IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSEOR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuantto part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercialenvironment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may causeharmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be requiredto correct the interference at their own expense.The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is notinstalled in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found tocomply 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 reasonableprotection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digitaldevices. 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 televisioncommunications at your own expense.You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of itsperipheral 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 interference 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 circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuitscontrolled by different circuit breakers or fuses.)Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.NOTWITHSTANDING ANY OTHER WARRANTY HEREIN, ALL DOCUMENT FILES AND SOFTWARE OF THESE SUPPLIERS ARE PROVIDED “AS IS” WITHALL FAULTS.
