SAFETY INSTRUCTIONS
WARNING - To reduce the risk
14
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 prod-
uct near flammable objects
such as gasoline or candles or
expose the TV to direct air
conditioning.
15 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).
GROUNDING
16
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 con-
nected 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.
Short-circuit
17
DISCONNECTING DEVICE FROM MAINS
Mains plug is the disconnecting device. The
plug must remain readily operable.
18
As long as this unit is connected to the AC
wall outlet, it is not disconnected from the AC
power source even if you turn off this unit by
SWITCH.
Cleaning
19
When cleaning, unplug the power cord and
scrub gently with a soft cloth to prevent
scratching. Do not spray water or other liquids
directly on the TV as electric shock may
occur. Do not clean with chemicals such as
alcohol, thinners or benzene.

Moving
20
Make sure the product is turned off,
unplugged and all cables have been
removed. It may take 2 or more people to
carry larger TVs. Do not press against or put
stress on the front panel of the TV.
21 Ventilation
Install your TV where there is proper ventila-
tion. Do not install in a confined space such
as a bookcase. Do not cover the product
with cloth or other materials (e.g.) plastic
while plugged in. Do not install in exces-
sively dusty places.
Take care not to touch the ventilation open-
22
ings. When watching the TV for a long
period, the ventilation openings may
become hot.
23 If you smell smoke or other odors coming
from the TV, unplug the power cord and con-
tact and authorized service center.
Do not press strongly upon the
24
panel with hand or sharp object
such as nail, pencil or pen, or
make a scratch on it.
25
Keep the product away from direct sunlight.
Dot Defect
26
The Plasma or LCD panel is a high technol-
ogy product with resolution of two million to
six million pixels. In a very few cases, you
could see fine dots on the screen while
you'reviewing the TV. Those dots are deacti-
vated pixels and do not affect the perfor-
mance and reliability of the TV.
Generated Sound
27
"Cracking" noise: A cracking noise that occurs
when watching or turning off the TV is gener-
ated by plastic thermal contraction due to
temperature and humidity. This noise is com-
mon for products where thermal deformation
is required.
Electrical circuit humming/panel buzzing: A
low level noise is generated from a high-speed
switching circuit, which supplies a large amount
of current to operate a product. It varies
depending on the product.
This generated sound does not affect the per-
formance and reliability of the product.
