• Operate the system only on 9 V DC when using

batteries.
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.

• If the system is not to be used for a long period of

time or is to be operated extensively on AC power,
remove the batteries to avoid damage caused by
battery leakage and corrosion.

• 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, remove the batteries 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.

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.

The model number is located on the front of the unit
