IMPORTANT SAFETY INSTRUCTIONS
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 dis-
charge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding elec-
trode.
15. Lightning
For added protection for this product (receiver) dur-
ing 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 volt-
age 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 dan-
gerous voltage or other hazards. Refer all servicing to
qualified service personnel.
20. Damage Requiring Service
Unplug this product from the wall outlet and refer ser-
vicing to qualified service personnel under the fol-
lowing 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 perfor-
mance.
21. Replacement Parts
When replacement parts are required, be sure the
service technician has used replacement parts spec-
ified by the manufacturer or have the same charac-
teristics as the original part. Unauthorized substitu-
tions may result in fire, electric shock, or other haz-
ards.
