RADIO AND TELEVISION INTERFERENCE 

 
This equipment has been tested and found to comply with the limits for a Class B digital 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 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 the receiver. 
- Connect the equipment into an outlet on a circuit different from that to which the receiver is 
connected. 
- Consult the dealer or an experienced radio/TV technician for help. 
 
 

You may also find helpful the following booklet, prepared by the FCC: "How to Identify 

and Resolve Radio-TV Interference Problems."  This booklet is available from the U.S. 
Government Printing Office, Washington D.C. 20402. 
 

In order to maintain compliance with FCC regulations shielded cables must be used with 

this equipment.  Operation with non-approved equipment or unshielded cables is likely to result 
in interference to radio & television reception.
