    When the lens is attached to the projector and
    images are being projected onto the screen, the
    peripheral focus may be out of focus in some
    localized areas. If this happens, insert the spacer
    in between the lens attachment and the lens to
    correct the focus.

    Inserting the spacers corrects the distance for best
    diagonal focus at the screen.
    The corrected distance is determined by the
    thickness of the spacers that are used. As a guide,
    the distance is adjusted by approximately 30 mm
    for each 0.1-mm thickness of the spacers.
    There are three types of spacers provided, and
    there are four of each spacer type. Use these
    spacers to correct the distance as required.
