quickly. If the orientation is correct, the CCTV image of the saw cuts will scan
accurately along the cross hairs.

rotate it, adjust the Theta Adjust Knurled Screw which is located at an angle on
the left side of the frame holder.
a. If the frame is too far off for this correction, set the holder back to the
middle and then open the holder and remove the locator pins.
b. While moving the holder back and forth, rotate the frame until the
streets are close to the cross hairs.
c. Close the holder and use the Theta Adjust Knurled Screw to fine adjust
the ring.
