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 it off.
When there seems to be no improvement, 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 near the TV set/
personal computer, such as audio racks, TV stands, toys
etc. These may cause magnetic distortion to the picture
due to their interaction with the system.

• 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.

Do not use alcohol, benzene, or thinner to clean the
cabinet.

If you have any questions or problems concerning your
speaker system, please consult your nearest Sony
dealer.
