SAFETY AND OPERATION
POWER-CORD PROTECTION: Power supply cords should be routed so that they are not likely to be
walked on or pinched by objects placed upon or against them, paying particular attention to cords at plugs,
convenience receptacles and the point where they exit from the product.
OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is connected to the product,
be sure the antenna or cable system is grounded so as to provide some protection against voltage surges
and built-up static charges. Article 810 of the National Electric Code, ANSI/NFPA 70, provides information
with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to
grounding electrodes and requirements for the grounding electrode. See Figure B
OVERLOADING: Do not overload wall outlets, extension cords or integral convenience receptacles as this
can result in a risk of fire or electric shock.
OBJECT AND LIQUID ENTRY: Never push objects of any kind into this product through openings as they
may touch dangerous voltage points
or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the product.
SERVICING: Do not attempt to service this product yourself as opening or removing covers may expose
