    About color temperature
    There are different kinds of white color. Color temperature is a way to show the differences in white. White of which 
    temperature is low appears reddish. When the color temperature rises, white appears bluish. For example, you can 
    change the color temperature using the following procedures.
    To rise the color temperature: Increase the CONTRAST B (blue) and decrease the CONTRAST R (red).
    To reduce the color temperature: Decrease the CONTRAST B (blue) and increase the CONTRAST R (red).
    If you set all of CONTRAST R, G, and B to negative values, the original \
    brightness of the image can’t be 
    •	
    obtained even when you maximize CONTRAST in the IMAGE menu.

    This projector is equipped with a lamp to project images. This lamp is a consumable. It may burn out or its brightness 
    may decrease during use. In such cases, replace the lamp with a new one as soon as possible. Be sure to replace the 
    lamp with a new lamp sold separately that is exclusive to this projector. Contact your dealer for purchase of the lamp.
    Spare lampVLT-HC6800LP
    Warning: Be careful not to drop the lamp fixing screws inside of the projector. Don’t put a metal piece or flammable object 
    •	
    into the projector. Using the projector with any foreign object present inside may result in electric shock or fire. 
    When you can’t remove the foreign object from the inside, contact your dealer for removal.
    Be sure to install the lamp securely. When the lamp isn’t installed properly, it won’t illuminate. Improper installation 
    •	
    may also result in fire.
    Don’t shake the removed lamp or don’t lift it above your face. Your eyes may be injured by flying or falling glass 
    •	
    fragments.
    Don’t replace the lamp immediately after use because the lamp cover will be ver\
    y hot. You may get burned. Turn 
    •	
    off the power using the POWER button. After the lamp goes out, wait about \
    two minutes until the intake and 
    exhaust fans for cooling the lamp stop rotating. Then turn off the main power switch, unplug the power cord, and 
    wait at least 1 hour to allow the lamp to cool down enough to the touch.\
    Do not touch the lamp directly. It may break and cause injury or burn.
    •	
    Interval of lamp replacement
    The recommended interval of lamp replacement is about 4000 hours*1*2 of consecutive use. Such interval differs 
    depending on the operating environment and may be shorter than 4000 hours*1*2. Decrease in luminescence and/or 
    color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 3000 hours*1, 
    the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator 
    will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp 
    is turned on. When the lamp has been used for about 3800 hours*
    1, the replacement message (LAMP EXCHANGE) 
    will appear on the screen for one minute every 20 hours*1 thereafter. When the lamp operation time exceeds 4000 
    hours*1*2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp 
    operation time is reset.
    *1:  Duration when LAMP MODE of the INSTALLATION menu is set to LOW. When it is set to STANDARD, this duration will be 
    shorted.
    *2:  When LAMP MODE is set to STANDARD, this duration will be shorted to 2000 hours.
    Caution: Don’t remove the lamp for any purpose other than replacement. Unnecessary removal of the lamp may result in a 
    •	
    breakdown.
    This projector uses a high-pressure mercury lamp as the light source. The high-pressure mercury lamp may 
    •	
    explode or fail to illuminate permanently because of an impact, scratch,\
     or deterioration through use. The period 
    of time until explosion or permanent failure to illuminate varies considerably from lamp to lamp, depending on 
    operation conditions. Therefore, the lamp may explode soon after the start of use.
    The possibility of explosion of the lamp increases if you use it beyond its replacement period. When the instruction 
    •	
    of lamp replacement appears, replace it with a new one immediately even if the lamp is still lighting \
    normally.
    When the high-pressure mercury lamp explodes, glass fragments will scatter inside or outside the l\
    amp box and 
    •	
    the gas charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains 
    mercury. Be careful not to breathe it or avoid it from entering your eye or mouth. If you should breathe it or if it 
    should enter your eye or mouth, see a doctor immediately.
    In the event that the high-pressure mercury lamp exploded, glass fragments may have been scattered inside the 
    •	
    projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace 
    the lamp by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments.
    When removing the lamp from the ceiling-mounted projector, use the lamp replacement tray packed with the 
    •	
    projector or option lamp to prevent glass fragments from scattering.
    Be sure to use the lamp exclusive to this projector, VLT-HC6800LP. Use of other lamps may cause a failure of the 
    •	
    projector.

    Warning:Never use flammable air duster or other materials when cleaning the ai\
    r-filter. Flammable substances may ignite 
    •	
    causing fire or breakdown when the lamp is illuminated.
    Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body 
    •	
    and lens. Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.
    Caution:
    Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on 
    the projector.
    Cleaning of the air-filter
    Clean the air-filter frequently (about once a month). If the air-filter or ventilation grilles become clogged with dirt or 
    dust, the temperature inside the projector may rise and cause troubles, such as damage to the inside parts and 
    shortening the life of the panels. When the temperature inside the projector rises, the STATUS 
    •	
    indicator will blink orange and the lamp will be turned off.
    Loosen two screws that are fixing the right side panel using a 
    1. 
    Phillips screwdriver (+) and remove the panel from the projector. 
    Remove the filter from the right side panel.
    2. 
    (1)  Remove the holder by pushing the tab of the holder on the air-filter in the direction of the arrow.
    (2)  Remove the air-filter (white), spacer, and air-filter (gray).
    Clean dirt and dust adhering to the air-filter using a vacuum.
    3. 
    For the air-filter (white) 
    •	
    If stubborn stains persist, wash the air-filter with water 
    and dry well in the shade.
    For the air-filter (gray) 
    •	
    If stubborn stains persist, wash the air-filter with diluted 
    detergent, rinse with water, and dry well.
    Attach the filter to the right side panel.
    4. 
    (1)  Attach the air-filter (gray), spacer, and air-filter (white) to the side panel, aligning their notches with that of the side panel. 
    (2)  Insert the right tab of the holder to the side panel and push the  left tab in the direction of the arrow to attach the side panel.
    Attach the right side panel to the projector and fix it with two 
    5. 
    screws. 
    Important: If the air-filter is damaged or becomes extremely dirty, change it 
    •	
    with a new air-filter. Contact your dealer for a new air-filter.
    Use the dedicated air-filter only.
    •	
    Caution:
    Be sure to use the projector with an air-filter. If not, dust may get inside the projector causing fire and failure.
    Cleaning of the projector and the ventilation slots
    Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft 
    cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.
    To protect the surface of the projector from fading or deteriorating:
    Do not spray insecticide on or inside the projector.
    •	
    Do not use benzine or thinner to clean it.
    •	
    Do not let rubber or plastic materials contact with projector.
    •	
    Cleaning of the lens
    Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens clean\
    ing fluid. The lens surface is 
    fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens w\
    ith your fingers.
