D-16 Planmeca Proline EC X-ray unit
PATIENT POSITIONING MECHANISM
Technical Manual
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 if you are not already in it.
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
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 with the CTL-key.
Manually position the rotating unit so that the center line that runs through the tubehead and
film cassette mechanism 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.

NOTE Adjust the position of the rotating unit by holding the cassette carriage. Never use the
