INFORMATIONFORTHEUSER

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.

EMC: This card has been tested and found to comply with the following standards:

· International: CISPR22 Class B.

· Europe: EMC 89/336/CEE (1992) specifications.

· United States: FCC Rules-Part 15-Class B (digital device).

In order to guarantee compliance with the above standards in an installation, the

following must be done:

· Connectors must have a conductive shell.

· Cables must be shielded and their shield must be tightly connected to the

shell of the connectors.

· A good contact must exist between the bracket and the PC frame.
