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.
• Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams
can seriously damage your eyes.
Caution Labels
Caution labels are provided on the machine that warn service personnel and operators about how to avoid
exposure to levels of laser and collateral radiation known to be hazardous.
Lithium Batteries (Memory Back-up)
• The danger of explosion exists if a battery of this type is incorrectly replaced. Replace only with the
same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance
with the manufacturer’s instructions.
