To prevent the TV from toppling over, secure the
TV to a wall or stand.

Placement for watching

We suggest you to watch the TV at a distance
of 3-7 times that of the screen height, and not
in excessive brightness. It is easy to cause eye
fatigue if you watch TV for too long or in a dark
room. To obtain clear picture, do not expose the
screen to direct illumination or sunlight. Use spot
lighting directed down from the ceiling if you can.

Use in outdoor

This TV is not designed for
outdoors installation. Do not
expose the TV to rain, as it may
result in a fire or an electric shock.
Also, do not expose the TV to
direct sunlight, as it may heat up
and become damaged.

VOLUME ADJUSTMENT

¸ Adjust the volume to avoid disturbing your

neighbors. Sound carries easily at night.
Therefore, we suggest you close the windows
or use headphones.

¸ When using headphones, adjust the volume

to appropriate levels, or hearing damage may
result.

LCD SCREEN

¸ Although the LCD screen is made with high-

precision technology and has effective
pixels of 99.99% or more, black dots or
bright points or light (red, blue, or green)
may appear constantly on the LCD screen.
This is a structural property of the LCD
panel and is not a malfunction.

¸ The LCD screen is made with high-precision

technology. To achieve a high level of
performance and picture quality, this TV’s
backlight setting is set to maximize the
brightness of the TV. However, uneven
brightness may be observed when the LCD TV
is viewed in a dark environment without an
input source or a blank screen. This is a normal
condition, not a malfunction of the TV. To
improve this condition, change the Picture
mode, Backlight setting, enable the Light
Sensor, or turn on the Power management.

¸ Avoid exposing the LCD screen surface to

direct sunlight. It is likely to damage the LCD
panel.

¸ Do not push or scratch the LCD screen, or place

objects on top of the TV. The image may be
uneven or the LCD panel may be damaged.

¸ If the TV is used in a cold place, a smear may

occur in the picture or the picture may become
dark. This does not indicate a failure. These
phenomena improve as the temperature rises.

¸ When still pictures are displayed continuously,

ghosting may occur. It should disappear after a
short period of time.

¸ The screen and cabinet get warm when the TV

is in use. This is a normal condition.

¸ Spraying insect repellent with volatile material

on the screen will cause damage.

¸ Do not make prolonged contact with rubber

or plastic material.

Broken pieces

Do not throw anything at the TV.
Doing so may break the screen glass
and cause serious injury.
If the surface of the TV cracks, unplug
the AC power cord before touching the
TV. Otherwise electric shock may result.

Handling of broken glass and liquid
crystal leakage

If the LCD panel gets damaged, crystalline liquid
leakage may occur, or scattered broken glass may
result. Do not touch broken glass or crystalline
liquid which is toxic, with bare hands as cuts,
poisoning or skin irritation may occur. Also do not
glass fragments or leaked crystalline liquid get
into your eyes or mouth. Should either contacted
your eyes or mouth, rinse the contacted area
thoroughly with water and consult your doctor.

SERVICING

Do not attempt to repair the TV
yourself, since opening the cabinet
may expose you to dangerous
voltage or other hazards. Ask qualified service
personnel to do the servicing for your TV.

Replacement parts

When replacement parts are required, be sure
the service technician certifies in writing that
he/she has used replacement parts specified by
the manufacturer that have the same
characteristics as the original parts.
Unauthorized substitutions may cause a fire,
an electric shock or other hazards.

Safety check

Upon completion of repairs to the TV, ask the
service technician to perform routine safety
checks (as specified by the manufacturer) to
determine that the TV is safe for operating, and
to so certify. Ask a qualified service technician
to dispose of the TV.
