    FUNCTION 
    (default 
    setting / value)
    DESCRIPTION
    Auto Resize 
    (on)
    Automatically resizes the input signal pixel resolution to the native resolution 
    of the projector.
    On: The pixel resolution of the input signal is converted to the native 
    resolution of the projector (1024 x 768). For input signals with lower 
    resolutions, gaps in the pixels are automatically interpolated into the image 
    before being projected. This may distort the image clarity.
    Off: The image is projected as its original resolution, with no pixel conversion. 
    For input signals with lower resolutions, the projected image will display 
    smaller than if resized to full screen. You could adjust the zoom setting or move 
    the projector towards the screen to increase the image size if necessary. You 
    may also need to refocus the projector after making these adjustments.

    overall system cooling and performance.
    If you use this projector under other extreme conditions excluding the 
    above, it may display auto shut-down symptoms, which is designed to 
    protect your projector from over-heating. In cases like this, you should 
    switch to High Altitude mode to solve these symptoms. However, this is 
    not to state that this projector can operate under any and all harsh or 
    extreme conditions.

    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 Shutdown on page 30 and unplug the power cord.
    • To remove dirt or dust, wipe the case with the supplied cleaning 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 51 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.
    Cleaning and replacing the dust filter
    It is necessary to clean the dust filter periodically. If the filter is not cleaned, it can become 
    clogged with dust and prevent proper ventilation. This can cause overheating and a 
    malfunction of the projector.

    							Maintenance 41 A warning message like the one pictured to 
    the right will be displayed for 10 seconds 
    every 500 hours to remind you to clean the 
    filter. To leave the message, press the Exit 
    button on the projector or remote control.
    To clean the filter:
    1. Turn the projector off and wait until the fans stop running.
    2. Disconnect the projector from any cables.
    3. Locate the filter case on the back of the 
    projector.
    4. Release the filter case from the projector by 
    pressing the filter case into the slot slightly. The filter case 
    springs out of the slot. 
    5. Pull out the filter case.
    6. Use a small vacuum cleaner designed for 
    computers and other office equipment to clean the 
    filter sponge. Or use a soft brush (such as a clean 
    artist’s paintbrush) to gently sweep the dust on the 
    filter away.
    If the dirt is difficult to remove or the filter is 
    broken, replace it with the supplied spare filter 
    sponge. See How to replace the filter sponge: 
    below.
    Please check if the filter is clean
    Clean the filter or replace with a new one
    Press “Exit” to leave

    							Maintenance 427. Refit the filter case by aligning and inserting it into 
    the projector slot.
    8. Press the case back until it clicks into place.
    9. Turn the projector back on.
    If the case is not correctly seated in place, the 
    projector will display an on-screen message as 
    pictured to the right every three minutes.
    The message will display 3 times for a 10-second 
    duration each, if no further action is taken.
    Then a second message as pictured below displays to warn of shutdown in 1 minute.
    You can re-attach the case correctly anytime before the projector shuts down. (That 
    means you have 10-11 minutes to get the re-attachment done from the time the first 
    warning message was displayed.) The projector will return to normal operation.
    How to replace the filter sponge:
    If you find the dirt is hard to remove from the filter sponge or the sponge is broken, replace 
    it. 
    1. Carefully peel the filter sponge away from the filter case. 
    See that there are small plastic pins along the edges to 
    position and retain the sponge into place. Lift the sponge 
    up off these pins taking care to prevent them from 
    breaking off.
    2. Attach the supplied new filter sponge to the filter case. 
    Make sure that the tiny holes securely fit onto the case’s 
    pins.
    Please check

    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 = 3/4 (hours used in Economic mode) + 1 (hours used in 
    normal mode)
    See Economic Mode (off ) on page 38 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.
    For more detailed information on projector warnings, please refer to Indicators on page 
    47.
    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.
    The following Lamp warning displays will remind you to change the lamp.
    MessageStatus
    The lamp has been in operation for 2800 hours. 
    Install a new lamp for optimal performance. If the 
    projector is normally run with Economic Mode 
    selected (See Economic Mode (off ) on page 38), 
    you may continue to operate the projector until the 
    2950 hour lamp warning appears.
    The lamp has been in operation for 2950 hours. A 
    new lamp should be fitted to avoid the 
    inconvenience of shutdown when the projector runs 
    out of lamp time.
    The lamp has been in operation for over 3000 hours. 
    This message will flash in the center of the screen for 
    about 30 seconds together with the Lamp indicator 
    lighting up red for 40 seconds. 
    It is strongly recommended that you replace the 
    lamp at this age. The lamp is a consumable item. 
    With the usage time increase, the lamp brightness 
    diminished gradually. 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.
