sink or laundry tub; in a wet basement; near a swimming
pool; or the like.
8. Accessories. Do not place this product on an unsta-
ble cart, stand, tripod, bracket or table. The product may
fall, causing serious injury to a child or adult, and serious
damage to the product. Use only with a cart, stand, tri-
pod, bracket or table recommended by the manufacturer,
or sold with the product. Any mounting of the product
should follow the manufacturer’s instructions, and should

turer.
9. A Product and Cart Combination
Should Be Moved with Care. Quick
stops, excessive force and uneven surfaces
may cause the product and cart combination to 
overturn.
10. Ventilation. Slots and openings in the cabinet
are provided for ventilation and to ensure reliable
operation of the product and to protect it from over-
heating, and these openings must not be blocked or
covered. The openings should never be blocked by
placing the product on a bed, sofa, rug or other similar
surface. This product should not be placed in a built-in
installation, such as a bookcase or rack, unless proper
ventilation is provided or the manufacturer’s instruc-
tions have been adhered to.
11. Power Sources. This product should be operated
only from the type of power source indicated on the

marking label. If you are not sure of the type of power
supply to your home, consult your product dealer or local
power company. For products intended to operate from
battery power, or other sources, refer to the operating
instructions.
12. Polarization. This product may be equipped with a
polarized alternating-current-line plug (a plug having one
blade wider than the other). This plug will fit into the
power outlet only one way. This is a safety feature. If you
are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, con-
tact your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
13. Power-Cord Protection. Power-supply cords
should be routed so that they are not likely to be walked
on or pinched by items placed upon or against them, pay-
ing particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the 
product.
14. Nonuse Periods. The power cord of the product
should be unplugged from the outlet when left unused for
long periods of time.
15. 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, 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 A.
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 out-
side 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, exten-
sion 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.
20. 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.
21. Damage Requiring Service. Unplug this product
from the wall outlet and refer servicing to qualified 
service personnel under the following conditions:
a. The power-supply cord or the plug has been damaged;
or
b. Objects have fallen onto, or liquid has been spilled
into, the product; or
c. The product has been exposed to rain or water; or
d. The product does not operate normally when follow-
ing the operating instructions. Adjust only those controls
that are covered by the operating instructions, as an
improper adjustment of other controls may result in dam-
age and will often require extensive work by a qualified
technician to restore the product to its normal operation;
or
e. The product has been dropped or damaged in any way;
or
f. 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 replace-
ment parts specified by the manufacturer or that 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 per-
form 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
manufacturer.
