Laser Safety Information

The optical drive in this system unit is a laser product. The optical drive has a label that identifies 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 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 laser products.
CAUTION:
A class 1 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
replaced as a unit.
C07
Class 1 laser products are not considered to be hazardous. The optical drive contains internally a Class
3B gallium-arsenide laser that is nominally 30 milliwatts at 830 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.
