Maintenance

Your projector needs little maintenance. The only things you have to do on a regular basis are to keep the lens clean and to clean the dust filters to prevent overheating.

Never remove any parts of the projector except the lamp and dust filters. Contact your dealer if other parts need replacing.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

Use a canister of compressed air to remove dust.

If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner to gently wipe the lens surface.

Never rub the lens with abrasive materials.

Cleaning the projector case

Before you clean the case, turn the projector off 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. Then wipe the case.

Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.

Cleaning and replacing the dust filters

It is necessary to clean the dust filters periodically. If the filters are not cleaned, they can become clogged with dust and prevent proper ventilation. This can cause overheating and a malfunction of the projector.

A warning message like the one pictured to the right will be displayed for 10 seconds every 300 hours to remind you to clean the filters.

1.Turn the project off and wait until the fans stop running.

2.Disconnect the projector from any cables.

3.Open one dust filter cover from the right and another one from the front of the projector.
