The FCC Wants You To Know 
 
Your receiver might cause radio or TV interference even when it is
operating properly.  To determine whether your receiver is causing the
interference, turn off your receiver.  If the interference goes away, your
receiver is causing it.  Try to eliminate the interference by: 

    Moving your radio or TV away from the receiver. 

    Connecting your receiver to an outlet that is on a different electrical 
    circuit from the radio or TV. 

    Contacting your local Radio Shack store for help. 

If you cannot eliminate the interference, the FCC requires that you stop 
using your receiver.
