tions should be followed.
5) Cleaning – Unplug this product from the wall out-
let 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 recom-
mended 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, tri-
pod, bracket, or table recom-
mended 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 manufac-
turer.
9) A Product and Cart Combination Should Be
Moved With Care – Quick stop, excessive force, and
uneven surfaces may cause the product and cart com-
bination to overturn.
10) Ventilation – Slots and openings in the cabinet are
provided for ventilation and to ensure reliable opera-
tion 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 instal-
lation such as a bookcase or rack unless proper ventila-
tion 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 oper-
ating instructions.
12) Grounding or Polarization –
This product may be equipped
with a polarized alternating-cur-
rent-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 fea-
ture. 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 obso-
lete 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 sup-
porting 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 sys-
tem. 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 cir-
cuits as contact with them might be fatal.
17) 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.
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 servic-
ing to qualified service personnel.
