Maintenance Cleaning the projector ■ Ensure the power cord is unplugged 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 long periods. 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 careful not to scrape or hit the lens. PaCpleeraning Mild detergent diluted with water Cleaning the exhaust and intake vents ■ Use a vacuum cleaner to clean dust from the exhaust vent and the intake vent. Appendix Mild detergent Wax Thinner ■ Wipe off dirt gently with a soft flannel cloth. ■ When the dirt is hard to remove, soak a cloth in a mild 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 use.
