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
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
grounding conductors, location of antenna dis- charge 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 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 LED TV is powered off.
