Precautions
On safety
 AC cord must be changed only at the qualified service shop.
 Use only the supplied AC power adaptor. Do not use any other AC power adaptor.
Polarity of the plug
 The nameplate is located on the bottom exterior.
 Before operating the system, be sure that the operating voltage of the system is
identical with that of your local power supply.
Where purchased Operating voltage
All countries/regions 100 V - 240 V AC, 50/60 Hz
 The main unit is not disconnected from the AC power source (mains) as long as it is
connected to the AC outlet, even if the main unit itself has been turned off.
 After operating the system with the AC power adaptor, disconnect the AC power
adaptor from the wall outlet if the system is not to be used for an extended period of
time. Just switching the / (power/standby) button to standby does not turn the AC
power adaptor off.
On placement
 Do not place the system in an inclined position.
 Do not place the system in locations that are hot and subject to direct sunlight, dusty,
very humid, or extremely cold.
 Do not leave the system in a location near heat sources, or in a place subject to direct
sunlight, excessive dust, moisture, rain or mechanical shock.
 Use caution when placing the system or AC power adaptor on a specially treated
(waxed, oiled, polished, etc.) floor, as staining or discoloration may result.
On cleaning
 Clean the cabinet, panel, and controls with a soft cloth slightly moistened with a mild
detergent solution. Do not use any type of abrasive pad, scouring powder or solvent
such as alcohol or benzine.
If you have any questions or problems concerning your system, please consult your
nearest Sony dealer.
On operation
 Should any solid object or liquid fall into the system, have the system checked by
qualified personnel before operating it any further.
 Although this system is magnetically shielded, do not leave recorded tapes, watches,
personal credit cards, or floppy disks with magnetic coding in front of the system for
an extended period of time.
If the TV picture or monitor display is magnetically distorted
 Although this system is magnetically shielded, there may be cases that the picture on
some TV sets/personal computer sets may become magnetically distorted. In such a
case, turn off the power of the TV set/personal computer set once, and after 15 to 30
minutes turn it on again. For the personal computer set, take the appropriate measures
such as data storage before turning it off.
When there seems to be no improvement, locate the system further away from the TV
set/personal computer set. Furthermore, be sure not to place objects in which magnets
are attached or used near the TV set/personal computer set, such as audio racks, TV
stands, toys etc. These may cause magnetic distortion to the picture due to their
interaction with the system.
