot during use, the gases may ignite and result in a fire.
•Never push objects of any kind through the cabinet slots or openings.
•Do not use or store the projector or remote control in a hot location, 
such as near a heater, in direct sunlight, or in a closed vehicle.
•Incorrect battery usage may cause leakage of battery fluid and battery 
rupture, which could result in fire, injury or corrosion of the projector. 
When replacing batteries, take the following precautions: Insert 
batteries so that the polarities (+ and -) are correct, do not use batteries 
of different types, do not mix old and new batteries, and do not use any 
batteries other than those specified in this User's Guide. Replace the 
batteries as soon as they run out and remove the batteries if you will not 
be using the projector for a long period of time. Do not expose batteries 
to heat or flame and do not put them in water. Dispose of used batteries 
according to local regulations. Keep these batteries out of the reach of 
children. Batteries are choking hazards and are very dangerous if 
swallowed. If the batteries leak, wipe away battery fluid with a soft 
cloth. If battery fluid gets on your hands, wash them immediately.
•Do not use or store the projector in places where high and low 
temperature extremes occur, or where the temperature can change 
suddenly.
•Do not set up the projector in places where it might be subjected to 
vibration or shock.
•Do not set up the projector near high-voltage electrical wires or sources 
of magnetic fields.
•Do not store the projector standing on its side.
•Do not block the slots and openings in the projector case. They provide 
ventilation and prevent the projector from overheating. If you are 
setting up the projector near a wall, leave at least 19.7 inches (50 cm) of 
space between the wall and the air exhaust vent.
