Maintenance
*The projector needs little maintenance. You should keep the lens clean because any dirt or stains may appear
on the screen. You will also need to clean the air filter attached at the bottom of the projector periodically
because a clogged air filter prevents proper ventilation that is necessary to cool the projector and prevents it
from overheating. If any parts need to be replaced, contact your dealer. When cleaning any part of the pro-
jector, always turn the power off and unplug the projector first.
Cleaning the lens
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface of it. Wipe the lens surface gently with an air
spray or 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 wipe the lens
surface gently.
Cleaning the Projector Case
Cleaning the Projector Case
To clean the projector case, first unplug the power cable. To remove dirt or dust, wipe the casing with a soft,
dry, lint-free cloth. To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent
and then wipe the casing.
Do not use alcohol, benzene, thinners or other chemical detergents as these can cause the casing to be
warped.
Cleaning the
Cleaning the Air Filter
Air Filter
The air filter, which is located at the bottom of the projector, should be cleaned after every 100 hours’ use.
If it is not cleaned periodically, it can become clogged with dust and prevent the projector from being ventilat-
ed properly. This may cause overheating and damage of the projector.
To clean the air filter :
1. Switch the projector off and unplug the power cable from the wall socket.
2. Stand the projector on it’s side so that the handle can be at the top, and you can easily access the
air filter.
3. Push the opening tip of the air filter cover and remove the cover.
4. The air filter is inside the cover. To clean the filter, use a small vacuum cleaner designed for com-
puters or other office equipment. If not, you may use a dry, lint-free cloth. If it is difficult to remove
dirt or the filter is torn, contact your dealer or the service center to replace it.
5. Close the filter cover after cleaning.
6. Plug the power cable back into the wall socket.
