You can clean the front lens of the projector using the following recommendations. · To minimize the risk of damaging or scratching the lens surface, blow dust particles off the lens with clean, dry, deionized air. 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. · 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 41 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. 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. If the lamp is broken, contact HP about repairs that might be required due to glass fragments. · This digital projector lamp contains a small amount of mercury. If the lamp breaks, adequately ventilate the area where the breakage occurred, discard any nearby food and drink, and thoroughly clean the table surface around the projector. Disposal of this lamp may be regulated due to environmental considerations. For disposal or recycling information, please contact your local authorities or the Electronic Industries Alliance (www. eiae. org). You can find safety information about the lamp at: www. hp. com/hpinfo/globalcitizenship/environment/productdata · Because the lamp assembly operates at a very high temperature, wait 30 minutes before removing the lamp module.
