APPENDIX AIR FILTER CARE AND CLEANING Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror.

Make sure that Air Filter is fully inserted. CAUTION Do not operate a projector with Air Filter removed. Dust may accumulate on LCD Panel and Projection Mirror degrading picture quality. Do not put small parts into Air Intake Vents. It may result in malfunction of a projector. AIR FILTER Pull up and remove. RECOMMENDATION We recommend avoiding dusty/smoky environments when operating a projector. Usage in these environments may cause poor image quality. When using under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside a projector. This condition may degrade quality of a projected image. When above symptoms are noticed, contact your authorized dealer or service station for proper cleaning. CLEANING PROJECTION LENS Follow these steps to clean Projection Lens: 1 Apply a non-abrasive camera lens cleaner to a soft, dry cleaning cloth. Avoid using an excessive amount of cleaner. Abrasive cleaners, solvents or other harsh chemicals might scratch a surface. 2 Lightly wipe a cleaning cloth over Projection Lens. 3 When a projector is not in use, replace Lens Cover. 43
