• 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.

For your protection, please read these safety
instructions completely before operating the appliance,
and keep this manual for future reference.
Carefully observe all warnings, precautions and
instructions on the appliance, or the one described in
the operating instructions and adhere to them.
Use
Power sources
This set should be operated only
from the type of power source
indicated on the marking label. If
you are not sure of the type of

or other sources, refer to the operating instructions.
Grounding or Polarization
This set is equipped with a polarized ac power cord
plug (a plug having one blade wider than the other), or
with a three-wire grounding type plug (a plug having a
third pin for grounding). Follow the instructions
below:
For the set with a polarized AC power
cord plug:
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 should still fail to fit, contact your
electrician to have a suitable outlet installed. Do not
defeat the safety purpose of the polarized plug by
forcing it in.
For the set with a three-wire grounding
type AC plug:
This plug will only fit into a
grounding-type power outlet. This
is a safety feature. If you are
unable to insert the plug into the
outlet, contact your electrician to have a suitable outlet
installed. Do not defeat the safety purpose of the
grounding plug.
Overloading
Do not overload wall outlets,
extension cords or convenience
receptacles beyond their capacity,
since this can result in fire or
electric shock.
Object and Liquid Entry
Never push objects of any kind into
the set through openings as they
may touch dangerous voltage points
or short out parts that could result in
a fire or electric shock. Never spill
liquid of any kind on the set.
