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. NEC: National Electrical Code 
BATTERIES
¸ Do not cast away batteries in a fire.
¸ Do not disassembled, overheat, or short-circuit 
the batteries. 
¸ If battery replaced in the wrong way, it may 
cause danger of explosion. Replace only with

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.
