ZAP-X Radiosurgery System, Model: 300150

Reason: If the radiosurgery system triggers a proximity error message during a long gantry move (greater-than180 degrees), and a subsequent proximity error message occurs after the automatic reduction of speed, a software defect could potentially lead the collimator to collide with patient shoulders or the patient table.
