Class B Notice for FCC

Modifying the equipment without Cisco’s authorization may result in the equipment no longer
complying with FCC requirements for Class B digital devices. In that event, your right to use the
equipment may be limited by FCC regulations, and you may be required to correct any interference to
radio or television communications at your own expense.
This equipment has been tested and found to comply with the limits for a Class B digital device,

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, 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, 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 receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
