pool; or the like.
8. Accessories. Do not place this product on an unstable
cart, stand, tripod, bracket or table. The product may fall,
causing serious injury to a child or adult, and serious dam-
age to the product. Use only with a cart, stand, tripod,
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 use a mounting
accessory recommended by the manufacturer.
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 pro-
vided for ventilation and to ensure reliable operation of the
product and to protect it from overheating, and these open-
ings 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, contact your electrician to
replace your obsolete outlet. Do not defeat the safety pur-
pose 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, paying 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 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.
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 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; 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 substi-
tutions 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
manufacturer.
25. Heat. The product should be situated away from heat
sources such as radiators, heat registers, stoves or other
products (including amplifiers) that produce heat.
