WARNING
DO NOT ADJUST THE POSITION OF THE PRIMARY SLOT MECHANISM WHILE X-RAYS
ARE BEING GENERATED. CHECK THE BEAM POSITION, ADJUST THE POSITION WITH
THE X-RAYS SWITCHED OFF AND THEN RECHECK THE POSITION. IF THE BEAM IS
STILL MISALIGNED REPEAT THE OPERATION.
If the beams are too high or too low loosen the two screws that hold the panoramic primary
slot plate in position and adjust as necessary. Tighten the screws and recheck the beam.
Repeat the above procedure until the beam is correctly positioned.
