• 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.
Antennas
Outdoor antenna grounding
If an outdoor antenna or cable system 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 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 set 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 or cable system. This
will prevent damage to the set 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 or
objects have fallen into the set.
• 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 as opening or removing
covers 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 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.
