xxiii
This machine complies with 21 CFR Chapter 1 Subchapter J as
a Class 1 laser product under the U.S. Department of Health
and Human Services (DHHS) Radiation Performance Standard
according to the Radiation Control for Health and Safety
Act of 1968. This means that the machine does not produce
hazardous radiation.
Since radiation emitted inside the machine is completely
confined within protective housings and external covers, the
laser beam cannot escape from the machine during any phase
of user operation.

U.S. Food and Drug Administration implemented regulations
for laser products on August 2, 1976. These regulations

Compliance is mandatory for products marketed in the United

Use of controls, adjustments, or performance of procedures
