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.
