FCC Statement 
Federal Communication Commission Interference Statement 

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 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. 

 

Consult the dealer or an experienced radio/TV technician for help. 

FCC Caution: Any changes or modifications not expressly approved by the party 
responsible for compliance could void the user

’s authority to operate this equipment.
