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.
When adjusting the position of the lens, if you find that the dial does not move, it may have been beyond the adjustment range, do
•
not forcibly rotate the dial , otherwise there is a risk of damage. When there is a lack of image, it has been beyond the adjustment
range, adjust in the opposite direction to the range of full image.
