Customizing Projector Features
You can use the Settings menu to lock the buttons on the projector, 
adjust audio volume, and customize several other features.
■Keystone

upward or downward. If you notice that lines or edge look jagged 
after adjustment, decrease the 
Sharpness setting (see page 47).
■Auto Keystone
Automatically compensates for keystone distortion when the 
projector is tilted upward or downward. This feature is available 
only when the projector is set for front projection (enabled by 
default).
■Control Panel Lock
Lets you disable all of the buttons on the projector, or all of the 
buttons except the Ppower button. See page 56 for more 
information.
■Power Consumption

Using the Projector Security Features
To prevent unauthorized use of the projector, you can:
■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. 
■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 56.
■Secure the projector to prevent theft using a cable locking system. 
See page 57.
Creating Your Own Startup Screen
You can transfer any image from your computer or video source to the 
projector and then use it as your startup screen. You can also use it as 
the screen displayed when the projector is not receiving a signal or 
when you press the 
A/V Mute button. The image can be a company 
logo, slogan, photograph, or any other image you want to use.

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. 
						

							60Maintaining 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 
V13H134A25. See page 15 
for ordering information.
