NOTE
If the strips on the phantoms light up at all it means overex-
posure of the system, and you cannot continue adjustment.
In this case, repeat the diaphragm adjustment procedure
and then check the radiation field again. If the lighting strips
still light up during the re-check of the radiation field, contact
the SIRONA Customer Service Center (KSC) to solve the
problem.
To confirm that the lighting strips on the distortion phantom
do not light up, click the check box underneath the message
window.
• The box will appear checked.
• Continue the calibration procedure with dosimetry.

NOTE
Leave the distortion phantom on the unit for the next calibra-
tion step.
