Special Video Configuration Statements
iv
Special Video Configuration Statements
The following statements apply only to those applica-
tions which include a cable connected to the S-Video
connector on the A4248A card. No modification to the
regulatory statements is necessary for applications
which include cables connected to other connectors on
the card but not to the S-Video connector.
For EN55022 or CISPR 22 Applications:
WARNING: This is a Class A product. In a domestic environment
this product may cause radio interference in which
case the user may be required to take adequate
measures.
For FCC Applications:
NOTICE: This equipm,ent 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 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.

Emissions Regulations
Federal Communications Commission (FCC)
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules and the Canadian Depart-
ment of Communications. These limits are designed to
provide reasonable protection against harmful interfer-
ence in a residential installation. This equipment gen-
erates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to
radio or television reception (determined by turning
the equipment off and on), you can correct the interfer-
ence by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit differ-
ent from that to which the receiver is connected.
• Ask the dealer or an experienced radio/television techni-
cian for help.
Hewlett-Packard’s system certification tests were con-
ducted with HP-supported peripheral devices and HP
shielded cables, such as those you receive with your
computer. Changes or modifications not expressly
approved by Hewlett-Packard could void the user’s
authority to operate the equipment.

Electrostatic Discharge (ESD)
Precautions
Electrostatic charges can damage the integrated cir-
cuits on printed circuit boards. To prevent such dam-
age 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 elec-
trostatic charge is discharged from your body to ground.
• Connect all equipment together, including the static-free
mat, static strap, routing nodes, and peripheral units.
• Keepuninstalledprintedcircuitboardsintheirprotective
antistatic bags.
• Handle printed circuit boards by their edges, once you
have removed them from their protective antistatic bags.
Safety Statement
This equipment conforms to the following safety stan-
dards:
• UL 1950
• CSA 950
• IEC 950
• EN 60950

Laser Safety Statement (U.S.A. Only)
ix
Laser Safety Statement (U.S.A. Only)
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 Per-
formance Standard according to the Radiation Control
for Health and Safety Act of 1968.
This means that the mass-storage system does not pro-
duce hazardous laser radiation. Because laser light
emitted inside the mass-storage system is completely
confined within protective housings and external cov-
ers, the laser beam cannot escape from the machine
during any phase of user operation.
