							 Cleaning the Projector, Cleaning the Lens, Cleaning the Air Filter - 89
Cleaning the Air Filter
Air ventilation will deteriorate and the internal temperature of the projector will rise if the Air 
Filter becomes blocked with dirt and dust, and this may result in damage.
Ensure that the projector is stood on its end and the Air Filter cleaned with a vacuum cleaner to 
prevent the dirt and dust from penetrating inside.
Point
·If it is no longer possible to remove the dirt from the Air Filter or it begins to crack, it is time 
to replace it. Contact your dealer in this event.
·A replacement air filter is packaged with the replacement lamp. Replace the Air Filter at 
the same time as replacing the lamp.

							 Replacing the Lamp - 91
Replacing the Lamp
Replace the lamp at the following times (model number: ELPLP11).
When a message stating [Lamp Replace] is displayed for thirty seconds after 
the start of projection
When the lamp indicator is blinking in orange
When the brightness and picture quality has deteriorated below the initial 
levels
Point
·Replace the lamp when it will not light up even if it is not time for replacement.
·Replace the lamp as quickly as possible after the message has been displayed to main-
tain the initial brightness levels and picture quality.
·The replacement message has been set at approximately 2,000 hours of use in order to 
maintain the initial brightness levels and picture quality.
·Although the replacement message is displayed after approximately 2,000 of use, there 
are cases where the individual characteristics of each lamp and other usage conditions 
result in it not lighting up before this 2,000 hours has elapsed. For this reason, always pre-
pare a replacement lamp well in advance.
·Replacement lamps are available from Epson OA Supplies Inc.
·Order your lamps from freedial (0120) 251-528 or purchase them from your nearest 
Epson dealer.
Lamp Replace
The lamp indicator will blink in orange. 
						

							92 - Replacing the Lamp
Replacement method

							96 - Transportation
Transportation
The projector contains many glass and precision parts. Ensure that the following precautions 
are observed to prevent the projector from being damaged by impact during transportation.

 When sending the projector to the manufacturer for repairs, etc.
·Use the box in which the projector was packed at the time of purchase.
·If the box is no longer available, protect the projector by wrapping it in shock-proof material 
to prevent impact, and then place it in a strong cardboard box for transportation purposes.

 When transporting repeatedely
·Place the projector in the optional Hard Travel Case (ELPKS15) and clearly mark that it is a 
precision instrument for the delivery people, and then request transportation.

							 Terminology - 97
Terminology
This section provides simple explanations for the terminology used within the manual, items 
for which explanations are not available, and other complex processes.
A/V Mute Temporarily erases the image and sound. The sound and image can be muted 
by pressing the [A/V Mute] button on the projector. Press the [A/V Mute] 
button once again or adjust the volume or display the menu to cancel the mute 
mode.
DVI-D port The input port that supports DVI ratings and that is one of the types of com-
pression/playback technologies for digital audio.
D output port The output port for digital tuners that support the new digital broadcasts 
within Japan.
Remote port Enables the optional remote control receiver to be connected so that multiple 
items of equipment can be operated with a remote control unit.
SRS The three-dimensional acoustic system. This enables wide and deep sound to 
be listened to. These are adjusted with the [Space] (wide) and [Center] (deep) 
buttons.
SVGA IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pix-
els and 600 vertical pixels.
SXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal 
pixels and 1,024 vertical pixels.
Sync(synchronization) Outputs computer signals at a pre-determined frequency. The image will not 
be projected clearly unless this frequency is aligned with the frequency of the 
projector. Aligning the signal phasing is known as synchronization. Projected 
images will be subject to distrubance, blurring and horizontal noise if not syn-
chronized.
VGA IBM PC/AT compatible (DOS/V equipment) signals with 640 horizontal pix-
els and 480 vertical pixels.
XGA IBM PC/AT compatible (DOS/V equipment) signals with 1,024 horizontal 
pixels and 768 vertical pixels.
USB An abbreviation for Universal Serial Bus. This is an interface for connecting 
comparitively low frequency equipment to the computer.
UXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,600 horizontal 
pixels and 1,200 vertical pixels.
Color temperature The temperature of the subject that emits light. A blue hue is attained when 
the color temperature is high, and a red hue is attained when the color temper-
ature is low.
Color differential signal Video equipment transmits signals through three cables as Red-Bright (R-Y), 
Bright (Y) and Blue-Bright (B-Y). This enables the composite signals (the red, 
green and blue signals and their brightness signals are transmitted along one 
cable) to be projected more clearly.
Operating system The software necessary to operate the computer. The EMP Link V supplied 
with the projector operates the computers with the use of the Windows 95 
(Japanese version) operating system, the Windows 98 (Japanese version) oper-
ating system, the Windows NT 4.0 (Japanese version) operating system, the 
Windows 2000 (Japanese version) operating system, and the Macintosh Kanji 
Talk 7.5.5 or higher operating systems. 
						

							98 - Terminology
Cool-down A lamp cooling procedure continues to operate even after the power supply 
has been switched off and the lamp extinguished. The cooling fan will begin 
to operate when the lamp is entinguished, and button operations will not 
longer be possible. This period is known as the cooling down period. The 
amount of time required for the cooling down procedure will differ in accor-
dance with the surrounding temperature.
Contrast By strengthening or weakening the tone of the colors, it is possible to project 
characters and pictures more clearly and attain a softer tint. This is known as 
contrast adjustment.
Stack projection Refers to the simultaneous duplicate projection of images with the use of mul-
tiple projectors in order to increase projection image brightness.
Theft-protection lock A threft-proof cable (available on the open market) is passed through the 
holes on the projector case to secure it to a desk or column. These holes sup-
port the Micro-Saver Security System manufactuered by Kensington Inc. The 
agency for this product within Japan is listed below.

projector. Aligning the signal frequency is known as tracking. Projected 
images will be subject to distrubance, blurring and horizontal noise if not syn-
