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 FOR LASER UNIT

Turn off the main switch before attempting any of the procedures in the Laser Unit
