  • Page 12: Lamp Handling Precautions

    Lamp replacement LAMP HANDLING PRECAUTIONS This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard. ● Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp.

  • Page 13: Maintenance And Cleaning

    ■ Maintenance and Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray.

  • Page 14: Air Filter Care And Cleaning

    Maintenance and Cleaning AIR FILTER CARE AND CLEANING Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror. Should Air Filter become clogged with dust particles, it will reduce Cooling Fans' effectiveness and may result in internal heat build up and adversely affect life of a projector.
