lation. If this device does cause harmful interference to radio or television reception, 

which can be determined by turning the device off and on, the user is encouraged to 

try to correct the interference by one or more of the following measures: 

• Reorient or relocate the receiving antenna. 

• Increase the separation between the device and receiver. 

• Connect the device into an outlet on a circuit different from that to 

which the receiver is connected.

• Consult the dealer or an experienced radio/television technician for 

help.
