IMPORTANT SAFETY INSTRUCTIONS
(Continued from previous page)
14. Outdoor Antenna Grounding
If an outside antenna or cable system is con-
nected 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 unat-
tended 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 per-
form safety checks to determine that the product
is in proper operating condition.
23. Wall or Ceiling Mounting

damage to the product.
24. Heat
The product should be situated away from heat
sources such as radiators, heat registers,
stoves, or other products (including amplifiers)
that produce heat.
