The optical drive in this system unit is certified in the U.S. to conform to the
requirements of the Department of Health and Human Services 21 Code of Federal
Regulations (DHHS 21 CFR) Subchapter J for Class 1 laser products. Elsewhere, the
drive is certified to conform to the requirements of the International Electrotechnical
Commission (IEC) 825 (1st edition 1984) and CENELEC EN 60 825:1991 for Class 1

CAUTION:
A class 3 laser is contained in the device. Do not attempt to operate the drive
while it is disassembled. Do not attempt to open the covers of the drive as it is
not serviceable and is to be replaced as a unit.
Class 1 laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium–arsenide laser that is nominally 0.14 milliwatts at 765 to
815 nanometers. The design incorporates a combination of enclosures, electronics, and
redundant interlocks such that there is no exposure to laser radiation above a Class 1
level during normal operation, user maintenance, or servicing conditions.
