Care and Replacement

Cleaning the projector

Before cleaning the projector

Disconnect the power cord plug from the wall outlet.

Unplug all the cables from the projector.

Cleaning the outer surface of the projector

Wipe off dirt and dust gently with a soft cloth.

If it is difficult to remove the dirt, soak a cloth in a neutral detergent diluted with water, wring the cloth well and then wipe the projector. Dry off the projector with dry cloth.

If you use a chemical treated wipe, follow the instructions supplied with it.

Cleaning the lens

Wipe off dirt and dust gently with a lint-free cloth.

Make sure no dirt or dust remains on the surface of the lens. It will be enlarged and projected onto a screen.

Cleaning the air filter

If the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector’s power will turn off (the TEMP indicator will flash after the power is turned off).

The air filter should be cleaned every 100 hours of use.

Use a vacuum cleaner to clean off any accumulated dust.

NOTE:

If the dust cannot be cleaned by a vacuum cleaner, remove the air filter and soak it in water, and then wash out the dust by hand. Be sure to install the air filter after it has dried.

Do not use detergent when washing the air filter.

If the dust cannot be removed by cleaning, it is time to replace the air filter. Please consult your dealer. Furthermore, if the lamp unit is being replaced, replace the air filter at this time also.
