Precautions

On safety
The nameplate is located on the rear exterior of the system.

• Before operating the system, be sure that the operating voltage of the system is identical to that of your local power supply.

  Where purchased	Operating voltage
  All countries/regions 100 – 240 V AC,	50/60 Hz

• Use only the supplied AC power adaptor

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.

On placement

• Do not set the speakers in an inclined position.
• 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.

On cleaning
Do not use alcohol, benzine or thinner to clean the cabinet.

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 computers may become magnetically distorted. In such a case, turn off the power of the TV set/personal computer once, and after 15 to 30 minutes turn it on again. In the case of a personal computer, take appropriate measures such as data storage before turning off.
If no improvement is apparent, locate the system farther away from the TV set/personal computer. Furthermore, be sure not to place objects in which magnets are attached or used, such as audio racks, TV stands, toys, etc, near the TV set/personal computer. These may cause magnetic distortion to the picture due to magnetic interaction.
If you have any questions or problems concerning this system that are not covered in this manual, please consult your nearest Sony dealer.
