General Warnings and Cautions
3. Power-cord protection. Power-supply
cords should be routed so that they are
not likely to be walked on or pinched by
items placed upon or against them, paying
particular attention to cords at plugs,
convenience receptacles, and the point
where they exit from the product.
4. 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 Electrical 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.
5. Lightning. For added protection for this
product during a lightning storm, or when
it is left unattended and unused for long
periods of time, unplug it from the wall
outlet and disconnect the antenna or cable
system. This will prevent damage to the
product due to lightning and power-line
surges.
6. Power lines. An outside antenna system
should not be located in the vicinity of
overhead power lines or other electric
light or power circuits, or where it can fall
into such power lines or circuits. When
installing an outside antenna system
extreme care should be taken to keep from
touching such power lines or circuits as
contact with them might be fatal.
7. Overloading. Do not overload wall outlets,
extension cords, or integral convenience
receptacles as this can result in a risk of
fire or electric shock.
8. 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.
