Press the return key to drive the cassette to the loading position, remove the cassette and proc-
ess the film.
Compare the film to the reference film: the film must be as dark as the reference film. Repeat the
procedure with different mA values until the correct film density is achieved, and then select the
density value that gives the right mA value as follows.
Enter the service mode: press the CTL-key and simultaneously press and hold down the cepha-
lometric mode selection (CEPH) key until the temperature of the tube head appears on the dis-
play (about four seconds). The ready key indicator light will start to flash. This indicates that you
have entered the service mode.
To change the density value enter the film density adjustment mode: press the control key and
then press the pan key until the density value, indicated with "d", is shown on the main display.
Change the value with the height adjusting keys.
Select the density value that corresponds the mA value, e.g. if the mA value is 7mA, select the
density value -1.
Exit the film density adjustment mode by pressing the ready key.
