■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 52 for information on creating 
your own startup screen. 
■Lock the projector with a password, or enable your iPod to act as a key. For more 
information, see page 54.
■Disable the projector’s buttons; this is useful, for example, in a classroom when you want 
to ensure that no one touches the projector’s buttons while you’re using the remote 
control. See page 53 for more information.

logo, slogan, photograph, or any other image you want to use. 
Note: When you choose an image for the user’s logo, it erases any previously used image. You

operation will be locked.” is displayed for approximately five minutes, and then the projector 
switches to standby mode. If this happens, disconnect the power cable from the electrical outlet 
and then reinsert it and turn the projectors power back on. The projector displays the password 
entry screen again so that you can enter the correct password.
If you continue to repeat the above operation and input the wrong password thirty times in 
succession, you see the message “The projectors operation will be locked. Contact Epson as 
described in your documentation.” and the projector will not accept any more password entries.

Maintenance
Your projector needs little maintenance. All you need to do on a regular basis is keep the lens 
clean. You also may need to clean the air filter to prevent overheating.
Warning: Before you clean any part of the projector, turn it off, unplug the power cord and let it 
cool down. Never open any cover on the projector, except the lamp and filter covers. 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. 
The only parts you should replace are the air filter and the lamp. If another part needs 
replacing, contact your dealer or a qualified servicer.
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. 
■Use a blower brush that is designed for camera equipment to remove dust from the lens.
■To remove dirt or smears, use a lens cloth or tissue. If necessary, moisten the cloth with 
lens cleaner and gently wipe the lens surface.
Caution: Never rub the lens with abrasive materials. Use only lens cleaning fluids that are designed 
for cleaning optics.
Cleaning the Projector Case
Before you clean the case, turn off the projector, unplug the power cord and let it cool down.
■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. Then wipe the case and dry it with a dry cloth.
Caution: Never use wax, alcohol, benzene, thinner, or other chemical detergents. These can 
damage the case.
Never spray any liquid of any kind on the projector. Always spray cleaner on a cloth and then wipe 
the projector. 
						

							Cleaning and Replacing the Air Filter59
Cleaning and Replacing 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 below. Dust clogs prevent proper ventilation and cause overheating 
and damage to the projector.
1. Press the Ppower button and wait for the Ppower light to stop flashing and for the 
projector to cool down.
2. Unplug the power cord and disconnect any cables. 
3. If using an iPod, remove the iPod and close the dock.
4. Turn the projector over (unless it’s ceiling mounted).
5. Lower the handle so you can access the air filter.
6. Pull the air filter cover straight up as shown. 
						

							60Maintenance
7. Use a small vacuum cleaner that is designed for computers and other office equipment to 
remove any dust from the surface of the filter. If you don’t have one, gently clean the 
filter using a very soft brush (such as a clean artist’s paintbrush).
If the dirt is difficult to remove or the filter is broken, replace it. You can purchase air 
filter part number V13H134A31 from an authorized Epson reseller. To find the nearest 
reseller, please call 800-GO-EPSON (800-463-7766). To purchase online, visit 
www.epsonstore.com (U.S. sales) or www.epson.ca (Canadian sales).
8. Insert the air filter as shown until it clicks into place.
