14. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product, be
sure the antenna or cable system is grounded so as to provide some pro-
tection against voltage surges and built-up static charges. Article 810 of
the National Electrical Code (U.S.A.), ANSI/ NFPA 70 provides informa-
tion with regard to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of ground-
ing conductors, location of antenna-discharge unit, connection to ground-
ing electrodes, and requirements for the grounding electrode.
15. Lightning
For added protection for this product (receiver) 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 lightning and power-line
surges.
16. Power Lines
An outside antenna system should not be located in the vicinity of over-
head 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.
17. Overloading
Do not overload wall outlets and extension cords as this can result in a
risk of fire or electric shock.
18. 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.
19. 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.
20. Damage Requiring Service

ating instructions as an improper adjustment of other controls 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.
f. If the product exhibits a distinct change in performance.
21. Replacement Parts
When replacement parts are required, be sure the service technician has
used replacement parts specified by the manufacturer or have the same
characteristics as the original part. Unauthorized substitutions may result
in fire, electric shock, or other hazards.
22. Safety Check
Upon completion of any service or repairs to this product, ask the service
technician to perform safety checks to determine that the product is in
proper operating condition.
23. Wall or Ceiling Mounting
