Maintenance Care of the projector Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens clean and clean or replace the air filter. Never remove any parts of the projector except the air filter. Contact your dealer or local authorized Customer Service Centre if the projector fails to operate as expected. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface. Before you attempt to clean the lens, turn the projector off, unplug the power cable, and leave it several minutes to cool completely. 1.Use the lens cleaning paper to remove dust. 2.If there is stubborn dirt or smudge marks, use a proper photographic lens brush or moisten a clean soft lens cloth with lens cleaner to gently wipe the lens surface. Warning: Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can damage the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution. Do not attempt to clean the lens whilst the projector is switched on or is still hot from previous use. 46
