14 Protective Attachment Plug – The product is equipped with an attachment plug
having overload protection. This is a safety feature. See Instruction Manual for
replacement or resetting of protective device. If replacement of the plug is
required, be sure the service technician has used a replacement plug specified by
the manufacturer that has the same overload protection as the original plug.
15 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.
16 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.
17 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.
18 Overloading – Do not overload wall outlets, extension cords, or integral
convenience receptacles as this can result in a risk of fire or electric shock.
19 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.
