Make sure that the primary slot number 0 is selected (the horizontal sector display is empty).
Load the cassette with a film and slide it into the cassette holder.
Protect yourself from radiation and press the exposure button.
CAUTION Radiation is generated when the exposure button is pressed. Take adequate protection
measures. Keep the exposure time as short as possible.
During the exposure the AEC-signal is shown on the main display. Adjust the slot position in hor-
izontal direction until the signal reaches its maximum value as follows.
Press the CTL and press and hold down the primary slot key for 4 seconds to enter the beam
alignment mode.
Adjust the position of the beam by pressing the patient positioning (mm) keys. The minus key will
move the slot mechanism, and beam to the left, and the plus key will move the slot mechanism,
and beam to the right. The primary slot adjustment in horizontal direction is described in section
“Radiation beam too far to the right or left” on page D-8.
Check the x-ray beam position with the beam alignment tool after the adjustment. If the beam
image is not within the borders of the rectangle marked on the alignment tool, adjust the beam
position slightly.
After the primary slot number 0 has been adjusted, select the primary slot number 1 and adjust it
in the same way. Make sure that the value for the primary slot number 1 equals to the value for
the primary slot number 0.
Check the x-ray beam position with the beam alignment tool after the adjustment. Adjust the
beam position slightly, if needed.
NOTE Remove the AEC calibration filter from the primary slot before selecting the primary slot
number 1. Position the AEC calibration filter to the front of the second primary slot before
adjusting the AEC-signal.
