moving the cart/apparatus combination to avoid
injury from tip-over.
Unplug this apparatus during lightning storms or
y
when unused for long periods of time.
CAUTION concerning the Power Cord
y
(Can differ by country):
It is recommended 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 electric
shock. Do not overload wall outlets. Overloaded
wall outlets, 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 service. 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 move 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.

Grounding
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.

Dot Defect
y
The Plasma or LCD panel is a high technology
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’re viewing the TV. Those
dots are deactivated pixels and do not affect the
performance and reliability of the TV.
Generated Sound
y
“Cracking” noise: A cracking noise that occurs
when watching or turning off the TV is generated by
plastic thermal contraction due to temperature and
humidity. This noise is common 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
performance and reliability of the product.
Take care not to touch the ventilation openings.
y
When watching the TV for a long period, the
ventilation openings may become hot. This does
not affect the performance of the product or cause
defects in the product.
If the TV feels cold to the touch, there may be a
y
small “flicker” when it is turned on. This is normal,
there is nothing wrong with TV. Some minute dot
defects may be visible on the screen, appearing as
tiny red, green, or blue spots. However, they have
no adverse effect on the TV’s performance. Avoid
touching the LCD screen or holding your finger(s)
against it for long periods of time. Doing so may
produce some temporary distortion effects on the
screen.
