be placed in a built-in installation such as a bookcase
or rack unless proper ventilation is provided or the

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.
12 Grounding or Polarization
This product is 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.
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 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 volt-
age 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, ground-
ing of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of antenna-dis-
charge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
