Some models of ThinkPad Notebook are equipped from the factory with an optical
storage device such as a CD-ROM drive or a DVD-ROM drive. Such devices are
also sold separately as options. If one of these drives is installed, it 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) 60825-1 and CENELEC EN
60825-1 for Class 1 laser products.
If a CD-ROM drive, a DVD-ROM drive, or another laser device is installed, note
the following:

specified herein might result in hazardous radiation exposure.
Opening the CD-ROM drive, the DVD-ROM drive, or any other optical storage
device could result in exposure to hazardous laser radiation. There are no
