Operator Safety This machine is considered a CDRH class I laser device, safe for office/EDP use. The machine contains a 5- milliwatt, 760- 800 nanometer wavelength, GaAIAs 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 required. Warning: Use of controls or adjustment or performance of procedures other than those specified in this manual might result in hazardous radiation exposure.
