dealer or local power company. For products intended to operate
from battery power, or other sources, refer to the operating instruc-
tions.
12. Grounding or Polarization - This product may be 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.
Alternate Warnings - This product is equipped with a three-wire
grounding-type plug, a plug having a third(grounding) pin. This plug

convenience receptacles, and the point where they exit from the
product.
14. Outdoor Antenna Grounding - If an outside antenna or cable sys-
tem is connected to the product, be sure the antenna or cable sys-
tem is grounded so as to provide some protection against voltage
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, 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 elec-
trode. See Figure 1.

15. Lightning - For added protection for this product during 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 light-
ning and power-line surges.
16. 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.
