Operator Safety:
This machine is considered a CDRH class I laser device, safe for office/EDP use. The machine con-
tains 7 milliwatt, 645 - 660 nanometer wavelength, AlGaInp Laser Diode. Direct (or indirect reflected)
eye contact with the laser beam might cause serious eye damage. Safety precautions and interlock
mechanisms have been designed to prevent any possible laser beam exposure to the operator.
Laser Safety:
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical unit
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 or the optical subsystem is re-
quired.
