    Projector Placement
    You can place the projector on almost any flat surface to project an image.
    You can also install the projector in a ceiling mount if you want to use it in a
    fixed location. An optional ceiling mount is required when suspending the
    projector from a ceiling.
    Note the following points when selecting a projector location:
    • Place the projector on a sturdy, level surface or install it using a compatible
    mount.

    • Leave plenty of space around and under the projector for ventilation, and
    do not place it on top of or next to anything that could block the vents.
    • Position the projector within reach of a grounded electrical outlet or
    extension cord.
    • Place the projector parallel to the screen.

    18

    a

    If you cannot install the projector parallel to the screen, correct
    keystone distortion using the projector controls.

    Warning
    • You must install a ceiling mount when suspending the projector from a ceiling.
    If you do not install the projector correctly, it could fall and cause damage or
    injury.
    • Do not use adhesives on the ceiling mount fixing points to prevent the screws
    from loosening, or use lubricants, oils, or similar substances on the projector; the
    projector case may crack causing it to fall from its ceiling mount. This could
    cause serious injury to anyone under the ceiling mount and could damage the
    projector.
    • Do not cover the projector's air intake or air exhaust vents. If the vents are
    covered, the internal temperature could rise and cause a fire.
    • Do not install the projector on an unstable surface or in a location beyond the
    weight specifications of the projector. Otherwise, it could fall or topple causing
    an accident and injury.
    • When installing the projector in a high position, take measures to prevent falling
    by using wires to ensure safety in an emergency, such as an earthquake, and to
    prevent accidents. If it is not installed correctly, it could fall causing an accident
    and injury.

    Attention

    • Do not operate the projector on its side. This may cause the projector to
    malfunction.
    • If you are using the projector at altitudes above 1500 m, set the High Altitude
    Mode setting to On in the projector's Extended menu to ensure the projector's
    internal temperature is regulated properly.
    s Extended > Operation > High Altitude Mode
    • Try not to setup the projector in locations subject to high humidity and dust, or
    in locations subject to smoke from fires or tobacco smoke.

    Turning On the Projector
    Warning
    • Never look into the projector lens when the lamp is on. This can damage your
    eyes and is especially dangerous for children.
    • When turning on the projector at a distance using the remote control, make sure
    there is no one looking into the lens.
    • During projection, do not block the light from the projector with a book or other
    objects. If the light from the projector is blocked, the area on which the light
    shines becomes hot which could cause it to melt, burn, or start a fire. Also, the
    lens may get hot due to the reflected light which could cause the projector to
    malfunction. To stop projection, use the A/V Mute function, or turn off the
    projector.
    • A mercury lamp with high internal pressure is used as the projector's light
    source. If the lamp is subjected to vibrations or shocks, or if it is used for an
    overly extended length of time, the lamp may break or it may not turn on. If the
    lamp explodes, gases may escape and small fragments of glass may be scattered
    which could cause an injury. Be sure to observe the instructions below.
    • Do not disassemble or damage the lamp or subject it to any impacts.
    • Do not bring your face close to the projector while it is in use.
    • Particular care should be taken when the projector is installed to a ceiling, as
    small pieces of glass may fall down when the lamp cover is removed. When
    cleaning the projector or replacing the lamp yourself, be very careful not to
    allow such pieces of glass to get into the eyes or mouth.
    If the lamp breaks, ventilate the area immediately, and contact a doctor if any
    fragments of broken glass are inhaled or get into the eyes or mouth.

    a

    • When the Direct Power On setting is set to On in the projector's
    Extended menu, the projector turns on as soon as you plug it in.
    Note that the projector also turns on automatically in cases such as
    recovery from a power outage.
    s Extended > Operation > Direct Power On
    • If you select a specific port as the Auto Power On setting in the
    projector's Extended menu, the projector turns on as soon as it
    detects a signal or cable connection from that port.

    Cleaning the Lens
    Clean the projector's lens periodically, or whenever you notice dust or
    smudges on the surface.
    • To remove dust or smudges, gently wipe the lens with lens-cleaning paper.
    • To remove stubborn smudges, moisten a soft, lint-free cloth with lens
    cleaner and gently wipe the lens. Do not spray any liquid directly on the
    lens.

    Warning
    Do not use a lens cleaner that contains flammable gas. The high heat generated
    by the projector lamp may cause a fire.

    Attention

    Do not use glass cleaner or any harsh materials to clean the lens and do not
    subject the lens to any impacts; otherwise, it could be damaged. Do not use
    canned air, or the gases may leave a flammable residue.

    Cleaning the Projector Case
    Before cleaning the projector case, turn off the projector and unplug the
    power cord.
    • To remove dust or dirt, use a soft, dry, lint-free cloth.
    • To remove stubborn dirt, use a soft cloth moistened with water and mild
    soap. Do not spray liquid directly on the projector.

    Attention

    Do not use wax, alcohol, benzene, paint thinner, or other chemicals to clean the
    projector case. These can damage the case. Do not use canned air, or the gases
    may leave a flammable residue.

    Air Filter and Vent Maintenance
    Regular filter maintenance is important to maintaining your projector. Clean
    the air filer when a message appears telling you the temperature inside the
    projector has reached a high level. It is recommended that you clean these
    parts over a 2000-hour period. Clean them with shorter periodicity if you use
    the projector in a particularly dusty environment.

    Attention

    If regular maintenance is not performed, your Epson projector will notify you
    when the temperature inside the projector has reached a high level. Do not wait
    until this warning appears to maintain your projector filter as prolonged exposure
    to high temperatures may reduce the life of your projector or lamp.

    Projector Lamp Maintenance
    The projector monitors the number of hours the lamp is used and displays
    this information in the projector's menu system.
    Replace the lamp as soon as possible when the following occurs:
    • The projected image gets darker or quality declines
    • A message is displayed when you turn on the projector telling you to replace
    the lamp (the message is displayed 100 hours before the expected end of the
    lamp life and appears for 30 seconds)

    • The projector's power indicator is flashing blue and its lamp indicator is
    flashing orange.

    145

    Attention

    • If you continue to use the lamp after the replacement period has passed, the
    possibility that the lamp may explode increases. When the lamp replacement
    message appears, replace the lamp with a new one as soon as possible, even if it
    is still working.
    • Do not repeatedly turn off the power and then immediately turn it back on.
    Turning the power on and off frequently may shorten the lamp's operating life.
    • Depending on the characteristics of the lamp and the way it has been used, the
    lamp may become darker or stop working before the lamp warning message
    appears. You should always have a spare lamp unit ready in case it is needed.
    • We recommend the use of genuine Epson replacement lamps. The use of nongenuine lamps may affect projection quality and safety. Any damage or
    malfunction caused by the use of non-genuine lamps may not be covered by
    Epson's warranty.

    transferred at the highest quality possible. It also provides an
    encryption function for the digital signal.

    HDTV

    An abbreviation for High-Definition Television that refers to
    high-definition systems which satisfy the following conditions:
    • Vertical resolution of 720p or 1080i or greater (p =
    Progressive, i = Interlace)
    • Screen aspect ratio of 16:9

    Infrastructure
    mode

    A method for wireless LAN connection in which devices
    communicate through access points.

    Interlace

    Transmits information needed to create one screen by sending
    every other line, starting from the top of the image and working
    down to the bottom.
    Images are more likely to flicker because one frame is displayed
    every other line.

    IP Address

    A number to identify a computer connected to a network.

    MHL

    An abbreviation for Mobile High-definition Link, a standard
    for connection interfaces aimed at mobile devices such as
    smartphones and tablets.
    Images can be transferred at high quality and at high speeds
    without compressing the digital signal, and also charges
    connected devices.

    Progressive

    Projects information to create one screen at a time, displaying
    the image for one frame.
    Even though the number of scan lines is the same, the amount
    of flicker in images decreases because the volume of
    information has doubled compared with an interlace system.

    Refresh Rate

    The light-emitting element of a display maintains the same
    luminosity and color for an extremely short time.
    Because of this, the image must be scanned many times per
    second to refresh the light-emitting element.
    The number of refresh operations per second is called the
    Refresh rate and is expressed in hertz (Hz).

    Component Video A method that separates the video signal into a luminance
    component (Y), and a blue minus luminance (Cb or Pb) and a
    red minus luminance (Cr or Pr).
    Composite Video

    A method that combines the video signal into a luminance
    component and a color component for transmission down a
    single cable.

    Contrast

    The relative brightness of the light and dark areas of an image
    can be increased or decreased to make text and graphics stand
    out more clearly, or to make them appear softer. Adjusting this
    particular property of an image is called contrast adjustment.

    DHCP

    An abbreviation of Dynamic Host Configuration Protocol, this
    protocol automatically assigns an IP address to equipment
    connected to a network.

    DICOM

    An acronym for Digital Imaging and Communications in
    Medicine.
    An international standard that defines image standards and a
    communications protocol for medical images.

    Gateway Address

    This is a server (router) for communicating across a network
    (subnet) divided according to subnet mask.

    HDCP

    HDCP is an abbreviation for High-bandwidth Digital Content
    Protection.
    It is used to prevent illegal copying and protect copyrights by
    encrypting digital signals sent over DVI and HDMI ports.
    Because the HDMI port on this projector supports HDCP, it
    can project digital images protected by HDCP technology.
    However, the projector may not be able to project images
    protected with updated or revised versions of HDCP
    encryption.

    SDTV

    An abbreviation for Standard Definition Television that refers
    to standard television systems which do not satisfy the
    conditions for HDTV High-Definition Television.

    sRGB

    An international standard for color intervals that was
    formulated so that colors that are reproduced by video
    equipment can be handled easily by computer operating
    systems (OS) and the Internet. If the connected source has an
    sRGB mode, set both the projector and the connected signal
    source to sRGB.

    SSID

    SSID is identification data for connecting to another device on
    a wireless LAN. Wireless communication is possible between
    devices with the same SSID.

    Subnet Mask

    This is a numerical value that defines the number of bits used
    for the network address on a divided network (subnet) from the
    IP address.

    SVGA

    A screen size standard with a resolution of 800 (horizontal) ×
    600 (vertical) dots.

    SXGA

    A screen size standard with a resolution of 1,280 (horizontal) ×
    1,024 (vertical) dots.

    Sync.

    The signals output from computers have a specific frequency.
    If the projector frequency does not match this frequency, the
    resulting images are not of a good quality.
    The process of matching the phases of these signals (the relative
    position of the crests and the troughs in the signal) is called
    Synchronization.
    If the signals are not synchronized, flickering, blurriness, and
    horizontal interference occur.

    Tracking

    The signals output from computers have a specific frequency.
    If the projector frequency does not match this frequency, the
    resulting images are not of a good quality.
    The process of matching the frequency of these signals (the
    number of crests in the signal) is called Tracking.
    If Tracking is not carried out correctly, wide vertical stripes
    appear in the signal.

    VGA

    A screen size standard with a resolution of 640 (horizontal) ×
    480 (vertical) dots.

    XGA

    A screen size standard with a resolution of 1,024 (horizontal) ×
    768 (vertical) dots.

    WXGA

    A screen size standard with a resolution of 1,280 (horizontal) ×
    800 (vertical) dots.
