Sony WEGA KV-36XBR250, KV-32XBR250 Operating Instructions Manual page 6

Important Safeguards (continued)
• 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
Antenna lead-in wire
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
Antenna discharge unit
qualified technician to restore the set to
(NEC Section 810-20)
normal operation.
• When the set exhibits a distinct change in performance —
Grounding conductors
(NEC Section 810-21)
this indicates a need for service.
Ground clamps Servicing
Do not attempt to service the set yourself
since opening the cabinet 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 certifies in writing that he 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, and to so certify.
When the set reaches the end of its useful
life, improper disposal could result in a
picture tube implosion. Ask a qualified
service technician to dispose of the set.
