    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 45 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 61 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. When 
    you carry the projector yourself, please use the original box or provided soft carry case. 
    						
    							Maintenance 54
    Lamp information
    Getting to know the 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 Setting Lamp Mode as Economic below 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.
    To obtain the lamp hour information:
    1. Press MENU/EXIT and then press  /  until the SYSTEM SETUP: Advanced menu 
    is highlighted.
    2. Press   to highlight Lamp Settings and press Mode/enter. The Lamp Settings page 
    displays.
    4. You will see the Equivalent Lamp Hour information displaying on the menu.
    5. To leave the menu, press MENU/EXIT.
    You can also get the lamp hour information on the INFORMATION menu.
    Extending lamp life
    The projection lamp is a consumable item that normally can last up to 3000-4000 hours 
    with proper usage. To keep the lamp life as long as possible, you can do the following settings 
    via the OSD menu.
    • Setting Lamp Mode as Economic
    Using Economic mode reduces system noise and power consumption by 20%. If the 
    Economic mode is selected, the light output will be reduced and result in darker projected 
    pictures.
    Setting the projector in Economic mode also extends the lamp operation life. To set 
    Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp Mode 
    menu and press  / .
    • Setting Auto Power Off
    This function allows the projector to turn off automatically if no input source is detected 
    after a set period of time to prevent unnecessary waste of lamp life.
    To  s e t  Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and 
    press  / . The time period can be set from 5 to 30 minutes in 5-minute increments. If the 
    preset time lengths are not suitable for your presentation, select Disable. The projector will 
    not automatically shut down in a certain time period. 
    						
    							Maintenance 55
    Timing of replacing the lamp
    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 59 for details.
    The following Lamp warning displays will remind you to change the lamp.
    StatusMessage
    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 51), 
    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.
    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.

    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.
    2. Use a coin to turn the screw counterclockwise 
    until the lamp cover loosens. 
    3. 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. 
    						
    							Maintenance 57 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.
    9. Replace the lamp cover on the projector.
