Using the Projector Security Features
To prevent unauthorized use of the projector, you can:

projector from being turned on and prevent your custom startup 
screen from being changed. See the next section.
■Create a custom screen that is displayed at startup and/or when 
the 
A/V Mute button is pressed. The screen can be locked with a 
password to discourage theft and provides a way to identify the 
projector should it be stolen. See page 54. 
note
Do not use the projector at 
altitudes above 7,500 feet 
(2,286 meters).

Maintaining the Projector
Your projector needs little maintenance. All you have to do on a 
regular basis is clean the lens, and check that the air filter and vents are 
clean. A clogged air filter or vent can block ventilation needed to cool 
the projector.
The only parts you should replace are the lamp and air filter. If any 
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:
■Cleaning the lens
■Cleaning the projector case
■Cleaning the air filter
■Replacing the air filter
■Replacing the lamp
■Replacing the remote control batteries
■Transporting the projector
warning
Before you clean any part of 
the projector, turn it off and 
unplug the power cord. 
Never open any cover on the 
projector, except the lamp 
cover. Dangerous electrical 
voltages in the projector can 
injure you severely. Do not 
try to service this product 
yourself, except as specifically 
explained in this User’s 
Guide. Refer all other 
servicing to qualified service 
personnel. 
						

							58Maintaining the Projector
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
To remove dirt or smears on the lens, use a commercially available 
cloth for cleaning glasses.
Cleaning the Projector Case
Before cleaning, turn off the projector and unplug the power cord.
■To remove dirt or dust, wipe the case with a soft, dry, lint-free 
cloth.
■To remove stubborn dirt or stains, moisten a soft cloth with water 
and a neutral detergent and firmly wring the cloth dry. Then wipe 
the case.
Cleaning the Air Filter 
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter, clean it as described here. Dust clogs 
prevent proper ventilation and can cause overheating, which can 
damage the projector.
1. Turn off the projector and unplug the power cord.
2. Remove dust from the air filter using a small vacuum cleaner 
designed for computer or office equipment, or gently clean the 
vent with a soft brush (such as an artist’s paintbrush).
caution
Do not rub the lens with 
harsh materials or subject 
the lens to shocks, or you 
may damage it.
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case.
note
To order replacement air 
filters, request part number 
V13H134A13. See page 11 
for ordering information. 
						

							Maintaining the Projector59
You can remove the air filter to clean both sides
If the filter is too dirty or broken, replace the filter as described below. 
Replacing the Air Filter
You need to replace the air filter if:
■You cannot remove the dust from it
■The air filter is damaged or torn
■You repeatedly see a projected message telling you to clean or 
replace it
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766) to obtain a new air filter. Request part number 
V13H134A13.
1. Turn off the projector and unplug the power cord.
2. Slide the air filter out of its slot as shown.
3. Slide the new air filter into the slot until it clicks into place.
note
Air filters contain 
polycarbonate, ABS resin, 
and polyurethane foam. 
Dispose of used air filters 
according to local 
regulations. 
						

							60Maintaining the Projector
Replacing the Lamp
The life span of the projection lamp is about 3000 hours if 
Brightness Control in the Settings menu is set to High (default), and 
4000 hours if 
Brightness Control is set to Low. See page 63 to check 
the lamp usage.
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen and the 
Lamp light flashes orange. To maintain projector brightness 
and image quality, replace the lamp as soon as possible.
You may also need to replace the lamp if the 
Lamp light flashes or 
stays on red. See page 69.
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L41.
Follow these steps to replace the lamp:
1. Turn off the projector and, after the projector beeps twice, unplug 
the power cord.
2. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
note
Turn off this product when 
not in use to prolong the life 
of the projector. 
Lamp light
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury. If the projector has 
been installed on the ceiling, 
you should stand to the side 
of the lamp cover, not 
underneath it.
If the lamp is used after the 
replacement period has 
passed, the possibility that 
the lamp may break 
increases. When a lamp 
replacement message 
appears, replace the lamp 
with a new one as soon as 
possible, even if it is still 
working.
