5. Move the image up or down by adjusting the small mirror. To do this, first loosen
the upper thumbscrews on both sides of the small mirror. Then gently push the
mirror away from you to lower the image, or pull it towards you to raise the
image. When the image is in the right position, tighten the thumbscrews.
NOTE: Once the mirror is in position, there should be minimal keystone error. If there is a
significant keystone error, re-adjust the small mirror to minimize the keystone error, even if this
places the image too high or too low on the screen. Then, if the image is too high or too low,
adjust the mirror stand’s adjustable feet to raise or lower the image to the correct position
(page 18 and page 19).
