Example of the label
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 60825-1 for
Class 1 laser products.
Class 1 laser products are not considered hazardous. The design of the laser
system and the optical storage drive ensures that there is no exposure to laser
radiation above a Class 1 level during normal operation, user maintenance,
or servicing.
When a CD or DVD drive is installed, note the following handling
instructions.
Use of controls, adjustments, or performance of procedures other than those
specified herein might result in hazardous radiation exposure.
