laser safety statement (U.S.A.)
(For workstations that have a CD drive installed.)
The CD-ROM mass-storage system is certified 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 mass-storage system does not produce hazardous laser radiation.
Because laser light emitted inside the mass-storage system is completely confined within
protective housings and external covers, the laser beam cannot escape from the machine
during any phase of user operation.
LEDs
The LEDs on this product are classified as “Class 1 LED PRODUCT” in accordance with
EN 60825-1.
electrostatic discharge (ESD) precautions
Electrostatic charges can damage the integrated circuits on printed circuits boards. To
prevent such damage from occurring, observe the following precautions during board
unpacking and installation:
Stand on a static-free mat.
Wear a static strap to ensure that any accumulated electrostatic charge is discharged
from your body to ground.
Connect all equipment together, including the static-free mat, static strap, routing
nodes, and peripheral units.
Keep uninstalled printed circuit boards in their protective antistatic bags.
Handle printed circuit boards by their edges, once you have removed them from their
protective antistatic bags.
