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.
The final adjustment of the AEC-signal during the exposure must be done in the normal
mode.
In the normal mode the AEC-signal is only shown on the main display if you previously
were in the film density adjustment mode. In case the AEC-signal is not shown on the
main display, enter the service mode and enter the film density adjustment mode. Then
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.
Take an exposure. Note that you can stop radiation in the middle of the exposure (approx. 4 sec-
onds after starting the exposure). An error code 00 will appear on the display and start to flash.
Press the CTL-key to clear the error code.
