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 full 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.
11. Power Sources - This product should be operated only
from the type of power source indicated on the marking label.
If you are not sure of the type of power supplied to your home,
consult your appliance dealer or local power company.
12. Power-cord Protection - Power-supply cords should be
routed so they are not likely to be walked on or pinched by
items placed upon or against them. Pay particular attention to
cords and plugs, convenience receptacles, and the point
where they exit from the appliance.
13. 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.
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.
15. Overloading - Do not overload wall outlets and extension
cords as this can result in 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 danger-
ous voltage points or short-out parts that could result in a fire
or electric shock. Never spill liquid of any kind on the product.
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.
18. Damage Requiring Service - Unplug this product 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
product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following the
operating instruction. Adjust only those controls that are

ment may result in damage and will often require extensive
work by a qualified technician to restore the product to its
normal operation.
e. If the product has been dropped or the cabinet has been
damaged.

grounded so as to provide some protection against voltage
surges and built-up static charges.
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.
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.
d. A driven rod may be used as the grounding electrode where
other types of electrode systems do not exist. Refer to the
National Electrical Code, ANSI/NFPA 70-1984 for information.
e. Use jumper wire not smaller than No.6 AWG (13.3mm )
copper or equivalent, when a separate antenna grounding
electrode is used.
