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. 

Any changes or modifications not expressly approved by the manufacturers may void the user's authority to 
operate this equipment. 

Note:

 A shielded-type Video cord is required in order to meet the FCC emission limits and also to prevent 

interference to the radio and television reception. It is essential that only the supplied Video cord be used.
