WARNING
When performing the following tests, be sure to observe the radiation
protection regulations applicable in your country (see operating instruc-
tions).
CAUTION
Before starting the service routines for system adjustment, make sure that no
unit movements are active (especially diaphragm travels)! Otherwise the sys-
tem may become inoperable in rare cases.
NOTE
i
“Radiation” is signaled with the message “X-RAY active!” (only for XG

Coarse and precision adjustment using the Diaphragm/system
adjustment menu in SIDEXIS XG
NOTE
i
The Pan - Sensor adjustment, Pan - Diaphragm and Ceph - Fixed point of ro-
tation submenus provide a coarse adjustment and a precision adjustment
(precision adjustment is preset).
Always try to use precision adjustment first when adjusting the unit. In most
cases, previous coarse adjustment is not necessary.
With SIDEXIS Version V02.20 and higher, a message window indicates when
a coarse adjustment is necessary.
Only if you cannot achieve your goal with precision adjustment, e.g. if the
exposed area is completely outside the image field, should you perform a
coarse and then a precision adjustment.
If a coarse adjustment proves necessary, deactivate the
PRECISION ADJUSTMENT
check box and follow the adjustment steps de-
scribed in the present chapter to perform a coarse adjustment.
The steps and correction procedure required for coarse adjustment are iden-
tical to those for precision adjustment. The only difference between the two
modes is the size of the image area considered. Furthermore, there are fewer
auxiliary lines in the coarse adjustment mode.
