Outdoor antenna grounding
If an outdoor antenna is installed, follow the precautions below.

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.
Antenna grounding according to the National Electrical Code, 

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 

LCD TV is powered off.
