Antennas
Service
• 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.
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.
Antenna Grounding According to the
National Electrical Code
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.

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.
