    Compatible Video Formats
    You can use any of the following video sources: VCR, DVD 
    player, camcorder, digital camera, gaming console, or laser 
    disc player. The projector supports composite video, S-video, 
    component video, and RGB video, and it automatically senses 
    the video format (HDTV, NTSC, PAL, or SECAM). 
    The projector supports these international video standards: 
    Compatible Computer Display Formats
    You can connect the projector to a wide range of computers, 
    including PCs and laptops, Apple Macintosh,
    ®  Power 
    Macintosh® series (including G3 and G4 systems), 
    PowerBook®  computers, many iMac® and iBook® series 
    systems, and high-end workstations such as the Sun® 
    SPARCstation.™ 
    Although images are displayed at the projector’s native 
    resolution of 1024 × 768 pixels, EPSON’s patented 
    SizeWise
    ™ chip supports computer display formats ranging 
    from VGA through UXGA.To project images output from a computer, the computer’s 
    external monitor signal must be set at a refresh rate (vertical 
    frequency) that’s compatible with the projector; see the 
    following table for compatible formats. For best results, the 
    computer’s resolution should be set to match the projector’s 
    native resolution (1024 
    × 768). 
    * The image is resized using EPSON’s SizeWise Technology.

    Positioning the Projector
    Follow these guidelines:
    ❏Place the projector on a sturdy, level surface, between 
    2.6 and 36 feet from the screen. Image size generally 
    increases with distance, but may vary depending on the 
    position of the zoom ring and other settings.
    ❏Place it within 10 feet of an electrical outlet or extension 
    cord and 5 feet of your computer or video source.
    ❏Allow space for ventilation around and under the projector.
    ❏To avoid a keystone shaped image (an image that is wider 
    on one side), place the projector directly in front of the 
    center of the screen, facing the screen squarely. 
    ❏If possible, place the projector level with the bottom of the 
    screen. 
    If you place the projector too far below the screen, you may 
    have to tilt it up by extending the front adjustable foot (see 
    page 7). This causes the projected image to lose its shape, but 
    the projector automatically compensates. If the image is still 
    not square, adjust it manually by pressing the 
    Keystone 
    buttons (see page 7) or using Quick Corner (see page 8).
    If you place the projector higher than the bottom of the 
    screen, the image will be square, but it won’t fill the screen.
    Calculating Image Size and Projection 
    Distance
    Use the formulas below to find out how large the image will 
    be when you know the distance from projector to screen, or to 
    find out how far from the screen to place the projector if you 
    want an image of a certain size. Since you can change the 
    image size by rotating the zoom ring, formulas are given for 
    calculating both minimum and maximum sizes.
    Note: Formulas given here apply only when the image is not 
    tilted. If you tilt the image up by extending the projector’s foot or 
    using electronic keystone correction, your image size may vary.
    Standard Lens 
    To determine the diagonal size of an image (in inches) when 
    you know the projection distance:
    ❏Maximum diagonal size =
    ((2.54
     × projection distance) / 100) × 36) + 2.13
    ❏Minimum diagonal size = 
    ((2.54
     × projection distance) / 100) × 26.84) + 1.29
    To determine the projection distance (in inches) when you 
    know the diagonal size of the screen image:
    ❏Maximum projection distance = 
    ((diagonal size – 1.29) / 26.84) 
    × 100 / 2.54
    ❏Minimum projection distance = 
    ((diagonal size – 2.13) / 36) 
    × 100 / 2.54
    Middle Throw Lens (V12H004M03)
    To determine the diagonal size of an image (in inches) when 
    you know the projection distance:
    ❏Maximum diagonal size = 
    ((2.54
     × projection distance ) / 100) × 27.42) + 1.49
    Minimum diagonal size = 
    ((2.54
     × projection distance) / 100) × 20.48) + 1.1
    To determine the projection distance (in inches) when you 
    know the diagonal size of the screen image:
    ❏Maximum projection distance = 
    ((diagonal size – 1.1) / 20.48) 
    × 100 / 2.54
    ❏Minimum projection distance = 
    ((diagonal size – 1.49) / 27.42) 
    × 100 / 2.54
    Long Throw Zoom Lens (V12H004L05)
    To determine the diagonal size of an image (in inches) when 
    you know the projection distance:
    ❏Maximum diagonal size = 
    ((2.54
     × projection distance) / 100) × 20.4) + 1.93
    ❏Minimum diagonal size = 
    ((2.54
     × projection distance) / 100) × 15.23) + 1.45
    To determine the projection distance (in inches) when you 
    know the diagonal size of the screen image:
    ❏Maximum projection distance = 
    ((diagonal size – 1.45) / 15.23) 
    × 100 / 2.54

    Connecting the Projector
    You can connect the projector to three computer sources or 
    four video sources—up to a total of four sources. You can 
    include an independent sound channel for each source. (See 
    the User’s Guide for complete setup instructions.) Using 
    EasyMP,
    ® you can also connect over a wireless network, or 
    view images on a memory card or digital camera.
    Note: The preview feature lets you see all the sources at a glance, 
    so you can easily switch among them. See page 5.
    Types of Connections
    The following connections are possible, depending on the 
    signal your equipment generates and its available output ports.
    Note that the projector’s 
    Computer and BNC ports accept a 
    variety of input signals. If you’re connecting to one of these 
    ports, you’ll need to make sure that the correct input signal 
    setting is selected, or your image won’t display properly. 
    To change the input signal setting, do the following:
    1. After turning on the projector, press the 
    Menu button. The 
    menu screen appears.
    2. Select the 
    Setting menu.
    3. Change the 
    Computer Input or BNC Input setting as 
    needed to match the signal generated by your computer or 
    video equipment. (See the User’s Guide for more 
    information.)Playing Sound Through the Projector
    You can play sound through the projector’s speaker system or 
    you can attach an external speaker system.
    To play sound through the projector, use one of the following 
    cables that came with your projector: 
    ❏If you have a computer or video equipment connected to 
    the 
    Computer or DVI port, use the stereo mini-jack cable. 
    Connect one end to the correct audio port (see below), and 
    the other end to the audio-output connector on your 
    equipment.
    ❏If you have a computer or video equipment connected to 
    the 
    BNC ports, or to the Video or S-Video port, use the 
    the RCA-style audio cable. Connect one end to the jack 
    corresponding to the connected port, and the other end to 
    the audio-output connector on your equipment.
    To connect external speakers, use the 
    Audio Out port on the 
    back of the projector. You may be able to use a commercially 
    available audio cable with a stereo mini-jack connector on one 
    end and pin jacks on the other, or you may have to purchase a 
    special cable or use an adapter, depending on your stereo 
    system. See the User’s Guide for more information.
    Using the Remote Control as a Wireless 
    Mouse
    If you’ve connected a computer to the projector, you can 
    use the projector’s remote control as a wireless mouse by 
    connecting the USB cable that came with the projector to 
    the projector’s 
    Type B USB port. The wireless mouse function 
    is supported on systems with a USB port running Windows® 
    XP, 98, 2000, or Me, or Macintosh OS 8.6 to OS X 10.2. See 
    the User’s Guide for more information.

    Starting Up the Projector
    If you turn on your computer or video equipment before the 
    projector, the projector automatically selects the connected 
    source. If you turn on the projector first or you have multiple 
    sources connected, you may have to switch to the desired 
    source manually (see “Selecting the Image Source” on page 5).
    Turning On the Projector
    1. Remove the lens cap.
    2. Plug in the projector. 
    3. Wait a few seconds until the projector’s P
     power light stops 
    flashing and turns orange. 
    4. Press the red P
     Power button on top of the projector or on 
    the remote control.
    Note: If you’re using the remote 
    control, make sure batteries are 
    installed and the power switch on 
    the side of the remote control is 
    turned on. 
    The projector’s P
     power light flashes green as it warms up, 
    and an image begins to appear after about 30 seconds. 
    When the P
     power light stops flashing and remains green, 
    the projector is ready for use. 
    Wa r n i n g :  Never look into the lens when the lamp is on. This 
    can damage your eyes.
    5. If you’ve connected a Windows-based computer to the 
    projector, you may see a New Hardware Wizard saying 
    your computer has found a plug-and-play monitor; if so, 
    click 
    Cancel.
    Selecting the Image Source
    If multiple devices are connected to the projector, you can use 
    the 
    Source buttons on the projector or the remote control to 
    switch from one source to another:❏The projector’s control panel has two 
    Source buttons. 
    Use the 
    Computer/DVI button to 
    switch between EasyMP,™ and 
    between equipment connected to the 
    Computer and DVIports.
    Use the 
    Video/BNC button to switch 
    between equipment connected to the 
    Video, S-Video, and BNC ports. 
    ❏The remote control has six 
    Source 
    buttons.  Use them to switch 
    between equipment connected to 
    the port identified on each button, 
    or select 
    EasyMP to project 
    wirelessly or from a memory card.
    You can preview all sources to help 
    you select the desired source, as described below.
    The 
    Computer and BNC ports can be set up to use different 
    input signals, so if you have equipment connected to one of 
    these ports, be sure to select the correct signal to match the 
    equipment you’re using. You can change the input signal 
    settings using the projector’s menu system as described in 
    “Types of Connections” on page 4.
    Previewing Image Sources
    Use the preview function to select the image source when you 
    have connected multiple sources to the projector. 
    1. Press the 
    Preview button on the 
    remote control.
    You see the currently selected 
    source displayed on the screen, as 
    shown below. Other sources 
    (including the currently selected source) appear in smaller 
    preview windows on the right and bottom of the screen.
    .
    If no equipment is connected to a port, or if there is no 
    incoming signal, the preview window for that source 
    appears blank. 
    Note: Movies are displayed as still images on the preview 
    screen.

    Adjusting the Image
    Once you see your image, you may need to make certain 
    adjustments. 
    Focusing and Zooming Your Image
    Use the focus ring on the projector to sharpen the image.
    Use the zoom ring on the projector to reduce or enlarge the 
    image. Move the tab toward the 
    W to make it bigger, or 
    toward the 
    T to make it smaller.
    If the image still isn’t large enough, you may need to move the 
    projector farther away from the screen. You can also use the 
    E-Zoom buttons on the remote control to zoom in on a 
    portion of the image.
    Adjusting the Height of Your Image
    If the image is too low on the screen, you can raise it by 
    adjusting the front foot:
    1. Stand behind the projector. Press the blue foot release lever 
    up and lift the front of the projector. 
    2. Once the image is positioned where you want it, release the 
    lever to lock the foot in position.
    3. If necessary, you can fine-
    tune the height by turning 
    the projector’s rear feet. Raising the projector causes the image to distort or 
    “keystone,” but you can manually correct the shape as 
    described in the next section.
    Adjusting the Image Shape
    In most cases, you can maintain a rectangular image by 
    placing the projector directly in front of the center of the 
    screen with the base of the lens level with the bottom of the 
    screen. 
    Even if the projector is slightly tilted (within a range of 40° up 
    or down), the projector’s automatic keystone correction 
    function detects and corrects vertical keystone distortion.
    It takes about one second after projection starts for the image 
    to be corrected. During this time, a vertical keystone 
    correction gauge appears on the screen. 
    If your image is still distorted, you can correct it using either 
    of these methods: 
    ❏If the image has two parallel 
    sides but is wider on the top, 
    bottom, left, or right, you 
    can correct it using the 
    Keystone keys on the 
    projector’s control panel or 
    the Keystone menu (see 
    “Using Keystone 
    Correction” on page 7).
    ❏If the image has no parallel 
    sides, you can adjust its 
    shape using Quick Corner
    ™ 
    (see page 8). 
    You cannot use both keystone 
    correction and Quick Corner at the same time. 
    Using Keystone Correction
    To adjust your image when it is wider on one side, do one of 
    the following:
    ❏Look at the shapes of the icons on the 
    projector’s four 
    Keystone buttons. 
    Press the button whose icon is the 
    opposite shape of your screen image. 
    Continue pressing the button until 
    you are satisfied with the shape of the 
    image.

    8 - EPSON PowerLite 7850p Projector 6/03 Note: The image will be slightly shorter after adjusting. If it’s 
    important to maintain the correct aspect ratio, use the menu 
    system to perform keystone correction, as described below, 
    then adjust the Height setting as needed. 
    ❏Press the 
    Menu button on the remote control, select the 
    Setting menu, and press Enter. From the Setting menu, 
    select 
    H/V-Keystone in the Keystone menu and press 
    Enter. Select V-Keystone (for vertical keystone distortion) 
    or 
    H-Keystone (for horizontal keystone distortion) and 
    press 
    Enter. Use the   pointer button on the remote 
    control to adjust the keystone setting as needed.
    Using Quick Corner
    Use Quick Corner to correct the image shape when it’s 
    uneven on all sides. 
    1. Press the 
    Menu button on the remote control (or on the 
    projector’s control panel).
    2. Select the 
    Setting menu and press Enter. 
    3. From the Setting menu, select 
    Keystone and press Enter. 
    4. Select 
    Quick Corner and press Enter.
    You see this screen:
    5. Press the 
    Enter button to 
    select the corner you want to 
    adjust.
    6. Use the  pointer button on 
    the remote control (or the 
    arrow buttons on the 
    projector) to adjust the shape. 
    7. Repeat steps 5 and 6 as needed 
    to adjust any remaining 
    corners. 
    8. When done, press the 
    ESC button on the remote control to 
    exit the menu system.
    If 
    Quick Corner remains selected in the Keystone menu, the 
    Quick Corner screen appears whenever you press the 
    projector’s 
    Keystone buttons. You can then follow steps 5 
    through 8 above to correct the shape of your image, or press 
    ESC to exit Quick Corner.Correcting Computer Images
    If you’ve connected a 
    computer and the image 
    doesn’t look right or fit 
    properly on the screen, press 
    the 
    Auto button on the 
    remote control (or the 
    Auto/Enter button on the 
    projector’s control panel). 
    This automatically resets the projector’s tracking, sync, 
    resolution, and position settings. 
    Note: You must be projecting an image for this button to have 
    any effect. The 
    Auto button works only with computer images. 
    If vertical stripes appear in the projected image and the 
    Auto 
    button doesn’t correct the problem, hold down the 
    Shift 
    button on the projector’s control panel while pressing either 
    the 
    Tracking + or the Tracking – button.
    If the image appears fuzzy or flickers and the 
    Auto button 
    doesn’t correct the problem, hold down the 
    Shift button while 
    pressing either the 
    Sync + or Sync – button.
    Note: Also make sure you have selected the correct Computer or 
    BNC Input option in the Setting menu for your computer. See the 
    User’s Guide for more information.

    Shutting Down the Projector
    When you’ve finished using the projector, follow the 
    recommended procedure below to shut it down. This extends 
    the life of the lamp and protects the projector from possible 
    overheating. 
    Note: When the projector has not received any input signals for 30 
    minutes, it automatically turns off the projector lamp and enters 
    sleep mode. This conserves electricity, cools the projector, and 
    extends the life of the lamp. If you are done using the projector, 
    unplug the power cord. If you want to start projecting again, press 
    the P
    Power button. 
    You can turn off sleep mode using the 
    Sleep Mode option in the 
    Setting menu. If 
    Standby Mode has been set to Network ON 
    (in the Advanced1 menu), the lamp turns off but the projector 
    does not go into full sleep mode. It provides enough operation to 
    allow network access and allow the projector to be monitored or 
    controlled from a remote computer (see page 17).
    Follow these steps to turn off the projector:
    1. Turn off any equipment plugged into the projector. 
    2. To turn off the projector, press the red P
     Power button on 
    the projector or remote control. 
    You see a confirmation 
    message. (If you don’t want 
    to turn it off, press any 
    other button.)
    3. Press the P
     Power button again. The P power light flashes 
    orange for about 40 seconds as the projector cools down. 
    After the projector has cooled, the orange light stays on and 
    the exhaust fan shuts off.
    Caution: To avoid damaging the projector or lamp, never 
    unplug the power cord when the P power light is green or 
    flashing orange.
    To turn the projector on again, wait until the orange light 
    stops flashing. Then press the P
     Power button.
    4. If you extended the adjustable front foot, press up on the 
    blue foot release lever to retract it. If you’ve fine-tuned the 
    height by extending the projector’s rear feet, turn them in 
    the opposite direction to retract them.
    5. Replace the lens cap and unplug the power cord.
    6. If you’re using the remote control, turn it off to conserve 
    battery power.
    7. Disconnect any equipment plugged into the projector.
    Using the Remote Control
    The remote control 
    lets you access your 
    projector’s features from 
    up to 30 feet away, and
