    Maintenance
    Care of the projector
    Your projector needs little maintenance. The only thing you need to do on a regular basis is 
    to keep the lens clean.
    Never remove any parts of the projector except the lamp. Contact your dealer if other parts 
    need replacing.
    Cleaning the lens
    Clean the lens whenever you notice dirt or dust on the surface. 
    • Use a canister of compressed air to remove dust. 
    • If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner 
    and gently wipe the lens surface.
    Never rub the lens with abrasive materials.
    Cleaning the projector case
    Before you clean the case, turn the projector off using the proper shutdown procedure as 
    described in Shutting down the projector on page 40 and unplug the power cord.
    • To remove dirt or dust, wipe the case with a soft, lint-free cloth.
    • To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH 
    detergent. Then wipe the case.
    Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the 
    case.
    Storing the projector
    If you need to store the projector for an extended time, please follow the instructions below:
    • Make sure the temperature and humidity of the storage area are within the 
    recommended range for the projector. Please refer to Specifications on page 59 or 
    consult your dealer about the range.
    • Retract the adjuster feet.
    • Remove the batteries from the remote control.
    • Pack the projector in its original packing or equivalent.
    Transporting the projector
    It is recommended that you ship the projector with its original packing or equivalent.

    Lamp information
    Calculation of lamp hour
    When the projector is in operation, the duration (in hours) of lamp usage is automatically 
    calculated by the built-in timer. The method of calculating the equivalent lamp hour is as 
    follows:
    Total (equivalent) lamp hour
    = 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
    See Lamp mode (Normal) on page 49 for more information on Economic mode.
    The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using 
    the projector in Economic mode helps to extend the lamp hour by 1/3.
    Warning message
    When the Lamp indicator lights up red or a message appears suggesting it is time to replace 
    the lamp, please install a new lamp or consult your dealer. An old lamp may cause a 
    malfunction in the projector and in some instances the lamp may explode.
    The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
    hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator 
    still lights up after turning the power back on, please contact your dealer. See Indicators on 
    page 56 for details.
    The following Lamp warning displays will remind you to change the lamp.
    MessageStatus
    The lamp has been in operation for 3000 hours. 
    Install a new lamp for optimal performance. If the 
    projector is normally run with Economic Mode 
    selected (See Lamp mode (Normal) on page 49), 
    you may continue to operate the projector until the 
    3950 hour lamp warning appears. 
    The lamp has been in operation for 3950 hours. A 
    new lamp should be fitted to avoid the 
    inconvenience when the projector runs out of lamp 
    time.

    							Maintenance 53
    Replacing the lamp
    • To reduce the risk of electrical shock, always turn the projector off and disconnect the 
    power cord before changing the lamp.   
    • To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes 
    before replacing the lamp.
    • To reduce the risk of injuries to fingers and damage to internal components, use caution 
    when removing lamp glass that has shattered into sharp pieces.
    • To reduce the risk of injuries to fingers and/or compromising image quality by touching 
    the lens, do not touch the empty lamp compartment when the lamp is removed.
    • This lamp contains mercury. Consult your local hazardous waste regulations to dispose of 
    this lamp in a proper manner.
    • To assure optimal performance from the projector, it is recommended that you purchase a 
    BenQ projector lamp for lamp replacement.
    • If lamp replacement is performed while the projector is suspended upside-down from the 
    ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury 
    or damage to the human eyes caused by fractured lamp.
    1. Turn the power off and disconnect the projector from the wall socket. If the lamp is 
    hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled. The lamp has been in operation for 4000 hours. 
    It is strongly recommended that you replace the 
    lamp at this age. The lamp is a consumable item. 
    The lamp brightness diminishes with use. This is 
    normal lamp behavior. You can replace the lamp 
    whenever you notice that the brightness level has 
    significantly diminished. If the lamp is not 
    replaced beforehand, it must be replaced after 3000 
    hours usage.
    The lamp MUST be replaced before the projector 
    will operate normally.
    OK
    Replace Lamp Now 
    Lamp > 4000 Hours

    Notice
    2. Turn the projector over. Then use a coin to 
    turn the screw counterclockwise until the lamp 
    cover loosens.  
    						
    							Maintenance 543. Remove the lamp cover from the projector.
    • Do not turn the power on with the lamp cover 
    removed.
    • Do not insert your fingers between the lamp and 
    the projector. The sharp edges inside the 
    projector may cause injuries.
    4. Loosen the screw that secures the lamp.
    5. Lift the handle so that it stands up. Use the 
    handle to slowly pull the lamp out of the 
    projector.
    • Pulling it too quickly may cause the lamp to break 
    and scatter broken glass in the projector.
    • Do not place the lamp in locations where water 
    might splash on it, children can reach it, or near 
    flammable materials.
    • Do not insert your hands into the projector after 
    the lamp is removed. If you touch the optical 
    components inside, it could cause color 
    unevenness and distortion of the projected 
    images.
    6. As shown in the figure, lower the new lamp 
    first into the connector on the projector and 
    align the two holes on the projector.
    7. Tighten the screw that secures the lamp.
    • Loose screw may cause a bad connection, which 
    could result in malfunction.
    • Do not over tighten the screw.
    8. Ensure the handle is fully laid flat and locked in 
    place. 
    						
    							Maintenance 55 11. Restart the projector.
    Do not turn the power on with the lamp cover removed. 
    12. After the startup logo, open the On-Screen 
    Display (OSD) menu. Go to the SYSTEM 
    SETUP: Advanced > Lamp Settings menu. 
    Press ENTER. The Lamp Settings page 
    displays. Highlight Reset Lamp Timer. A 
    warning message displays asking if you want 
    to reset the lamp timer. Highlight Reset and 
    press ENTER. The lamp time will be reset to 0.
    Do not reset if the lamp is not new or replaced as this could cause damage. 
    Temperature information
    When the Temperature warning light is on, it is warning you of the following possible 
    problems:
    1. The internal temperature is too high.
    2. The fans are not working.
    Turn the projector off and contact qualified service personnel for further help. For more 
    detailed information, please refer to Indicators on page 56. 9. Replace the lamp cover on the projector.
    10. Use a coin to turn the screw clockwise until the 
    lamp cover is secured.
