protection against harmful interference in
a residential installation. This equipment
generates uses and can radiate radio
frequency energy and, if not installed 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

correct the interference by one of the
following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between
the equipment and receiver.
