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 protection against voltage surges and
built-up static charges. Article 810 of the National Electrical
Code (U.S.A.), 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 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 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.

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

Unplug this product from the wall outlet and refer servicing to
qualified service personnel under the following conditions:

a. If 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 instructions. Adjust only those controls that are

covered by the operating 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.
