Tighten the screws, and remove the alignment pin.
Take another ball phantom picture to check the alignment again. Readjust if necessary.
Adjustment in ball phantom's x-direction
If the patient positioning mechanism is too far forward or too far backwards the fore/aft posi-
tion must be adjusted and the new position programmed into the memory.
Enter the test mode.
Touch the ready field to drive the X-ray unit to the exposure position. When the X-ray unit is
ready the ready field is green.
Start to take a test exposure by pressing and holding down exposure button on the remote
control. Stop pressing the exposure button after about two seconds so that the rotating unit
stops moving.
An error code will appear on the display. Clear the error code from the display.
Manually adjust the rotating unit position so that the center line that runs through the tube
head and sensor head is at a right angle to the wall. Slide the alignment pin through the hole
in the top of the vertical carriage so that it goes into the positioning hole in the rotating unit.
