  • Page 5: Circuit Protections

    ■ Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. ● Fuse A fuse(F601) is located inside of the projector. When the POWER indicator is not lightning, the fuse may be opened.

  • Page 6: Lamp Cover Switch

    ● Lamp cover switch LAMP COVER The lamp cover switch (SW8803) cuts off the drive sig- nal to the lamp circuit when the lamp cover is removed or not closed completely. After opening the lamp cover for replacing the lamp unit, place the lamp cover correctly otherwise the pro- jector can not turn on.

  • Page 7: 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 8: Cleaning The Rgb Panels

    Cleaning the RGB panels Blemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of the screen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality.

  • Page 9: Bottom View

    Cleaning Clean by using the Cleaning function in the Setting Menu Turn the projector on and press the MENU button to display the On-Screen Menu. Select the Setting Menu with the Point buttons. Press the Point or OK buttons to access the sub-menu items.
  • Page 10 Cleaning the Air Filters The air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in a buildup of internal heat and adversely affect the life of the projector.
  • Page 11 Cleaning the Projection Lens Unplug the AC power cord before cleaning. Gently wipe the projection lens with a cleaning cloth that contains a small amount of non-abrasive camera lens cleaner, or use a lens cleaning paper or a commercially available air blower to clean the lens.
