Warning - To reduce the risk of fire or
y y
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.

y y
do not place objects filled with liquids, such
as vases, cups, etc. on or over the apparatus
(e.g. on shelves above the unit).
Grounding
y y
(Except for devices which are not grounded.)
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
grounded AC outlet). If grounding methods
are not possible, have a qualified electrician
install a separate circuit breaker. Do not try to
ground the unit by connecting it to telephone
wires, lightening rods, or gas pipes.

ANTENNAS Outdoor antenna grounding
y y
(Can differ by country):
If an outdoor antenna is installed, follow
the precautions 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 provide
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
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.
