DVD drive. CD and DVD drives are also sold separately as options. CD and DVD
drives are laser products. These drives are 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,
these drives are certified to conform to the requirements of the International
Electrotechnical Commission (IEC) 60825-1 and CENELEC EN 60 825-1 for Class
1 laser products.
When a CD or DVD drive is installed, note the following handling instructions.
