2 PANORAMIC X-RAY BEAM ADJUSTMENT
NOTE In case the x-ray unit is equipped with optional AEC (Automatic Exposure Control), the
AEC calibration must be performed after the panoramic x-ray beam adjustment. See

2.1 Checking the panoramic beam position
Before the x-ray is used the position of the radiation beam must be checked. Remove the inner
covers from tube head assembly and the cassette drive assembly. Four screws hold the tube
head cover in position, these are located at the rear of the tube head assembly. The screws that
hold the cassette drive cover in place are located at the front and lower side of the cover. The pri-
mary slot mechanism is located under the tube head cover.

will come on.
The horizontal sector display will remain empty which indicates that the primary slot number 0
has been selected.
