interference will not occur in a particular 
installation. If this equipment does 
cause harmful interference to radio

correct the interference by one or more 
of the following measures:
 Reorient or relocate the receiving 
antenna.

on a circuit different from that to 
which the receiver is connected.
 Consult the dealer or an experienced 
radio/TV technician for help.
