automatic threading when loaded in transport. The spine of the cartridge contains a label listing
the volume identification number.

Class A digital
device
Class A equipment is intended for commercial installation.
Class I laser
product
Class 1 lasers are products where the power of the laser beam produced (the accessible emission)
is always below the Maximum Permissible Exposure value. Therefore, for Class 1 lasers the output
power is below the level at which it is believed eye damage will occur. Exposure to the beam of
a Class 1 laser will not result in eye injury. Class 1 lasers may therefore be considered eye safe.
