    Cleaning the lens
    Use a commercially available blower or lens
    cleaning paper (for glasses and camera lenses)
    for cleaning the lens. Do not use any liquid type
    cleaning agents, as they may wear off the coat-
    ing film on the surface of the lens.
    As the surface of the lens can easily get dam-
    aged, be sure not to scrape or hit the lens.
    Cleaning the exhaust and intake vents
    Use a vacuum cleaner to clean dust from the
    exhaust vent and the intake vent.
    Maintenance
    Cleaning the projector
    Be sure to unplug the power cord before clean-
    ing the projector.
    The cabinet as well as the operation panel is
    made of plastic. Avoid using benzene or thinner,
    as these can damage the finish on the cabinet.
    Do not use volatile agents such as insecticides
    on the projector.
    Do not attach rubber or plastic items on the pro-
    jector for long time.
        The effects of some of the agents in the plastic
    may cause damage to the quality or finish of the
    projector.
    Wipe off dirt gently with a soft flannel cloth.
    When the dirt is hard to remove, soak a cloth in a
    neutral detergent diluted with water, wring the
    cloth well and then wipe the projector.
    Strong cleaning detergents may discolor, warp
    or damage the coating on the projector.
    Make sure to test on a small, inconspicuous area
    on the projector before using.

    Maintenance Indicators
    The warning lights on the projector indicate problems inside the projector.
    If a problem occurs, either the temperature warning indicator or the lamp replacement indicator will
    illuminate red, and the power will turn off. After the power has been turned off, follow the proce-
    dures given below.

    About the temperature warning indicator
    If the temperature inside the pro-
    jector increases, due to blockage
    of the air vents, or the setting lo-
    cation, “
    ” will blink in the
    lower left corner of the picture. If
    the temperature keeps on rising,
    the lamp will turn off and the tem-
    perature warning indicator will
    blink, the cooling fan will run for
    further 90 seconds, then the power
    will be shut off. After “
    ” ap-
    pears, be sure to perform the fol-
    lowing measures.
    About the lamp
    replacement indicator
    The lamp life becomes 0%, when used
    for approximately 2,000 hours with “ON”
    in “Power Save” or when used for approxi-
    mately 1,500 hours with “OFF” in “Power
    Save” (see page 69).
    When the remaining lamp life becomes
    6% or less, “
    ” will be displayed on the
    screen in yellow. When the percentage
    becomes 0%, “
    ” will change to “”
    (red), the lamp will automatically turn off
    and then the projector as well. At this time,
    the lamp replacement indicator will illu-
    minate in red.
    If you try to turn on the projector a fourth
    time without replacing the lamp, the pro-
    jector will not turn on.

    Maintenance Indicators
    Info
    •If the temperature warning indicator illuminates, and the power turns off, follow the above possible solutions
    and then wait until the projector has cooled down completely before plugging in the power cord and  turning
    the power back on. (At least 5 minutes.)
    •If the power is turned off and then turned on again, as during a brief test, the lamp replacement indicator may
    be triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet
    and plug it back in again.
    •If you want to clean the air vents during projector operation, be sure to first press 
     and after the power has
    turned off and the cooling fan has stopped, then clean the vents.
    •Do not unplug the power cord after the power has been turned off and while the cooling fan is running. The
    cooling fan runs for about 90 seconds.

    Lamp
    It is recommended that the lamp (sold separately) be replaced when the remaining lamp life be-
    comes 6% or less, or when you notice a significant deterioration in the picture and color quality. The
    lamp life (percentage) can be checked with the on-screen display. See page 70.
    For lamp replacement, please consult your nearest Sharp Authorized Projector Dealer or Service
    Center.
    IMPORTANT NOTE TO U.S. CUSTOMERS:
    The lamp included with this projector is backed by a 90-day parts and labor limited warranty. All service
    of this projector under warranty, including lamp replacement, must be obtained through a Sharp Autho-
    rized Projector Dealer or Service Center. For the name of the nearest Sharp Authorized Projector Dealer
    or Service Center, please call toll-free: 1-888-GO-SHARP (1-888-467-4277).
    U.S.A. ONLY
    Caution Concerning the Lamp
    This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp
    failure can be attributed to numerous sources such as: excessive shock, improper cooling, surface
    scratches or deterioration of the lamp due to a lapse of usage time. The period of time up to failure
    largely varies depending on the individual lamp and/or the condition and the frequency of use. It is
    important to note that failure can often result in the bulb cracking.
    When the lamp replacement indicator and on-screen display icon are illuminated or flash, it is rec-
    ommended that the lamp be replaced with a new one immediately, even if the lamp appears to be
    operating normally.
    Should the lamp break, the glass particles may spread inside the lamp cage or gas contained in the
    lamp may be vented into the room from the exhaust vent. Because the gas in this lamp includes
    mercury, ventilate the room well if the lamp breaks and avoid all exposure to the released gas. In
    case of exposure to the gas, consult with a doctor as soon as possible.
    Should the lamp break, there is also a possibility that glass particles may spread inside of the
    projector. In such a case, it is recommended you contact your nearest Sharp Authorized Projector
    Dealer or Service Center to remove the damaged lamp and assure safe operation.
    Replacing the Lamp
    Caution
    •Do not remove the lamp unit immediately after operation of the projector. The lamp will be hot and touching
    it can lead to burn or injury.
    •Wait at least one hour after the power cord is disconnected to allow the surface of the lamp unit to fully cool
    before removing the lamp unit.
    If the new lamp does not light after replacement, take your projector to the nearest Sharp Autho-
    rized Projector Dealer or Service Center for repair. Purchase a replacement lamp unit of type BQC-
    XGC50X//1 from your nearest Sharp Authorized Projector Dealer or Service Center. Then carefully
    change the lamp by following the instructions described in this section. If you wish, you may have
    the lamp replaced at your nearest Sharp Authorized Projector Dealer or Service Center.
