Ventilation
The slots and openings in the cabinet and in the back or
bottom are provided for necessary ventilation. To ensure
reliable operation of the set, and to protect it from
overheating, these slots and openings must never be
blocked or covered.
•
Never cover the slots and openings
with a cloth or other materials.
• Never block the slots and
openings by placing the set on a
bed, sofa, rug or other similar
surface.
• Never place the set in a confined
space, such as a bookcase or built-in
cabinet, unless proper ventilation is
provided.
• Do not place the set near or over a
radiator or heat register, or where it is
exposed to direct sunlight.
Power-Cord Protection
Do not allow anything to rest on or roll over
the power cord, and do not place the set where
the power cord is subject to wear or abuse.
Grounding or Polarization
This set may be equipped with a polarized
alternating current line plug (a plug
having one blade wider than other). This plug will fit into
the power outlet only one way. This is a safety feature. If
you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug still fails to fit, contact your
electrician to replace your obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
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.
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 as to provide
some protection against voltage surges and built-up static
charges. Section 810 of the National Electrical Code (NEC)
in USA and Section 54 of the Canadian Electrical Code in
Canada 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.

Lightning
For added protection for this television receiver during a
lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and
disconnect the antenna. This will prevent damage to the
receiver due to lightning and power-line surges.
Service
Damage Requiring Service
Unplug the set from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
• When the power cord or
plug is damaged or frayed.
• If liquid has been spilled
into the set or objects have
fallen into the product.
• If the set has been exposed to
rain or water.
•
If the set has been subject to
excessive shock by being
dropped, or the cabinet has
been damaged.
• If the set does not operate
normally when following the operating
instructions. Adjust only those controls
that are specified in the operating
instructions. Improper adjustment of
other controls may result in damage
and will often require extensive work
by a qualified technician to restore the
set to normal operation.
• When the set exhibits a distinct change in
performance — this indicates a need for service.
