3. Turn in set screw D lightly (by hand) allowing the image to move slightly (1/3 to 1/2 of a square).

5. Tighten nut 4 until the offset of the image movement created in step 3 is canceled.
Tip: The amount of image movement in step 3 will determine how tight the nut in step 5 will need to be turned to return the
image to its original position.
