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. Do not force to turn the dials. Doing so may damage the dials.
• 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.
