medical equipment.
Attachments
Do not use attachments not recommended by the manufacturer, as
they may cause hazards.
Wall-Mount
Wall-Mount installation requires the use of a Wall-Mount Bracket.
When installing or removing the TV, using a Wall-Mount Bracket,
be sure to use qualified contractors. If not properly secured during
installation or removal from the Wall-Mount Bracket, the TV may fall
and cause serious injury.
For use only with UL Listed Wall Mount Bracket with suitable weight/

injury.
AC Power Cable
Use the AC power cord specified by AOC and suitable for the
voltage where you use it.
The plug is designed, for safety purposes, to fit into the wall outlet
only one way. If you are unable to insert the plug fully into the
outlet, contact your dealer.
If you will not be using the TV for several days, disconnect the
power by pulling the plug itself. Never pull on the cord.
When disconnecting AC power cord, the power cord should be
easily accessible for disconnection.

English
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 of 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 and 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 ambient without an input source or a blank
screen. This condition is normal and not a malfunction of the TV.
Changing the Picture mode, Backlight setting, enabling the Light
Sensor, or turning on the Power management will improve this
condition.
Do not expose the LCD screen surface to direct sunlight. Doing so
may 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.
Ghosting may occur when still pictures are displayed continuously.
It should disappear after a few moments.
The screen and cabinet get warm when the TV is in use. This is
not a malfunction.
Avoid spraying insect repellent with volatile material on the
screen.
Avoid prolonged contact with rubber or plastic material.
Broken Pieces
Do not throw anything at the TV. The screen glass may break by the
impact and cause serious injury.
If the surface of the TV cracks, do not touch it until you have
unplugged the AC power cord. 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 let glass fragments or leaked
crystalline liquid get into your eyes or mouth. Should either contact
your eyes or mouth, rinse the contacted area thoroughly with water
and consult your doctor.
Wiring
When connecting cables, be sure to unplug the AC power cord for
your safety. Take care not to catch your feet on the cables. It may
damage the TV set.
Electric Shock
Do not touch the AC power cord or the TV with a wet hand. If you
plug/unplug the AC power cord from the TV with a wet hand, it may
cause electric shock.
Lightning Storms
For added protection for this TV during a lightning storm, or
when it is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the antenna. This will
prevent damage to the TV due to lightning and power line surges.
When Not in Use
If you will not be using the TV set for several days, the TV set should
be disconnected from the AC power outlet for environmental and
safety reasons. The TV set is not disconnected from the AC power
source when the TV set is switched off. To disconnect the TV set
completely, pull the plug from the AC power outlet.
Overloading
This TV set is designed to operate on a 120V AC supply only. Take
care not to connect too many appliances to the same AC power
outlet as this could result in a fire or an electric shock.

English
Optional Equipment
Do not install optional equipment too close to the TV set. Keep
optional equipment at least 11.875 inches (30 cm) away from the TV
set. If a VCR is installed in front of the TV set or beside the TV set,
the picture may become distorted. Picture distortion and/or noisy
sound may occur if the TV set is positioned in close proximity to any
equipment emitting electromagnetic radiation.
Small Accessories
Keep small accessories out of children’s reach.
Antennas
Outdoor antenna grounding
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.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM,
EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS CONTACT
WITH THEM IS ALMOST INVARIABLY FATAL.
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 USA and
Section 54 of the Canadian Electrical Code in Canada 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.
Antenna grounding according to the National Electrical Code,
ANSI/NFPA 70.

Cleaning
Cleaning the AC power plug
Unplug the AC power plug and clean it regularly. If the plug is
covered with dust and it picks up moisture, its insulation may
deteriorate and result in a fire.
Cleaning the screen surface/ cabinet of the TV set
Unplug the AC power cord to avoid electric shock when cleaning.
Clean the cabinet of the TV with a dry soft cloth. To remove dust
from the screen, wipe it gently with a soft cloth. Stubborn stains
may be removed with a cloth slightly dampened with a solution
of mild soap and warm water. Never use strong solvents such as
thinner or benzine for cleaning.
If using a chemically pretreated cloth, please follow the instruction
provided on the package.
The ventilation holes can accumulate dust over time. To ensure
proper ventilation, we recommend removing the dust periodically
(once a month) using a vacuum cleaner.
Magnetic Influence
This TV contains a strong magnet in the speaker unit that generates
a magnetic field. Keep any items susceptible to magnetic fields away
from the speaker.
