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.
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 provide
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 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, it
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.
