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.
Exception: A product that is meant for uninterrupted service and that for
some specific reason, such as the possibility of the loss of an authorization
code for a CATV Converter, is not intended to be unplugged by the user for
cleaning or any other purpose, may exclude the reference to unplugging the
product in the cleaning description otherwise required in number 5.

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, washbowl, 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 stop, 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) 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 for grounding conductors, location of antenna-discharge unit,
connection to grounding electrodes, and requirements for the grounding
electrode. See Figure A.

15) 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.

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, extension cords, or integral
convenience receptacles 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) When 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 damaged in any way.
f) When the product exhibits a distinct change in performance – this
indicates a need for service.

21) 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.

22) 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.

23) Wall or Ceiling Mounting – The product should be mounted to a wall
or ceiling only as recommended by the manufacturer.
