Laser Safety InformationThe optical drive in this system unit is a laser product. The optical drive has a label thatidentifies its classification. The label, located on the drive, is shown below.The optical drive in this system unit is certified in the U.S. to conform to therequirements of the Department of Health and Human Services 21 Code of FederalRegulations (DHHS 21 CFR) Subchapter J for Class 1 laser products. Elsewhere, thedrive is certified to conform to the requirements of the International ElectrotechnicalCommission (IEC) 825 (1st edition 1984) and CENELEC EN 60 825:1991 for Class 1laser products.CAUTION:A class 3 laser is contained in the device. Do not attempt to operate the drivewhile it is disassembled. Do not attempt to open the covers of the drive as it isnot serviceable and is to be replaced as a unit.Class 1 laser products are not considered to be hazardous. The optical drive containsinternally a Class 3B gallium-arsenide laser that is nominally 0.14 milliwatts at 765 to815 nanometers. The design incorporates a combination of enclosures, electronics, andredundant interlocks such that there is no exposure to laser radiation above a Class 1level during normal operation, user maintenance, or servicing conditions.CLASS 1 LASER PRODUCTLASER KLASSE 1LUOKAN 1 LASERLAITEAPPAREIL A LASER DE CLASSE 1IEC 825:1984 CENELEC EN 60 825:1991Preface xiii
