During the exposure the AEC-signal value is shown on the main display. Set this value to approx.
60 with the gain trimmer located on the Cassette limit PCB. Turning the trimmer clockwise
decreases the value and turning it counterclockwise increases it. Repeat the adjustment until the
correct value has been reached.
NOTE The final adjustment of the AEC-signal during the exposure must be done in the normal
mode.

exit the film density adjustment and the service modes and the signal can be seen on the
main display.
To exit the service mode press the CEPH key briefly.
Drive the x-ray unit to the exposure position by pressing the ready key.
