15. Outdoor Antenna Grounding - If an outside antenna is connected to the receiver, be sure the antenna system
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 electrode. See figure:
16. 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 lightning and power-line surges.
17. 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.
18. Overloading - Do not overload wall outlets, extension cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.
19. 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.

dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
21. 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 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 damaged in any way, and
f ) When the product exhibits a distinct change in performance - this indicates a need for service.
22. 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.
23. 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.
24. Wall or Ceiling Mounting - The product should be mounted to a wall or ceiling only as recommended by the
