Connecting Additional Equipment 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.

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.

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

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

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
