4. Repeat the procedure starting at Step 2 until the values in the menu's
text boxes are equal to "zero". This means that adjustment was
performed successfully.
IMPORTANT:If automatic adjustment fails to produce values equal to
zero, calculate the adjustment values manually and overwrite the
values in the menu's text boxes with these values [ → 226].
5. If adjustment is OK (the adjustment values in the text boxes are equal
to zero), save the values. [ → 206]
6. Remove the OP XG ceph adjustment phantom from the pan slot on
the unit.

Manual adjustment: Ceph - Primary diaphragm
The manual adjustment procedure is similar to the one for automatic
adjustment. The only difference is that the default adjustment values
calculated automatically by SIDEXIS XG in the
"Ceph - Primary
diaphragm"
menu are overwritten.
1. Start the
"Ceph - Primary diaphragm"
adjustment procedure as
described in the chapter entitled "Automatic adjustment: Ceph -
Primary diaphragm (standard) [ → 224]".
2. Once you have taken the exposure, measure distances S1, S2, S3,
and S4 with the SIDEXIS XG measuring ruler.
S1: distance to the top edge of the image
S2: distance from the right edge of the radiation-exposed surface to
the middle of the center pin
S3: width of radiated area
S4: distance to the bottom edge of the image
Tip: To facilitate the measuring procedure, you can invert or color the
image in SIDEXIS XG (see also "SIDEXIS XG Operator's Manual").
