Model No.SRS-T70
Serial No.___________________

When the AC power adaptor is connected to the
system, internal batteries are automatically
disconnected.

When the batteries are weak, the POWER indicator
will start flickering and become faint, or the playback
sound will become distorted or unstable.
In such a case, replace all the batteries with new ones.
For battery life, see “Specifications.”

• Operate the system only on 6 V DC (four size AA

(R6) batteries) or 9 V DC (optional AC Power
adaptor).
For AC operation, use only the AC-E90HG AC
power adaptor (not supplied).  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 a mechanical shock.

• Should any liquid or solid object 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.
