Manually position the rotating unit so that the center line that runs through the tube head and film
cassette mechanism is at a right angle to the wall. Slide the alignment pin through the hole in the
top of the vertical carriage so that it goes into the positioning hole in the rotating unit.
Adjust the position of the rotating unit by holding the cassette carriage. Never use the
tube head to adjust the position.
Leave the ball phantom tool in position and place the alignment ruler in position between the pri-
mary slot and the secondary slot as described earlier. Measure the distance between the line on
the alignment ruler and the x-line on the ball phantom (Fig. 26). The distance must be less than
1mm.

If the distance between the line on the alignment ruler and the x-line on the ball phantom is more
than 1mm, the secondary slot position must be adjusted. Move the secondary slot towards the
ball phantom's x-line until the distance is less than 1mm.
