13. 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.
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.
