Laser Safety
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based
optical units in the field. The optical housing unit can only be repaired in a factory or at a
location with the requisite equipment. The laser subsystem is replaceable in the field by a
qualified Customer Engineer. The laser chassis is not repairable in the field. Customer
engineers are therefore directed to return all chassis and laser subsystems to the factory or
service depot when replacement of the optical subsystem is required.
 Use of controls, or adjustment, or performance of procedures other than those
specified in this manual may result in hazardous radiation exposure.
 WARNING: Turn off the main switch before attempting any of the procedures in the
Laser Optics Housing Unit section. Laser beams can seriously damage your eyes.
 CAUTION MARKING:
