installation. If this equipment does cause harmful
interference to radio or television reception, which
can be determined by turning the equipment 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 equipment
and 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.
