Give a frequent clean especially to the air filter. (The cleaning period is once per about 50 hours). 1) Unplug the power cord. 2) Take off the air filter cover. The filter is on the right side of the projector. Pull up the filter tabs. 3) Clean the air filter cover. Remove dust and stains with a vacuum cleaner. Cleaner’s nozzle 4) Attach the air filter cover. Notes • When the air filter is dusty, the ventilation is impaired. This causes the temperature inside the projector to rise, and may damage the unit. • Attach the air filter cover firmly after the cleaning. If it is not set correctly, the dusts will enter and they will be projected and overlapped on the picture. Use a blower or a lens cleaner to clean the lens. Never rub or tap the lens with a hard object as the lens surface is fragile. Cleaning the main unit • Pull out the power cord before cleaning. • Use a soft cloth to wipe off stains from the surface. • To remove difficult stains, use a soft cloth slightly moistened with a weak solution of synthetic detergent and water, and finish with a soft, dry cloth.
