Connecting Additional Equipment

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, 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
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.
