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
instructions given in section “AUTOMATIC EXPOSURE CONTROL (AEC) CALIBRA-

Before the X-ray is used the position of the radiation beam must be checked. Remove the
inner cover from tubehead assembly. Four screws hold the tubehead cover in position, these
are located at the rear of the tubehead assembly. The primary slot mechanism is located
under the tubehead cover.

remote control. Stop pressing the exposure button when the tubehead has rotated to a con-
venient position for viewing the secondary slot.
