1. Read Instructions. All the safety and
operating instructions should be read before
the product is operated.
2. Retain Instructions. The safety and
operating instructions should be retained for
future reference.
3. Heed Warnings. All warnings on the
product and in the operating instructions
should be adhered to.

5. Cleaning. Unplug this product from the
wall outlet before cleaning. Do not use
liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.
6. Attachments. Do not use attachments
not recommended by the product manufacturer, as they may cause hazards.
7. Water and Moisture. Do not use this
product near water – for example, near a
bathtub, wash bowl, kitchen sink or laundry
tub; in a wet basement; or near a swimming
pool; and 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 damage 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 provided for ventilation and to
ensure reliable operation of the product and
to protect it from overheating, 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
instructions 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. Grounding or 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 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, 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 out-
side 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 builtup 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 1.
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.

Grounding as per National
Electrical Code, ANSI/NFPA 70

lets, 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.

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 replacement 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 perform safety checks
to determine that the product is in proper
operating condition.
