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.

ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the precau-
tions 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 pro-
vide 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 prop-
er grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna dis-
charge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding
electrodes and requirements for the grounding elec-
trode.
Antenna grounding according to the
National Electrical Code, ANSI/NFPA 70
Cleaning
When cleaning, unplug the power cord and scrub
gently with a soft cloth to prevent scratching. Do not
spray water or other liquids directly on the TV as
electric shock may occur. Do not clean with chemi-
cals such as alcohol, thinners or benzene.
Moving
Make sure the product is turned off, unplugged
and all cables have been removed. It may take 2 or
more people to carry larger TVs. Do not press
against or put stress on the front panel of the TV.
Ventilation
Install your TV where there is proper ventilation. Do
not install in a confined space such as a bookcase.
Do not cover the product with cloth or other mate-
rials (e.g.) plastic while plugged in. Do not install in
excessively dusty places.
If you smell smoke or other odors coming from the
TV or hear strange sounds, unplug the power cord
contact an authorized service center.
Do not press strongly upon the panel with a hand or
sharp object such as nail, pencil or pen, or make a
scratch on it.
