Maintenance

The projector needs proper maintenance. You should keep the lens clean as dust, dirt or

spots will project on the screen and diminish image quality. 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. Dangerous electrical voltages inside the

projector can cause severe injury. Do not attempt to service this product yourself. Refer

all servicing to qualified service personnel.

Cleaning the Lens

Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands.

Cleaning the Projector Housing

Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth

damped with water, or water and neutral detergent, and wipe dry with a soft, dry cloth.

Cleaning the Filter Cover

The filter cover, which is located at the side 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 over heating and

damage the projector.

1. Switch the projector off and unplug the

AC power cord from the wall socket.

2. Remove the filter cover as the

illustration shown.

3. Clean the filter cover.

cleaner designed for computers and

other office equipment.
