Emissions Regulations

Federal Communications Commission (FCC)

The Federal Communications Commission of the U.S. government regulates the
radio frequency energy emanated by computing devices through pubhshed 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 comply with these limits. The FCC regulations also require that com­putin~ devices used in the U.S. display the agency’s label and that the related docu­ment~tion include the following statement:

WARNING:

Compliance to these regulations requires the use of shielded cables.

Canadian Department of Communications (DOC)

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 interference when the equipment is
operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency enerb~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.

This digital apparatus does not exceed the Class A limits for radio noise emissions
from d;gital apparatus as set out in the Radio Interference Requirements of the
Canadian Department of Communications.

Compliance to these regulations requires the use of shielded cables.

Emissions Regulations Compliance

Electrostatic Discharge (ESD) Precautions

Electrostatic charges can damage the integrated circuits on printed circuit boards.

TO prevent such damage from ckxming, &bservethe following precautions when

unpacking and installing the board.

● Stand on a static–free mat.

● Wear a static strap to ensure that any accumulated electrostatic charge dis-

charges from your body to ground.

● Connect all equipment together, including the static–free mat, static straps,

routing nodes, and peripheral units.

. Keep uninstalled printed circuit boards in their protective antistaticbags.

● Once you have removed the printed circuit boards from their protective an-

tistatic bags, handle them by their edges.
