Maintenance
The projector needs little maintenance. You should keep the lens clean 
as dust, dirt or spots will project on the screen and diminish image 
quality. You will also need to clean the air filter located at the bottom 
of the projector periodically. It is important to keep the air filter clean 
because a clogged air filter prevents proper ventilation which is 
necessary to cool the projector and prevent it from overheating. The 
only part you should replace yourself are the lamp and the air filter. If 
any other parts need replacing, contact your dealer or qualified service 
personnel. When cleaning any part of the projector, always switch off 
and unplug the projector first.
Warning: Never open any of the covers on the projector 
except the lamp and air filter covers. Dangerous electrical 
voltages inside the projector can cause severe injury. 
Except as specifically indicated in this Instruction Manual, 
do not attempt to service this product yourself. Refer all 
servicing to qualified service personnel.
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. Wipe 
the lens surface gently with a soft, dry, lint-free cloth. To remove dirt or 
stains on the lens, moisten a soft cloth with water and a neutral 
detergent and gently wipe the lens surface.
Cleaning the Projector Housing
To clean the projector housing, first unplug the power cable. To 
remove dirt or dust, wipe the housing 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 housing. Do not use alcohol, 
benzene, thinners or other chemical detergents as these can cause 
damage to the housing.
Cleaning the Air Filter
The air filter, which is located at the bottom of the projector, should be 
cleaned after every 100 hours of use. If it is not cleaned periodically, it 
can become clogged with dust and prevent the projector from being 
ventilated properly. This can cause overheating and damage the 
projector.

To clean the air filter:
1 Switch the projector off and unplug 
the power cable from the wall 
socket.
2 Place a protective sheet (cloth) 
beneath the projector. Turn the 
projector over so you can see its 
underside.

filter tab.
4 Clean the air filter.
Caution: To clean the filter, you are advised to use a small vacuum 
cleaner designed for computers and other office equipment.
If the dirt is difficult to remove or if the filter is torn, replace it.
5 Replace the filter.
6 Plug the power back into the projector.
Note: Be sure that the projector is stable after turning it over. 
When replacing the filter, make sure it is inserted in the correct 
direction as shown illustration.
Replacing the Lamp
The projector lamp used for the light source has a certain life. It is time 
to replace them lamp when:
The lamp dims, the projected image gets darker or starts to 
deteriorate.
The projector lamp LED indicator turns to red (See page 14).
Caution: The lamp becomes high temperature after turning off 
the projector with the power button. If you touch the lamp, you 
may scald your finger. When you replace the lamp, wait for at 
least an hour for the lamp to cool. Be sure to turn off the 
projector and unplug the power cord before replacing the lamp.
