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  or  television 
technician for help.
