4 Safety
4.1 Safety of Laser Light
Laser light can prove to be harmful to the human body. The machine’s laser system, how-
ever, is sealed inside a protective housing and external covers to prevent leakage of laser
light to its outside, ensuring the safety of the user as long as the machine is used for its in-
tended functions.
4.2 CDRH Ordinances
The Center for Devices and Radiological Health (CDRH) of the US Food and Drum Ad-
ministration put into force ordinances related to laser products on August 2, 1976.
These ordinances apply to laser products manufactured on and after August 1, 1976, and
sale of laser products is prohibited within the US unless they bear a certificate of compli-
ance.
The following is the label that indicates compliance with the CDRH ordinances, and it
must be found on all laser products sold in the US.

4.3 Handling the Laser System
You must take extra care when servicing the area around the machine’s laser system, as by
not bringing a high-reflectance screwdriver into the laser path.
Take such precautions as removing the watch and rings before starting the work (to pre-
vent reflection of laser light to the eye).
The machine’s laser light is red, and covers that can reflect laser light are identified by the
following label. Take full care whenever servicing areas of the machine behind these covers.
This label is attached to all covers inside the machine where hazards from
laser light exist.
