NOTE TO CABLE/TV INSTALLER
This reminder is provided to call the CATV system
installer’s attention to Article 820-40 of the National
Electric Code (U.S.A.). The code provides guidelines for
proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system
of the building, as close to the point of the cable entry
as practical.

Never touch this apparatus or antenna during a
thunder or lighting storm.
When mounting a TV on the wall, make sure not to
install the TV by the hanging power and signal
cables on the back of the TV.
Do not allow an impact shock or any objects to fall
into the product, and do not drop onto the screen
with something.
CAUTION concerning the Power Cord :
It is recommend that appliances be placed upon a
dedicated circuit; that is, a single outlet circuit which
powers only that appliance and has no additional
outlets or branch circuits. Check the specification
page of this owner's manual to be certain.
Do not connect too many appliances to the same
AC power outlet as this could result in fire or elec-
tric shock.
Do not overload wall outlets. Overloaded wall out-
lets, loose or damaged wall outlets, extension cords,
frayed power cords, or damaged or cracked wire
insulation are dangerous. Any of these conditions
could result in electric shock or fire. Periodically
examine the cord of your appliance, and if its
appearance indicates damage or deterioration,
unplug it, discontinue use of the appliance, and
have the cord replaced with an exact replacement
part by an authorized servicer. Protect the power
cord from physical or mechanical abuse, such as
being twisted, kinked, pinched, closed in a door, or
walked upon. Pay particular attention to plugs, wall
outlets, and the point where the cord exits the
appliance.
Do not make the TV with the power cord plugged
in. Do not use a damaged or loose power cord. Be
sure do grasp the plug when unplugging the power
cord. Do not pull on the power cord to unplug the
TV.
WA NING - To reduce the risk of fire or electrical
shock, do not expose this product to rain, moisture
or other liquids. Do not touch the TV with wet
hands. Do not install this product near flammable
objects such as gasoline or candles or expose the
TV to direct air conditioning.
Do not expose to dripping or splashing and do not
place objects filled with liquids, such as vases, cups,
etc. on or over the apparatus (e.g. on shelves above
the unit).
GGOOUUNNDDIINNGG
Ensure that you connect the earth ground wire to
prevent possible electric shock. (i.e. a TV with a
three-prong grounded AC plug must be connected
to a three-prong grouned AC outlet) If grounding
methods are not possible, have a qualified electri-
cian install a separate circuit breaker.
Do not try to ground the unit by connecting it to
telephone wires, lightening rods, or gas pipes.
DDIISSCCOONNNNEECCTTIINNGG DDEEVVIICCEE FFOOMM MMAAIINNSS

If an outdoor antenna is installed, follow the precau-
tions below. An outdoor antenna system should not
be located in the vicinity of overhead power lines or
other electric light or power circuits, or where it can
come in contact with such power lines or circuits as
death or serious injury can occur.
Be sure the antenna system is grounded so as to pro-
vide some protection against voltage surges and
built-up static charges.
Section 810 of the National Electrical Code (NEC) in
the U.S.A. provides information with respect to prop-
er grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna dis-
charge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding
electrodes and requirements for the grounding elec-
trode.
