1 INFORMATION FOR THE USER

This device complies with part 15 of FCC rules. Operation is subject to the

following two conditions: (1) This device may not cause harmful interference,

and (2) This device must accept any interference received, including

interference that may cause undesired operation.

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. These limits are

designed to provide reasonable protection against harmful interference in a

residential installation. This equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in accordance with the

instructions contained in this data sheet, may cause harmful interference to

radio and television 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, which can be determined by turning the equipment off and on, the

user is encouraged to try to correct the interference 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 different from that of the

receiver

* consult the dealer or an experienced audio television technician.

Note



: Connecting this device to peripheral devices that do not comply with

CLASS B requirements or using an unshielded peripheral data cable could also

result in harmful interference to radio or television reception. The user is

cautioned that any changes or modifications not expressly approved

by the party responsible for compliance could void the user’s

authority to operate this equipment. To ensure that the use of this product

does not contribute to interference, it is necessary to use shielded I/O

cables.

Warning:

Electrostatic discharge (ESD) can damage

several components on the board. To avoid

such damage in handling the board, take the

following precautions:

Bring the device and everything that contacts it

to ground potential by providing a conductive

surface and discharge paths. As a minimum, observe these precautions:

●Disconnect all power and signal sources.

●Place the device on a grounded conductive work surface.



●Ground yourself via a grounding wrist strap or

by holding a grounded object.

●Ground any tool that will contact the device.

Due to the reduced length of the PCI EXPRESS



TM bus connector

and the resulting lack of mechanical stability, we strongly advise

against transporting the card(s) installed in a computer, unless its

chassis or case provides a dedicated support to keep the card

securely in place in order to avoid physical damage.
