This equipment has been tested and found to comply with the limits for a Class B digi tal 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 eq uipment generates uses and can radiate radio frequency energy and, if not installed an d used in accordance with the instructions, may cause harmful interference to radio co mmunications. However, there is no guarantee that interference will not occur in a par ticular installation. If this equipment does cause harmful interference to radio or televi sion 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 measu res:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the r eceiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the 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
