other appliances that produce heat.
Slots and openings in the cabinet and in the back or bottom are provided for necessary ventilation.
To ensure reliable and safe operation of the appliance, and to protect it from overheating, these
slots and openings must never be blocked or covered.
Do not place the appliance on a bed, sofa, rug or other similar surface which may block the slots
and openings.
Do not install the appliance in a confined space, such as a bookcase or built-in cabinet, unless
proper ventilation is provided.
Carts and Stands
Do not install the appliance on an unstable table, shelf, cart or stand. Use only a cart or stand
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.
Power Source
Connect the appliance to a power supply only of the type described in the operating instructions
or as marked on the appliance.
Grounding or Polarization
Do not defeat the grounding or polarization feature of the AC power cord. If your AC receptacle
will not accept the power cord plug, contact your electrician to install a proper AC receptacle.
AC Receptacle
Check to make sure that the AC receptacle holds the power cord plug firmly and securely. If the
power cord plug is loose, contact your electrician to replace the defective and unsafe AC
Power-Cord Protection
Route the power cord so that it is not likely to be walked on or pinched by having objects placed
on it, paying particular attention to the plugs, receptacles, and the point where the cord exits from
the appliance.

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.
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
Unplug the appliance from the wall outlet and consult qualified service personnel when:
-the power cord or the plug has been damaged.
-a solid object or liquid has fallen into the cabinet.
-the appliance has been exposed to rain or moisture.
-the appliance does not appear to operate normally or exhibits a marked change in performance.
-the appliance has been dropped, or the enclosure damaged.
