SAFETY OF LASER BEAM (USA)
1. Safety of laser beam
This machine has been certified by the manufacturer to Class 1 level
under the radiation performance standards established by the
U.S.DHHS (Department of Health and Human Services) in 1968. This
indicates that the product is safe to use during normal operation and
maintenance. The laser optical system, enclosed in a protective housing
and sealed within the external covers, never permits the laser beam to
escape.
2. The CDRH Act
A laser-product-related act was implemented on Aug. 2, 1976, by the
Center for Devices and Radiological Health (CDRH) of the U.S. Food
and Drug Administration (FDA). This act prohibits the sale of laser
products in the U.S. without certification, and applies to laser products
manufactured after Aug. 1, 1976. The label shown below indicates
compliance with the CDRH regulations and must be attached to laser
products marketed in the United States. On this machine, the label is on
the right.
3. Optical unit
When checking the optical unit, avoid direct exposure to the laser beam,
which is invisible. Shown at below is the label located on the cover of the
optical unit.
4. Maintenance
For safety of the service personnel, follow the maintenance instructions
in the other section of this manual.
5. Safety switch
The power to the laser unit is cut off when the front cover is opened.
