Emissions Regulations
Federal Communications Commission (FCC)
The Federal Communications Commission of the U.S. government regulates the ra-
dio frequency energy emanated by computing devices through published regulations.
These regulations specify the limits of radio frequency emission to protect radio and
television reception. All HP Apollo nodes and peripherals have been tested and com-
ply with these limits. The FCC regulations also require that computing devices used
in the U.S. display the agency’s label and that the related documentation include the
following statement:
NOTICE: This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful in-
terference when the equipment is operated in a com-
mercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area is likely to cause harmful interference
in which case the user will be required to correct the
interference at his own expense.
Compliance to these regulations requires the use of shielded cables.
Canadian Department of Communications (DOC)
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus as set out in the Radio Interference Requirements of the Cana-
dian Department of Communications.
Compliance to these regulations requires the use of shielded cables.

VCCI Class 1 ITE
Emissions Regulations Compliance
Any third–party I/O device installed in HP Apollo system(s) must be in accordance
with the requirements set forth in the preceding Emissions Regulations statements. In
the event that a third–party noncompliant I/O device is installed, the customer as-
sumes all responsibility and liability arising therefrom.
Compliance to these regulations requires the use of shielded cables.
Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit boards. To
prevent such damage from occurring, observe the following precautions when un-
packing and installing the board.
DStand on a static–free mat.
DWear a static strap to ensure that any accumulated electrostatic charge dis-
charges from your body to ground.
DConnect all equipment together, including the static–free mat, static straps,
routing nodes, and peripheral units.
DKeep uninstalled printed circuit boards in their protective antistatic bags.
DOnce you have removed the printed circuit boards from their protective antis-
tatic bags, handle them by their edges.

Laser Safety Statement (For U.S.A. Only)
(For workstations that have a CD–ROM 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.
