IMPORTANT SAFEGUARDS (CONTINUED)
9. VENTILATION
Slots and openings in the cabinet and in the back or bottom are provided for ventilation and to
ensure reliable operation of the unit and to protect it from overheating. These openings must not be
blocked or covered. The openings should never be blocked by placing the unit on a bed, sofa, rug,
or other similar surface. This unit should never be placed near or over a radiator or heat source. This
unit should not be placed in a built-in installation such as a bookcase or rack unless proper ventila-
tion is provided or the manufacturer's instructions have been adheared to.
10. POWER SOURCES
This unit should be operated only from the type of power source indicated on the rating plate. If you
are not sure of the type of power supply to your home, consult your appliance dealer or local power
company. For units intended to operate from battery power, or other sources, refer to the operating
instructions.
11. GROUNDING OR POLARIZATION
This unit 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. If your unit is equipped with a 3-wire grounding-type plug, having a third (grounding)
pin, this plug will only fit into a grounding-type power outlet. This too is a safety feature. Do not
defeat the safety purpose of the grounding-type plug.
12. 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 appliance.
13. LIGHTNING
To protect your unit from 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 unit 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 and extension cords as this can result in a risk of fire or electric shock.
16. OBJECT AND LIQUID ENTRY
Do not push objects through any openings in this unit as they may touch dangerous voltage points
or short out parts that could result in fire or electric shock. Never spill or spray any type of liquid into
the unit.
17. OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system
is grounded so as to provide some protection against voltage surges and built-up static charges.
Section 810 of the National Electric Code, ANSI/NEPA 70, provides information with respect to prop-
er grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna dis-
charge unit, size of grounding conductors, location of antenna discharge unit, connection to ground-
ing electrodes, and requirements for grounding electrode.
