The drive is certified by the manufacturer to comply with the requirements of the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21 CFR) Subchapter J for Class I laser products at the date of manufacture. In other countries, the drive is certified to conform to the requirements of IEC825 and EN60825 for Class 1 laser products. DANGER Do not open the optical storage drive unit; no user adjustments or serviceable parts are inside. Use of controls, adjustments, or the performance of procedures other than those specified might result in hazardous radiation exposure. 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. Some drives contain an embedded Class 3A laser diode. Note this warning: DANGER Emits visible and invisible laser radiation when open. Avoid direct eye exposure. Do not stare into the beam or view it directly with optical instruments. DANGER Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. xii ThinkPad® G40 Series Service and Troubleshooting Guide
