Placing on top of the desk
Notes
• The supplied mounting brackets may not fit some
PC monitors. In such a case, place the system
beside the computer on top of the desk.
• Clean the surface of the mounting brackets and
the PC monitor before attaching the double-sided
tapes. Otherwise, the double-sided tapes may not
adhere firmly to the surface of the PC monitor and
the system may fall off.
• To attach the system to the PC monitor firmly
using the double-sided tapes, press the mounting
bracket firmly to the PC monitor.
Installation
Installing to the PC monitors
•If the picture on the PC monitor is distorted by the
vibration from the speaker system, turn down the
volume first. If there seems to be no
improvement, try placing the speaker system on
top of a desk etc.
•Depending on the mounting surfaces, there may
be cases in which the mounting brackets becomes
difficult to remove once attached. Also the
double-sided tapes used on the mounting
brackets may leave some marks on the surface of
the PC monitor when they are removed.
• Use only the supplied AC power adaptor for
operating the system. Do not use any other AC
power adaptors.
• 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. The POWER switch
on the left speaker does not turn the AC power
adaptor off.
• Do not open the speaker cabinets. Refer servicing
to qualified personnel only.
• 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.
• Should any solid object or liquid fall into either
speaker, disconnect the AC power adaptor and
have the speaker checked by qualified personnel
before operating it any further.
• When the speaker cabinet becomes soiled, clean it
with a soft cloth slightly moistened with a mild
detergent solution. Never use alcohol, benzine or
thinner as they may mar the finish.
• Although this system is magnetically shielded, as
a precaution, do not leave recorded tapes,
watches, personal credit cards or floppy disks
using magnetic coding in front of the system for
an extended period of time.

Specifications
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.
If you have any questions or problems concerning
your system that are not covered in this manual,
please consult your nearest Sony dealer.
