The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may rad iate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment wit hou t Cisco’s written autho riz atio n may resul t in the equi pme nt no longe r comply ing with FCC re quir ements for Class A or Class B digital devices. In that event, your right to use the equipment m ay be lim ited by FCC regulati ons, and yo u may be r equired to correct any interference to radio or television communicati ons at your own expense.

You can determine whether your equipment is causing int erferen ce by turning it off. If the inter ference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interferenc e stops.

• Move the equipment to one side or the other of the television or radio .

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circ uit from the tel evision or radio. (That is, make certain the equip ment and the television or radio are on circuits controlled by different circui t breakers or fuses.)
