and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular 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 distance 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.
