20 ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the
precautions below. An outdoor antenna system
should not be located in the vicinity of
overhead power lines or other electric light or
power circuits, or where it can come in contact
with such power lines or circuits as death or
serious injury can occur.
Be sure the antenna system is grounded so as
to provide some protection against voltage
surges and built-up static charges.
Section 810 of the National Electrical Code
(NEC) in the U.S.A. provides information with
respect 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.

28 For LCD TV
If the TV feels cold to the touch, there may be
a small “flicker” when it is turned on. This is
normal, there is nothing wrong with TV.
Some minute dot defects may be visible on the
screen, appearing as tiny red, green, or blue
spots. However, they have no adverse effect on
the monitor's performance.
Avoid touching the LCD screen or holding your
finger(s) against it for long periods of time.
Doing so may produce some temporary
distortion effects on the screen.
