Laser Information
Warning Making adjustments or performing procedures other than those specified in your equipment’s
manual may result in hazardous radiation exposure.
Do not attempt to disassemble the cabinet containing the laser. The laser beam used in this product is harmful to
the eyes. The use of optical instruments, such as magnifying lenses, with this product increases the potential
hazard to your eyes. For your safety, have this equipment serviced only by an Apple-authorized service provider.
If you have an internal Apple CD-ROM, DVD-ROM, or DVD-RAM drive in your computer, your computer is a Class
1 laser product. The Class 1 label, located in a user-accessible area, indicates that the drive meets minimum safety
requirements. A service warning label is located in a service-accessible area. The labels on your product may differ
slightly from the ones shown here.
