Protect the power cord from being walked on

y

or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.

Only use attachments/accessories specified

y

by the manufacturer.

Use only with a cart, stand, tripod, bracket,

y

or table specified by the manufacturer, or
sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus
combination to avoid injury from tip-over.

Unplug this apparatus during lightning

y

storms or when unused for long periods of
time.

Refer all servicing to qualified service

y

personnel. Servicing is required when
the apparatus has been damaged in any
way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does
not operate normally, or has been dropped.

Keep the packing anti-moisture material or

y

vinyl packing out of the reach of children.
Anti-moisture material is harmful if
swallowed. If swallowed by mistake, force
the patient to vomit and visit the nearest
hospital. Additionally, vinyl packing can
cause suffocation. Keep it out of the reach of
children.
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.

ENGLISH

ENG

Do not stick metal objects or any other

y

conductive material into the power cord. Do
not touch the end of the power cord while it
is plugged in.

Warning

y

- 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

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

(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

(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.

If you smell smoke or other odors coming

y

from the TV, unplug the power cord and
contact an authorized service center.
Do not press strongly upon the panel with a

y

hand or a sharp object such as a nail, pencil
or pen, or make a scratch on it.
Keep the product away from direct sunlight.

y

Never touch this apparatus or antenna during

y

a thunder or lightning storm.
When mounting a TV on the wall, make sure

y

not to install the TV by hanging the power
and signal cables on the back of the TV.
Do not allow an impact shock or any objects

y

to fall into the product, and do not drop
anything onto the screen.

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 high­speed 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

y

openings. 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

y

be a 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.

DISPOSAL (Hg lamp only used in LCD TVs)

The fluorescent lamp used in this product contains
a small amount of mercury. Do not dispose of this
product with general household waste. Disposal of
this product must be carried out in accordance to
the regulations of your local authority.

Preventing “Image burn” or “Burn-in” on your TV screen

If a fixed image displays on the TV screen

y

for a long period of time, it will be imprinted
and become a permanent disfigurement on
the screen. This is “image burn” or “burn-in”
and not covered by the warranty.
If the aspect ratio of the TV is set to 4:3 for

y

a long period of time, image burn may occur
on the letterboxed area of the screen.
Avoid displaying a fixed image on the TV

y

screen for a long period of time (2 or more
hours for LCD, 1 or more hours for the
Plasma TV) to prevent image burn.

For USA and Canada

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.
