Release the screws fixing the positioning sphere "A" (no more than one
turn) and acting on the micrometric regulation screw "C", proceed to
regulate (rotation) the skull clamp group "B".
If the larger diameter (ring further from the film cassette) is further from
the nose rest than the ring showing the small circle on the film (ring
closer to the cassette film), it will be necessary to unscrew the regulation
screw "C" and move manually the sphere holder "E" counterclockwise .
In the opposite case regulation screw "C" has the be screwed in and the
sphere holder will move automatically clockwise. Once the centering has
been achieved (an exposure is necessary to verify it) screws "A" need to
be tightened and regulation screw "C" has to be blocked by the dedicated
safety bolt "D".
