transfer is complete, the evaluation of the distortion calibration is
displayed in the message window.
If the information in the message window indicates that
calibration was not successful, check the calibration phantom to
make sure that it is not damaged.
If the phantom checks out OK (all balls are present and correctly
positioned), repeat the procedure starting with point d) as often
as required until the calibration is OK.
If you have repeated the procedure three times and still have not
attained a positive result, please contact the SIRONA Customer
Service Center (CSC).
