Cleaning the Projector

Do not remove any covers or screws that are not mentioned in this manual. There are high voltage components inside the product that may cause electric shock. Contact your service representative if any of the product's internal components require maintenance, adjustment, or repair.

Do not disassemble or modify the product. Doing so may cause injury or malfunction.

When performing maintenance on the machine, always disconnect the power cord from the wall outlet.

Cleaning the Projection Window

When cleaning the projection window, make sure to do the following:

Use a commercially available blower or cloth for cleaning glass, cleaning paper, lens cleaner, etc.

The projection window surface scratches easily, so do not rub or tap it with a hard object.

Cleaning the Projector

When cleaning the projector, make sure to do the following:

Disconnect the power plug before cleaning.

Gently wipe any dirt from the projector using a soft cloth. Using a damp cloth may cause water to seep inside the projector and cause electric shock or malfunction.

Do not use benzene or paint thinners. Doing so may cause the projector to warp, discolor, or the paint to peel. Further, do not use cleaning cloths that contain chemicals.
