Federal Communications Commission (FCC) Statement

This equipment has been tested and found to comply with the limits for a Class B digital

device, pursuant to Part 15 of 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 instructions contained in this manual, 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
