Maintenance

Cleaning the projector

Unplug the power cord before cleaning the projector.

Avoid using benzene or thinner, as these can damage the finish on the cabinet and operation panel.

Do not use volatile agents such as insecticides on the projector.

Do not leave rubber or plastic objects in contact with the projector for long periods as they may damage the finish of the projector.

Wipe off dirt gently with a soft flannel cloth.

For hard-to-remove dirt, soak a cloth in a neutral detergent diluted with water, wring the cloth well and then wipe the projector.

Strong cleaning detergents may discolor, warp or damage the coating on the projector. Make sure to test on a small, inconspicuous area on the projector before using.
