•
Select SYSTEM/CALIBRATION.
•
Enter the following parameters in the list boxes:
Exposure data e.g.= exposure = 4; 70KV; 1.8 mAs, SID 150cm

If error messages ("Too much/little dose", "Collimator is used") are displayed
during calibration, the KV and mAs values have to be adjusted accordingly.
If the calibration is unsuccessful, check the calibration settings.
The KV and mAs settings may have to be adjusted.
If the calibration continues to be unsuccessful, start the detector
self-test (see Troubleshooting Guide SPR8-230.240.30...) or notify
the Uptime Support Center.
Four exposures are required. No error messages should be displayed. The cali-
bration completion is indicated.
