operate from battery power, or other sources, refer to the operating instructions.
11. 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.
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 product 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 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 and extension cords as this can result in a risk of fire or
electric shock.
16. OBJECT AND LiQUiD ENTRY
Never push objects of any kind into this product through openings as they may touch
dangerous voltage points or short out parts that could result in fire or electric shock.
17.
Never spill or spray any type
of liquid on the product.
