    							Chapter 1   Preparation
    This chapter describes things you need to know or check before using the\
     projector.
    ENGLISH - 17  
    						
    							Precautions for use
    Cautions when transporting
     fWhen transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts. Doing so may damage the internal parts and result in malfunctions.
     fDo not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
    Cautions when installing
     rDo not set up the projector outdoors.
     fThe projector is designed for indoor use only. 
     rDo not use under the following conditions.
     fPlaces where vibration and impacts occur such as in a car or vehicle: Do\
    ing so may damage the internal parts and result in malfunctions.
     fLocations near the sea or areas affected by corrosive gas: Corrosion may damage internal components or cause the projector to malfunction. 
     fNear the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases due to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector or other equipment, or the air from the air conditioner does not blow toward the \
    front of the projector.
     fPlaces with sharp temperature fluctuations such as near lights (studio lamp): Doing so may shorten the life of the lamp, or result in deformation of the outer case due to heat, which may cause mal\
    functions. 
    The operating environment temperature of the projector should be between 0 °C (32 °F) and 40 °C (104 °F)*1 when using it 
    at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 30 °C (86 °F) when using it at high altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level).
    *1 When the operating environment temperature of the projector is between 35 °C (95°F) and 40 °C (104 °F), the lamp mode 
    will change to [ECO] automatically.
     fNear high-voltage power lines or near motors: Doing so may interfere with the operation of the projector .
     rBe sure to ask a specialized technician when installing the product to a\
     ceiling.
    This requires an optional ceiling mount bracket. Be sure to use the Proj\
    ector Mount Bracket together with the ceiling mount bracket for high ceilings or low ceilings.
    Model No.: 
    ① ET-PKL100H (for high ceilings), ET-PKV400B (Projector Mount Bracket) 
    ② ET-PKL100S (for low ceilings), ET-PKV400B (Projector Mount Bracket) 
     rFocus adjustment
    The projection lens is thermally affected by the light from the light source, making the focus unstable in \
    the period just after switching on the power. It is recommended that the images are projected continuously for at le\
    ast 30 minutes before the focus is adjusted.
     rWhen using the projector in the elevation of below 1 400 m (4 593'), m\
    ake sure [HIGH ALTITUDE MODE] 
    is set to [OFF].
    Failure to do so may shorten the life of the internal parts and result in malfunctions.
     rWhen using the projector in the elevation of above 1 400 m (4 593') an\
    d below 2 000 m (6 562'), make 
    sure [HIGH ALTITUDE MODE] is set to [HIGH1].
    Failure to do so may shorten the life of the internal parts and result in malfunctions.
     rWhen using the projector in the elevation of above 2 000 m (6 562') an\
    d below 2 700 m (8 858'), make 
    sure [HIGH ALTITUDE MODE] is set to [HIGH2].
    Failure to do so may shorten the life of the internal parts and result in malfunctions.
     rDo not install the projector at elevations of 2 700 m (8 858') or high\
    er above sea level.
    Failure to do so may shorten the life of the internal parts and result in malfunctions.
     rDo not tilt the projector or place it on its side.
    Do not tilt the projector body more than approximately ±40 degrees vertically or ±15 degrees horizontally . Over tilting may 
    result in shortening the life of the components.

    							 rCautions when setting the projectors
     fIf you want to use the projector other than the way of setting on the desk/floor with the adjustable feet or mounting on the ceiling, use the three screw holes for ceiling mounting (as shown below) to fix the projector. (Screw: M4; Depth of the screw hole: 8 mm (5/16"); Torque: M4 1.25 ± 0.2 N·m) In addition, always keep a gap of more than 20 mm (25/32") between the bottom of the projector and installation surface. Make sure that there is no clearance of at least 20 mm (25/32″) between the screw holes for ceiling mounting and the installation surface by inserting supports (metallic) between them.
     fDo not stack the projectors.
     fDo not use the projector supporting it by the top.
     fDo not block the ventilation ports (intake and exhaust) of the projector.
     fAvoid heating and cooling air from the air conditioning system directly blow to the ventilation ports (intake and exhaust) of 
    the projector.
     fDo not install the projector in a confined space.  
    When placing the projector in a confined space, a ventilation and/or air conditioning system is required. Exhaust heat may 
    accumulate when the ventilation is not enough, triggering the protection\
     circuit of the projector.
    Security
    Take safety measures against following incidents.

    							Disposal
    To dispose of the product, ask your local authorities or dealer for corre\
    ct methods of disposal.
    The lamp contains mercury. When disposing of used lamp units, contact your local authorities or dealer for correct methods of 
    disposal.
    Cautions on use
     rTo get a good picture quality
     fIn order to view a beautiful image in higher contrast, prepare an approp\
    riate environment. Draw curtains or blinds over 
    windows and turn off any lights near the screen to prevent outside light or light from indo\
    or lamp from shining onto the 
    screen.
     rDo not touch the surface of the projector lens with your bare hands.
    If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto 
    the screen.
    Attach the supplied lens cap to the projection lens when you do not use \
    the projector.
     rLCD panel
    The LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that 
    such phenomena do not indicate malfunction. If still images are projecte\
    d for a long time, a residual image may remain on the 
    LCD panel. Note that the residual image may not disappear.
     rOptical parts
    When the operating environment temperature is high or in environments where lots of dust, cigarette smoke, etc. is present, 
    the replacement cycle of the LCD panel, polarizing plate and other optical parts may be shorter even if used for less than one 
    year. Consult your dealer for details.
     rLamp
    The luminous source of the projector is a mercury lamp with high interna\
    l pressure.
    A high-pressure mercury lamp has the following characteristics.
     fThe luminance of the lamp will decrease by duration of usage.
     fThe lamp may burst with a loud sound or have its service life shortened \
    because of shock, chipping, or degradation due to 
    cumulative runtime.
     fThe life of the lamp varies greatly depending on individual specificities and usage conditions. In particular, continuous use 
    over 12 hours and frequent switching off/on of the power greatly deteriorate the lamp and affect the lamp life.
     fIn rare cases, the lamp burst shortly after the projection.
     fThe risk of bursting increases when the lamp is used beyond its replacem\
    ent cycle. Make sure to replace the lamp unit 
    consistently. (“When to replace the lamp unit” (x page 128), "Replacing the Lamp unit" (x page 128)) 
     fIf the lamp bursts, gas contained inside of the lamp is released in a fo\
    rm of smoke.
     fIt is recommended to store replacement lamp for contingency.
     rComputer and external device connections
     fWhen connecting a computer or an external device, read this manual carefully regarding the use of power cords and 
    shielded cables as well.
