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.
4. Follow Instructions. All operating and
use instructions should be followed.
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; near a swimming
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 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
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 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.
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.

CAUTION: To prevent electric shock,

 do not remove the grounding plug 

on the power cord, or use any plug 

or extension cord that does not have 

a grounding plug provided. 

Make certain that the 

AC outlet is properly grounded. 

Do not use an adapter plug 

with this product.

The lightning flash with arrowhead symbol, 
within an equilateral triangle, is intended to 
alert the user to the presence of uninsulated 
“dangerous voltage” within the product’s 

enclosure that may be of sufficient magnitude to constitute a 
risk of electric shock to persons.

The exclamation point within an equilateral 
triangle is intended to alert the user to the 
presence of important operating and 
maintenance (servicing) instructions in the 

literature accompanying the appliance.
