Lightning storms
During a lightning storm, unplug the TV from the
wall outlet and disconnect the antenna to prevent
damage to the TV.
When not in use
If you will not be using the TV set for long peri-
ods of time, the TV set should be disconnected
from the AC power outlet to prevent power line
surges. The TV set is not disconnected from the
AC power source when the TV set is switched off.
To disconnect the TV set completely, unplug from
the AC power outlet.
Overloading
This TV set is designed to operate on
a 120 - 240 V AC supply only. If
there are too many appliances con-
nected to the same AC power outlet,
it could result in a fire or an electric
shock.
Optional equipment
If optional equipment is to be installed, leave
some space between optional equipment and the
TV set. Picture distortion and/or noisy sound may
occur if the TV set is positioned in close proxim-
ity to any equipment emitting electromagnetic
radiation.
Small accessories
Keep small accessories in a safe place where chil-
dren are unable to reach.
ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the pre-
cautions 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 CON-
TACTING SUCH POWER LINES OR CIR-
CUITS 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 Cana-
dian Electrical Code in Canada provides informa-
tion 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 dis-
charge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
Antenna grounding according to the
National Electrical Code, ANS/NFPA 70
BATTERIES
• Do not cast away batteries in a fire.
• Do not disassembled, overheat, or short-circuit the
batteries.
• If the battery is replaced in the wrong way, it may cause
danger of explosion. Replace only with the same or equiv-
alent type.

CLEANING
Cleaning the AC power plug
Unplug the AC power plug and
clean it regularly. If the plug is cov-
ered 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 pre-
treated cloth, please follow the instruction pro-
vided 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 LCD TV is
powered off.
