10. Grounding or Polarization - This video 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 socket
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.

sure the service technician has used replacement parts specified by the
manufacturer or have the same characteristics as the original parts.
Unauthorized substitutes may result in fire, electric shock or other
hazards.
14. Power Lines - An outside antenna system should not be located
in the vicinity of overhead power lines, other electric light or power
circuits, 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
may be fatal.

product, be sure the antenna or cable system is grounded so as to
provide some protection against voltage surges and built-up static
charges.
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 a fire or electric shock.
Never spill liquid of any kind on the product.
a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm (aluminum,
No.7 AWG (10mm ) copper-clad steel or bronze wire or larger, as
ground wire.
17. Servicing - Do not attempt to service this product yourself as
opening or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in
enters house.
18. Damage Requiring Service - Unplug this product from the wall
outlet and refer servicing to qualified service personnel under the
following conditions:
d. A driven rod may be used as the grounding electrode where other
typesofelectrodesystemsdonotexist. RefertotheNationalElectrical
Code, ANSI/NFPA 70-1984 for information.
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the
product.
e. Use jumper wire not smaller than No.6 AWG (13.3mm ) copper or
equivalent, when a separate antenna grounding electrode is used.
c. If the product has been expesed to rain or water.
d. If the product does not operate normally by following
the operating instructions. Adjust only those controls that are covered
by the operating instructions. An improper adjustment may result in
