8. Ventilation – Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the
product and to protect it from overheating, and these openings must not be blocked or covered. The openings should
never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should not be placed
in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s
instructions have been adhered to.
9. Power Sources – This product should be operated only from the type of power source indicated on the marking label.
If you are not sure of the type of power supply to your home, consult your product dealer or local power company. For
products intended to operate from battery power, or other sources, refer to the operating instructions.
10. Grounding and Polarization – This product may be equipped with a polarized alternating-current line plug (a plug having
one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
11. 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.
12. 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 the 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.
13. 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 systems. This will prevent
damage to the product due to lightning and power-line surges.
14. 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.
15. Overloading – Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in
a risk of fire or electric shock.
