Installation
Installation
Power Sources: This video product should be operated only
from the type of power source indicated on the marking la-
bel. If you are not sure of the type of power supply to your
home, consult your appliance dealer or local power com-
pany. For video products intended to operate from battery
power, or other sources, refer to the operating instructions.
Grounding or Polarization: This video product is equipped
with a polarized alternating-current line plug (a plug having
one blade wider than the other). This plug will fi t 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 fi t, contact your electri-
cian to replace your obsolete outlet. Do not defeat the safety
purpose of the polarized plug.
Alternate Warnings: This video product is equipped with
a three-wire grounding-type plug, a plug having a third
(grounding) pin. This plug will only fi t into a grounding-type
power outlet. This is a safety feature. If you are unable to
insert the plug into the outlet, contact your electrician to re-
place your obsolete outlet. Do not defeat the safety purpose
of the grounding type plug.
Overloading: Do not overload wall outlets and extension
cords as this can result in a risk of fi re or electric shock.
Ventilation: Slots and openings in the cabinet are provided
for ventilation, to ensure reliable operation of the video prod-
uct and to protect it from overheating, and these openings
must not be blocked or covered. The openings should never
be blocked by placing the video product on a bed, sofa, rug,
or other similar surface.
This video product should not be placed in a built-in instal-
lation such as a bookcase or rack unless proper ventilation is
provided or the manufacturer’s instructions have been ad-
hered to. This video product should never be placed near or
over a radiator or heat register.
Attachments: Do not use attachments not recommended by
the video product manufacturer as they may cause hazards.
Water and Moisture: Do not use this video product near wa-
ter—for example, near a bath tub, wash bowl, kitchen sink,
or laundry tub, in a wet basement, or near a swimming pool,
and the like.
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 atten-
tion to cords at plugs, convenience receptacles, and the point
where they exit from the appliance.
Accessories: Do not place this video product on an unstable
cart, stand, tripod, bracket, or table. The video product may
fall, causing serious injury to a child or adult, and serious
damage to the appliance. Use only with a cart, stand, tripod,
bracket, or table recommended by the manufacturer, or sold
with the video product. Any mounting of the appliance
should follow the manufacturer’s instructions, and should use
a mounting accessory recommended by the manufacturer.
An appliance and cart combination
should be moved with care. Quick
stops, excessive force, and uneven
surfaces may cause the appliance and
cart combination to overturn.

Outdoor Antenna Grounding: If an outside antenna or cable
system is connected to the video product, be sure the an-
tenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges.
Section 810 of the National Electrical Code, ANSI/NFPA No.
70, provides information with respect to proper grounding of
the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding con-
ductors, location of antenna discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode.
