Important safety Instructions
22
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. 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 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 onto or against 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 to provide some protection against voltage surges and built-up static
charges, Section 810 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.
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.
