Turn this clockwise or counterclockwise to adjust the projection position in the vertical direction.
Approximate turning range: About 6 turns counterclockwise, about 2 turns clockwise when the lens is at the center

Turn this clockwise or counterclockwise to adjust the projection position in the horizontal direction.
Approximate turning range: About 1 turn counterclockwise, about 1 turn clockwise when the lens is at the center
position.
NOTE:
• The dials can be turned more than one full turn, but the projection position cannot be moved more than the range indicated on
the following page.
• If the lens is shifted to the maximum in the diagonal direction, the edges of the screen will be dark or shaded.
• The vertical shift adjustment must be finished with an image shifted upward. If you finish the vertical shift adjustment with an
image shifted down, the zoom/focus adjustments or strong shaking may cause a projected image to slightly shift down.
• The lens shift function cannot be used when using the separately sold NP11FL lens.
