NEC SILENTWRITER SUPERSCRIPT 660 User Manual page 311

LASER SAFETY
This printer is certified as a Class 1 laser product under the U.S. Depart-
ment 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 printer does not produce hazardous laser radia-
tion.
Since radiation emitted inside the printer is completely confined within
protective housings and external covers, the laser beam cannot escape from
the machine during any phase of user operation.
CDRH REGULATIONS
The Center of Devices and Radiological Health (CDRH) of the U.S. Food
and Drug Administration implemented regulations for laser products on
August 2, 1976. These regulations apply to laser products manufactured
from August 1, 1976. Compliance is mandatory for products marketed in
the United States. The printer's rear panel indicates compliance with the
CDRH regulations and must be attached to laser products marketed in the
United States.
Caution: Use of controls, adjustments, or performance of procedures other
than those specified in this manual, may result in hazardous radiation
exposure.
