Press the collimator selection key to reposition the third collimator slot (the first cephalometric
slot). The number 5 will appear on the display. Note that the third collimator slot (the first ceph
slot) is used to take both vertical symmetric and vertical asymmetric exposures. The slot is
moved slightly to accommodate the two exposure views.
Stand behind the tube head and protect yourself from radiation. Press and hold down the expo-
sure button. The image of the radiation beam from slot number 5 will appear on the alignment
tool.
The radiation beam must appear within the borders of the rectangle marked on the alignment
tool. If it does not refer to the section
“Primary slot calibration” on page D-7. The adjustment is
performed in the same way as when adjusting the standard panoramic slot.
