Maintenance

Cleaning the projector

■Be sure to unplug the power cord before cleaning the projector.

■The cabinet as well as the operation panel is made of plastic. Avoid using benzene or thinner, as these can damage the finish on the cabinet.

■Do not use volatile agents such as insecticides on

the projector.

Do not attach rubber or plastic items to the projector for a long time.

The effects of some of the agents in the plastic may cause damage to the quality or finish of the projector.

Cleaning the lens

■Use a commercially available blower or lens cleaning paper (for glasses and camera lenses) for cleaning the lens. Do not use any liquid type cleaning agents, as they may wear off the coating film on the surface of the lens.

■As the surface of the lens can easily get damaged, be sure not to scrape or hit the lens.
