❑ 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.
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
Refer to section 54-300 of Canadian Electrical Code for
Antenna Grounding.
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.
❑ 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, it indicates a need for service.
