KYOCERA 4550ci Benutzerhandbuch

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.

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.

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.

For safety of the service personnel, follow the maintenance instructions in the other section of this manual.

The power to the laser unit is cut off when the right cover is opened.
