Microtek CX4 manual Cleaning the Lens, Cleaning the Projector Case, Cleaning the Air Filter

Cleaning the Lens

Any dirt or stains on the lens surface should be cleaned off immediately with a piece of soft, dry cloth not made of cotton or velvet material. You may also clean the projector by wiping gently the lens surface with a soft cloth moisten with a mixture of water and a neutral detergent.

Cleaning the Projector Case

Unplug the power cord of the projector before cleaning the projector case. Then, wipe away any dirt or stains with a soft, non-cotton or non-velvet cloth. If the dirt or stains are not able to be removed, use a cloth moisten with a mixture of water and a neutral detergent. Do not use any alcohol, benzene, thinners, or any other chemical detergents. They will cause damage or overheating to the projector.

Cleaning the Air Filter

The air filter located at the bottom of the projector should be cleaned once every 100 working days. Without regular cleaning, the projector will be blocked by dust, and it will cause the projector to overheat due to poor ventilation.

The Steps of Cleaning the Air Filter

1.Turn off the power and unplug the power cord.

2.Stand the projector up with the handle at the top so that easy access can be made to the air filter.

3.Take off the filter cover.

4.A small size vacuum cleaner for computer or office use can be used for cleaning the filter, or a piece of dry, non-cotton or non-velvet cloth can be used in the cleaning process.

Attention: If the clogged dirt is difficult to clean away or if the filter is old, a replacement of a new filter is required. Please contact the dealer of this projector for this part.

5.After the filter is cleaned, put it back to the original place, and put the filter cover on properly making sure the screws are secured.
