    Compatible Video Formats
    The projector supports computer displays ranging from VGA 
    through UXGA. EPSON’s patented SizeWise
    ™ chip 
    automatically resizes images as needed to display in the 
    projector’s native format. The projector also supports the new 
    Digital Visual Interface (DVI) format, as well as NTSC, PAL, 
    SECAM, and HDTV international video standards.
    To project images output from a computer, the computer’s 
    video card must be set at a refresh rate (vertical frequency) 
    that’s compatible with the projector; see the following table 
    for compatible formats. Note that the frequencies of some 
    computers may not allow images to be displayed correctly; 
    see your computer’s documentation for details.

    Positioning the Projector
    The projector can be installed in three ways:
    ❏front projection
    Place the projector on a sturdy, level surface, making sure 
    there is plenty of space for ventilation around and under the 
    ❏overhead projection
    To project from overhead, select 
    Ceiling in the projector’s 
    Advanced menu. To mount the projector, use the special 
    attachments and adapters listed in “Optional Accessories” on 
    page 14.
    ❏rear-screen projection
    To project from behind a semi-transparent screen, select 
    Rear Proj. in the projector’s Advanced menu.
    When equipped with the standard lens, you can place the 
    projector anywhere from 21 inches to 48 feet from the screen. 
    Image size varies with projection distance, as shown below; for 
    more information, see page 5.
    Be sure to center the projector in front of the screen (not off to 
    one side at an angle), or your image won’t be square.
    Adjusting the Height of the Image
    You won’t need to tilt the projector upward as long as you 
    position it so that its lens is at least as high as the bottom of 
    the screen, but no higher than the middle of the screen, as 
    shown. This delivers the best-looking picture.Adjust the height of the image using the lens shift knob, as 
    shown below. If the knob is recessed, press and release it so 
    that it extends; then turn it clockwise or counterclockwise to 
    move the image up or down. When you’re finished, press the 
    knob back in.
    If the image still isn’t high enough, you can raise it further 
    using the projector’s feet. Pull up on the blue foot release 
    levers to release the feet.
    Once the image is positioned where you want it, release the 
    levers to lock the feet in position. You can fine-tune the height 
    of the projector by turning the feet.
    If the image is no longer square after raising it, see the 
    following section.
    Correcting Keystone Distortion
    If the projected image isn’t square or 
    has “keystone” shape, press the 
    Keystone button on top of the 
    projector to correct it. Press on the 
    right + or left – side of the 
    button until the image looks correct.
    After correction, your image will be slightly smaller.
    Note: You can also correct the keystone shape using the projector’s 
    Setting menu.

    you access the projector’s features from anywhere in the 
    room—up to 32 feet away. You can point the remote either at 
    the front or back of the projector or at the screen.
    In addition to the functions described on the next page, you 
    can also use the remote control as a wireless mouse in the 
    following situations:
    ❏❏ ❏when using EasyMP.net
    The remote control lets you select the image you want to 
    view, click through your PowerPoint slides, and draw on the 
    screen to highlight your presentation. 
    ❏❏ ❏when presenting from a computer
    If you’re presenting from a laptop instead of using 
    EasyMP.net, you can use the remote control’s built-in 
    pointer and highlighting features. These let you annotate 
    your presentation on-screen. 
    You can also use the remote control in place of your 
    computer’s mouse. This gives you more flexibility when 
    delivering PowerPoint and other slideshow-style 
    presentations, since you won’t need to stand next to your 
    computer to change slides. To use the remote control in this 
    way, you have to connect the projector’s mouse cable 
    between your computer and the projector. 
    ❏❏ ❏when accessing the projector’s help and menu functions
    The remote control lets you access and use the projector’s 
    help system. It also lets you navigate the menu system to 
    fine-tune various projector features. 
    Note: If the remote control isn’t working, make sure the on/off 
    switch on its side is turned on and fresh batteries are installed. 
    The remote control also may not work properly if a strong light 
    source or radiant heater is present. See the next page for information on using the remote control

    Using the Control Panel 
    The following table summarizes the functions on the control 
    Cleaning the Lens 
    Warning: Before you clean any part of the projector, turn off the 
    projector and unplug the power cord. Never open any cover on the 
    projector, except the lamp and filter covers. Dangerous electrical 
    voltages in the projector can injure you severely. Do not try to 
    service this product yourself, except as specifically explained below. 
    Refer all other servicing to qualified service personnel.
    Clean the lens whenever you notice dirt or dust on the surface.
    ❏Lightly wipe the lens surface with a soft, dry, lint-free cloth.
    ❏To remove dirt or smears on the lens, moisten a soft cloth 
    with an alcohol-based cleaner and gently wipe the lens 
    Cleaning the Projector Case 
    Before you clean the projector case, turn off the projector and 
    unplug the power cord. 
    ❏To remove dirt or dust, wipe the case with a soft, dry, lint-
    free cloth. 
    ❏To remove stubborn dirt or stains, moisten a soft cloth with 
    water and a neutral detergent. Then wipe the case. 
    ❏Do not use alcohol, benzene, thinner, or other chemical 
    detergents. These can cause the case to warp.
    Cleaning the Air Filter
    Clean the air filter at the bottom of the projector after every 
    100 hours of use. If it is not cleaned periodically, it can 
    become clogged with dust, preventing proper ventilation. This 
    can cause overheating and damage the projector.
    Follow these steps:
    1. Turn off the projector and unplug the power cable.
    2. Turn the projector on its side so that the handle is on top 
    and you can access the filter easily.
    Note: Standing the projector with the handle at the top keeps 
    dust from getting inside the projector housing.
