    Lens replacement should be performed by the qualified service
    personnel.
    It should be followed by this procedure precisely.
    Before an attempt to replace the lens, confirm the model number
    (both the LCD projector and the lens) and prepare the proper lens.
    Lens installation is different in cabinet design (Type A and B).
    Before installing the lens, check cabinet design should be made.
    The lens cover is on the lens for protection. Be sure to remove the
    lens cover before installation.
    Please avoid the lens replace in the place where a lot of dust
    exists. It causes the image quality to be ruined when garbage and
    dust enter the projector.
    When installing or removing the lens, be careful not to stain,
    scratch or damage the lens.
    If you have any questions, contact the dealers.

    							Set up the projector in the place where it is to be used, turn on the power and project a picture.
    Adjust the position of the projector to suit the projection position.
    1. Turn the focus ring to adjust the focus at the center of the screen. The focus at the edges of the
    screen may not be as sharp as at the center of the screen. 
    2. If the focus cannot be set correctly at the center of the screen, it will be necessary to move the
    lens unit forward or back relative to the flange in order to adjust the back focus. Carry out this
    adjustment according to the procedure given below.

    FOCUS RING
    ROULETTE PIN
    NOTE: Please remove 3 pins when you install it in the cabinet of B type.
    a. Turn the fixing roulette about 1/4 of a turn counterclockwise to release it. The roulette can be
    released more easily if you place the tip of your finger on the pin where the roulette is.
    b. If the current focal point is somewhere forward of the screen, turn the focus ring clockwise;
    if the focal point is somewhere behind the screen, turn the focus ring counterclockwise, and
    then turn the precision lens unit (the focus ring and the fixing roulette) 5 degrees.
    c. Turn the focus ring to adjust the focus at the center of the screen. (Be careful not to move the
    whole of the lens unit at this time.)
    d. Repeat steps b and c until correct focus is obtained.
    Note: If the lens unit is difficult to move when carrying out the above procedure, turn the fixing
    roulette counterclockwise a further 1/4 of a turn.
    e. Once the above adjustment is complete and the picture is in focus, turn the fixing roulette
    clockwise until it is tightened securely. Do this carefully, otherwise the focus may become
    disrupted. If the roulette is not tightened securely, it may become difficult to remove the lens
    during lens replacement.
    3. If the focus cannot be correctly adjusted even after the above procedure has been carried out,
    try adjusting by carrying out the procedure given below.
    a. Set the distance between the screen and the edge of the lens to 0.77 m and project a picture.
    b. Turn the roulette counterclockwise to release it.
    c. Turn the focus ring counterclockwise as far as it will go, and then move the lens unit (the
    focus ring and the fixing roulette) to adjust the focus at the center of the screen.
    d. Check that the focus at the center of the screen is correct, and then turn the fixing roulette
    clockwise until it is tightened securely. Check that the focus ring is still turned
    counterclockwise as far as it will go at this time.
    e. Return the projector to its original setup location and repeat steps 1 and 2 to adjust the focus.
