    IMPORTANT INFORMATION
    RF Interference
    WARNING
    The Federal Communications Commission does not allow any
    modifications or changes to the unit EXCEPT those specified by
    NEC Soluctions (America), Inc. in this manual. Failure to comply
    with this government regulation could void your right to operate
    this equipment. This equipment has been tested and found to
    comply with the limits for a Class B digital device, pursuant to
    Part 15 of the FCC Rules. These limits are designed to provide
    reasonable protection against harmful interference in a residen-
    tial installation. This equipment generates, uses, and can radi-
    ate radio frequency energy and, if not installed and used in ac-
    cordance with the instructions, may cause harmful interference
    to radio communications. However, there is no guarantee that
    interference will not occur in a particular installation. If this equip-
    ment does cause harmful interference to radio or television re-
    ception, which can be determined by turning the equipment off
    and on, the user is encouraged to try to correct the interference
    by one or more of the following measures:
    •Reorient or relocate the receiving antenna.
    •Increase the separation between the equipment and receiver.
    •Connect the equipment into an outlet on a circuit different from
    that to which the receiver is connected.
    •Consult the dealer or an experienced radio / TV technician for help.
    In UK, a BS approved power cable with moulded plug has a Black (five
    Amps) fuse installed for use with this equipment. If a power cable is not
    supplied with this equipment please contact your supplier.
    Important Safeguards
    These safety instructions are to ensure the long life of your projector and
    to prevent fire and shock. Please read them carefully and heed all warn-
    ings.
    Installation
    1. For best results, use your projector in a darkened room.
    2. Place the projector on a flat, level surface in a dry area away from
    dust and moisture.
    To avoid premature lamp failure, do not tilt the front of the projector
    up or down by more than 10° from level.
    3. Do not place your projector in direct sunlight, near heaters or heat
    radiating appliances.
    4. Exposure to direct sunlight, smoke or steam can harm internal com-
    ponents.
    5. Handle your projector carefully. Dropping or jarring can damage in-
    ternal components.
    6. Do not place heavy objects on top of the projector.
    7. If you wish to have the projector installed on the ceiling:
    a. Do not attempt to install the projector yourself.
    b.The projector must be installed by qualified technicians in order
    to ensure proper operation and reduce the risk of bodily injury.
    c. In addition, the ceiling must be strong enough to support the pro-
    jector and the installation must be in accordance with any local
    building codes.
    d. Please consult your dealer for more information.
    8. Do not use the projector upside down on the surface of a tall cabinet,
    a table, or a floor. Doing so can hit the POWER button before you
    notice.

    Fire and Shock Precautions
    1. Ensure that there is sufficient ventilation and that vents are unob-
    structed to prevent the build-up of heat inside your projector. Allow at
    least 4 inches (10 cm) of space between your projector and a wall.
    2. Prevent foreign objects such as paper clips and bits of paper from
    falling into your projector.
    Do not attempt to retrieve any objects that might fall into your projec-
    tor. Do not insert any metal objects such as a wire or screwdriver into
    your projector. If something should fall into your projector, disconnect
    it immediately and have the object removed by a qualified NEC ser-
    vice personnel.
    3. Do not place any liquids on top of your projector.
    4. Do not look into the lens while the projector is on. Serious damage to
    your eyes could result.
    5. Keep any items such as magnifying glass out of the light path of the
    projector. The light being projected from the lens is extensive, there-
    fore any kind of abnormal objects that can redirect light coming out of
    the lens, can cause unpredictable outcome such as fire or injury to
    the eyes.
    6. Do not cover the lens with anything other than the built-in lens shutter
    while the projector is on. Doing so can lead to melting of the cover
    and possibly burning your hands due to the heat emitted from the
    light output.
    7. The projector is designed to operate on a power supply of 100-120 or
    200-240 V 50/60 Hz AC. Ensure that your power supply fits this re-
    quirement before attempting to use your projector.
    8. Handle the power cable carefully and avoid excessive bending.
    A damaged cord can cause electric shock or fire.
    9. If the projector is not to be used for an extended period of time, dis-
    connect the plug from the power outlet.
    10. Do not touch the power plug during a thunderstorm. Doing so can
    cause electrical shock or fire.
    11. Do not handle the power plug with wet hands.
    CAUTION
    1. Do not try to touch the ventilation outlet on the rear as it can become
    heated while the projector is turned on.
    2. Do no use the tilt-foot for purposes other than originally intended.
    Misuses such as gripping the tilt-foot or hanging on the wall can cause
    damage to the projector.
    3. When carrying the projector, heed the following:
    *Use the supplied soft carrying case. Before putting the projector in
    the soft carrying case, be sure to close the lens shutter so as not
    to mar the lens.
    *Do not handle the projector roughly.
    *Do not send the soft carrying case by parcel delivery service or
    cargo shipment. The projector inside the soft carrying case could
    be damaged. (However, it is possible to use it as a carrier case on
    board.)
    4. Select “High” in the Fan mode if you continue to use the projector for
    consecutive days. (From the menu, select [To Advanced Menu] →
    [Setup 2] → [Fan Mode].)
    5. Do not unplug the power cable from the wall outlet under any one of
    the following circumstances.
    Doing so can cause damage to the projector:
    *While the Hour Glass icon appears.
    *While the cooling fans are running. (The cooling fans continue to
    work for 60 seconds after the projector is turned off).
    Whats in the Box?Make sure your box contains everything listed. If any pieces are missing,
    contact your dealer.
    Please save the original box and packing materials if you ever need to
    ship your LT170 Projector.

    projector cabinet
    Actual operating range may differ from the above drawing.
    •The infrared signal operates by line-of-sight up to a distance of about
    22 feet/7 m and within a 60-degree angle of the remote sensor on the
    projector cabinet.
    •The projector will not respond if there are objects between the remote
    control and the sensor, or if strong light falls on the sensor. Weak bat-
    teries will also prevent the remote control from properly operating the
    projector.
