ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the
precautions below. Do not install the outdoor antenna
system in 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 fi re.
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 form
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 LCD TV is powered off.
