ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the precautions
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
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 re.
Cleaning the screen surface/ cabinet of the display set
When cleaning this display, unplug the AC
power cord. If not, it may result in electric
shock. Use a dry soft cloth to clean the
cabinet of the display. 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 display is powered off.
