IMPORTANT SAFEGUARDS

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 and in the operating
instructions, and adhere to them.

INSTALLATION

Water and Moisture

Do not use powerline operated appliances near water - for example, near a bathtub, washbowl,
kitchen sink, or laundry tub, in a wet basement, or near a swimming pool, etc.

Heat

Do not place the appliance near or over a radiator or heat register, or where it is exposed to direct
sunlight.

Ventilation

The slots and openings in the cabinet are provided for necessary ventilation. To ensure reliable
operation of the appliance, and to protect it from overheating, these slots and openings must never be
blocked or covered.

-Never cover the slots and openings with a cloth or other materials.

-Never block the slots and openings by placing the appliance on a bed, sofa, rug or other similar
surface.

-Never place the appliance in a confined space, such as a bookcase, or built-in cabinet, unless proper
ventilation is provided.

Accessories

Do not place the appliance on an unstable cart, stand, tripod, bracket, or table. The appliance may fall,
causing serious injury to a child or an adult, and serious damage to the appliance. Use only a cart,
stand, tripod, bracket, or table recommended by Sony.

-An appliance and cart combination should be moved with care. Quick stops, excessive force, and
uneven surfaces may cause the appliance and cart combination to overturn.

Wall or Ceiling Mounting

If your appliance can be mounted to a wall or ceiling, mount it only as recommended by Sony.

USE

Power Source

This appliance should be operated only from the type of power source indicated on the marking label.
If you are not sure of the type of electrical power supplied to your home, consult your dealer or local
power company. For those appliances designed to operate from battery power, or other sources, refer
to the operating instructions.

Grounding or Polarization

This appliance 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 appliance 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 appliance 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.

When not in use

Unplug the power cord of the appliance from the outlet when left unused for a long period of time.
To disconnect the cord, pull it out by grasping the plug. Never pull the plug out by the cord.

Power-Cord Protection

Route the power cord so that it is not likely to be walked on or pinched by items placed upon or
against them, paying particular attention to the plugs, receptacles, and the point where the cord exits
from the appliance.

Lightning

For added protection for this appliance 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 appliance due to lightning and powerline surges.

Object and Liquid Entry

Never push objects of any kind into the appliance 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 appliance.

Cleaning

Unplug the appliance from the wall outlet before cleaning or polishing it. Do not use liquid cleaners
or aerosol cleaners. Use a cloth lightly dampened with water for cleaning the exterior of the appliance.
Clean the appliance only as recommended by Sony.

Attachments

Do not use attachments not recommended by Sony, as they may cause hazards.

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.

Antenna Grounding According to the National
Electrical Code

SERVICE

Damage Requiring Service

Unplug the appliance from the wall outlet and refer servicing to qualified service personnel under the
following conditions:

-When the power cord or plug is damage or frayed.

-If liquid has been spilled or objects have fallen into the appliance.

-If the appliance has been exposed to rain or water.

-The appliance does not appear to operate normally or exhibits a marked change in performance.

-This indicates a need for service.

-If the appliance does not operate normally when following the operating instructions, adjust only

may result in damage and will often require extensive work
by a qualified technician to restore the appliance to normal operation.

-If the appliance has been subject to excessive shock by being dropped, or the cabinet has been
damaged.

Servicing

Do not attempt to service the appliance 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 Sony 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 appliance, ask the service technician to perform
routine safety checks (as specified by Sony) to determine that the appliance is in safe operating
condition.
