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:
