Precautions
• Operate the system only on 15 V DC.
For AC operation, use only the supplied AC power
adaptor. Do not use any other AC power adaptor.
• 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 system does not turn the AC power adaptor off.
• Do not open the cabinet. 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 the
system, disconnect the AC power adaptor and have
the system checked by qualified personnel before
operating it any further.
• Do not use alcohol, benzine or thinner to clean the
cabinet.
• Although this system is magnetically shielded, 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.
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.
