ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the precautions below.
Do not install the outdoor antenna system near 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 that it can provide
some protection against voltage surges and built-up static
charges.
Section 810 of the National Electrical Code (NEC) in the U.S.A.
and Section 54 of the Canadian Electrical Code in Canada
provides information with in regard 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.

CLEANING
Cleaning the AC power plug
Unplug the AC power plug and clean it
regularly. If the plug is covered with dust and
gathers moisture, its insulation may deteriorate
and result in a fire.
Cleaning the screen surface/ cabinet of
the TV set
When cleaning this TV, unplug the AC power
cord. If not, it may result in electric shock. Use
a dry soft cloth to clean the cabinet of the TV. To remove dust
near 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 you to remove the
dust periodically (once a month) using a vacuum cleaner, while
the LED TV is powered off.
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.
SOUND
If you hear snapping or popping sound comes from
the TV continuously or frequently while the TV is
operating,
unplug the TV and consult your dealer or service
technician. It is normal for some TVs to make occasional
snapping or popping sounds, particularly when being turned on
or off.

follow these guidelines:
• Disconnect all cables before carrying the TV.
• Carrying the large size TV requires at least two or three
people.
• When you carry the TV, place your hands as illustrated and
hold it securely. Do not put stress on the LCD panel and the
frame around the screen.
• When carrying the TV, do not subject it to shocks, vibration,
or excessive force.
• When lifting or moving the TV, hold it securely from the
bottom. Place your palm directly under the panel.
VENTILATION
Slots and openings in TV are provided for
ventilation. To ensure reliable operation of the
TV and to protect it from overheating, be sure
these openings are not blocked or covered.
The TV may accumulate dust and get dirty if
proper ventilation is not provided. For proper
ventilation, follow the following guidelines:
• Never install the TV face up, down or
sideways.
• Never install the TV turned over or upside
