If the patient positioning mechanism is too near or too far from the column it will have to be cen-
tered.
Remove the cover from the lower shelf. Replace the ball phantom tool.
Enter the test mode.
Press the ready key to drive the x-ray unit to the exposure position. When the x-ray is ready the
indicator light will come on.
Start to take a test exposure by pressing and holding down exposure button on the remote con-
trol. Stop pressing the exposure button about halfway through the exposure cycle so that the
rotating unit stops moving.
An error code will appear on the display. Clear the error code from the display by pressing the
CTL-key.
Manually position the rotating unit so that the center line that runs through the tube head and film
cassette mechanism is parallel to the wall to which the x-ray is secured. Slide the alignment pin
through the hole, nearest the column, in the top of the vertical carriage so that it goes into the
positioning hole in the rotating unit. (Fig. 20)
