Care of the projector
Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts needs replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. Before you attempt to clean the lens, turn the
projector off, unplug the power cable, and leave it several minutes to cool completely.
1. Use a canister of compressed air to remove dust. (Available from building hardware or photographic
suppliers.)
2. If there is stubborn dirt or smudge marks, use a proper photographic lens brush or moisten a clean soft
lens cloth with lens cleaner to gently wipe the lens surface.
Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can
damage the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution.
Do not attempt to clean the lens whilst the projector is switched on or is still hot from previous use.
Cleaning the projector case
Before you attempt to clean the case, turn the projector off, unplug the power cable, and leave it several minutes
to cool completely.
1. To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
2. 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 filter
It is necessary to clean the dust filter periodically. You can go to Setup> Dust Filter Hours to check how long the
filter has been used. If the filter is not cleaned, it can become clogged with dust and prevent proper ventilation.
This can cause overheating and a malfunction of the projector.
In case you fail to clean the filter regularly, the projector
will shut down automatically once the filter is seriously
clogged with dust and cause over-heating inside of the
projector. You will see the message pictured to the right
before the power off.
To clean the filter,
1. Turn the project off and wait until the fans stop running.
2. Disconnect the projector from any cables.
3. Draw the dust filter grill from the front-right side of the projector.
Please install a new filter.
The projector will turn off in 1 min.
