You cannot clean any of the internal surfaces. · To minimize the risk of damaging or scratching the lens surface, blow dust particles off the lens with clean, dry, deionized air. · If this method does not work, use the following method: a. Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and forth across the lens. If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still dirty after washing it or the fabric is damaged, replace it. CAUTION: Cleaning requires special consideration: · Do not spray any type of fluid or cleaner directly on the lens surface. · Do not use fabric softener when washing a cleaning cloth or softener sheets when drying the cloth. Chemicals on the cloth might damage the surface of the lens. · Do not store a cleaning cloth in contact with the lens for a long time because doing so contaminates the lens with dye from the cloth. The cloth can be contaminated if left in the open air. Performing routine maintenance 43 Replacing the lamp module As the projector operates over time, the brightness of the projector lamp gradually decreases and the lamp becomes more susceptible to breakage. You can install a new lamp at any time to bring the projector up to factory-fresh brightness. We recommend replacing the lamp if a warning message is displayed. WARNING! Replacing the lamp module requires special consideration: · To reduce the risk of injury, be careful when removing the lamp module as broken glass might be present. For a ceiling installation, wear goggles and gloves when removing the lamp module. If the lamp is broken, contact HP about repairs that might be required due to glass fragments. · The lamp contains a small amount of mercury. If the lamp breaks, adequately ventilate the area where the breakage occurred.
