Connecting Additional Equipment
•
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.
Antenna Grounding According to the NEC
Antenna Grounding According to the National Electrical Code,
ANSI/NFPA 70.
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.
Servicing
Do not attempt to service the set yourself since
opening the cabinet may expose you to
dangerous voltage or other hazards. Refer all
servicing to qualified service personnel.
Replacement Parts
When replacement parts are required, be
sure the service technician certifies in
writing that he has used replacement parts
specified by the manufacturer that have the
same characteristics as the original parts.
Unauthorized substitutions may result in
fire, electric shock, or other hazards.
Safety Check
Upon completion of any service or repairs to the
set, ask the service technician to perform routine
safety checks (as specified by the manufacturer)
to determine that the set is in safe operating
condition, and to so certify. When the set reaches
the end of its useful life, improper disposal could
result in a picture tube implosion. Ask a qualified
service technician to dispose of the set.
