ƒ To prevent a fire or explosion, keep the machine away from flammable liquids,
gases, and aerosols. A fire or an explosion might occur.
ƒ
The Controller board on the MF model contains a lithium battery. 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 batteries in
accordance with the manufacturer's instructions and local regulations.
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.
ƒ Use of controls, or adjustment, or performance of procedures other than those
specified in this manual may result in hazardous radiation exposure.
WARNING
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.
