11.GROUNDING OR POLARIZATION
This unit is equipped with a polarized altemating-current line plug (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, Instead of the polarized alternating-current
line plug, your unit may be equipped with a 3-wire grounding-type plug (a plug having a third
grounding) pin). This plug will only fit into a grounding-type power outlet. This too, is a safety
feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your
obsolete outlet. 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 ling 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 onto or against such power lies 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 to provide some protection against voltage surges and built-up static charges, Section
8 10 of the National Electrical Code (NEC), ANSI/NFPA 70, provides information with respect 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. See figure below.
18. SERVICING
Do not attempt to service this unit yourself as opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
19. DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the unit.
