Press and hold the P key until you have heard two audible signals. Select the cephalometric
exposure mode number 5 with the program selection keys. The text CPH5 will appear on the
main 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 tubehead and protect yourself from radiation. Press and hold down the
exposure 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 adjustment, Planmeca Proline EC Pan/
Ceph X-ray” on page D-8. The adjustment is performed in the same way as when adjusting
the standard panoramic slot.
