Notes on discs
•Before playing, clean the disc with a cleaning cloth.
Wipe the disc from the center out.
•Do not use solvents such as benzene, thinner,
commercially available cleaners or anti-static spray
intended for vinyl LPs.
•Do not expose the disc to direct sunlight or heat
sources such as hot air ducts, nor leave it in a car
parked in direct sunlight.
•Do not use discs encircled with a protection ring.
This may cause a malfunction to the system.
•When using discs that have glue or similar tacky
substance on the label side of the disc or that used a
special ink when the label was printed, there is a
chance that the disc or label may become attached
to parts inside this unit. When this occurs, it may
not be possible to remove the disc, and may also
cause this unit to malfunction. Be sure to check that
the label side of the disc is not sticky before using.
The following types of disc should not be used:
—Rental or used discs with attached seals where
the glue extends beyond the seal. The perimeter
of the seal on the disc is tacky.
—Discs that have labels printed using a special ink
that feels tacky when touched.
•Discs with non-standard shapes (e.g., heart, square,
star) cannot be played on this unit. Attempting to do
so may damage the unit. Do not use such discs.
Note on CD-R/CD-RW playback
Discs recorded on CD-R/CD-RW drives may not be
played back because of scratches, dirt, recording
condition or the drives characteristics. Besides, the
discs, which are not yet finalized at the end of
recording, cannot be played back.
Cleaning the cabinet
Use a soft cloth slightly moistened with mild
detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded
over, break off the cassette tab from side A or B as
illustrated.
If you later want to reuse the tape for recording, cover
the broken tab with adhesive tape.

Precautions
On operating voltage
Before operating the unit, check that the operating
voltage of your unit is identical with the voltage of
your local power supply.
On safety
•The unit is not disconnected from the AC power
source (mains) as long as it is connected to the wall
outlet, even if the unit itself has been turned off.
•Unplug the unit from the wall outlet (mains) if it is
not to be used for an extended period of time. To
disconnect the cord (mains lead), pull it out by the
plug. Never pull the cord itself.
•Should any solid object or liquid fall into the
component, unplug the unit and have the
component checked by qualified personnel before
operating it any further.
•The AC power cord must be changed only at a
qualified service shop.
On placement
•Do not place the unit in an inclined position.
•Do not place the unit in locations where it is:
— extremely hot or cold
— dusty or dirty
— very humid
— vibrating
— subject to direct sunlight.
•Use caution when placing the unit or speakers on
surfaces that have been specially treated (with wax,
oil, polish, etc.) as staining or discoloration of the
surface may result.
On heat buildup
•Although the unit heats up during operation, this is
not a malfunction.
•Place the unit in a location with adequate
ventilation to prevent heat build-up in the unit.
If you continuously use this unit at a large volume,
the cabinet temperature of the top, side and bottom
rises considerably. To avoid burning yourself, do not
touch the cabinet.
To prevent a malfunction, do not cover the ventilation
hole for the cooling fan.
On operation
•If the unit is brought directly from a cold to a warm
location, or is placed in a very damp room, moisture
may condense on the lens inside the CD player.
Should this occur, the unit will not operate properly.
Remove the CD and leave the unit turned on for
about an hour until the moisture evaporates.
•When you move the unit, take out any discs.
If you have any questions or problems concerning the
unit, please consult your nearest Sony dealer.

Before placing a cassette in the tape
deck
Take up any slack in the tape. Otherwise the tape may
get entangled in the parts of the tape deck and become
damaged.
When using a tape longer than
90 minutes
The tape is very elastic. Do not change the tape
operations such as play, stop, and fast-winding etc.
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
Make sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
a separately sold dry-type or wet-type cleaning
cassette. For details, refer to the instructions of the
cleaning cassette.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that
have contact with the tape every 20 to 30 hours of use
with a separately sold demagnetizing cassette. For
details, refer to the instructions of the demagnetizing
cassette.
In case color irregularity is observed
on nearby a TV screen
With the magnetically shielded type of speaker
system, the speakers can be installed near a TV set.
However, color irregularity may still be observed on
the TV screen depending on the type of your TV set.
If color irregularity is observed…
Turn off the TV set, then turn it on after 15 to 30
minutes.
If color irregularity is observed
again…
Place the speakers farther away from the TV set.

Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two-channel sound. Compared
with the former Dolby Surround system, Dolby
Pro Logic Surround reproduces left-to-right
panning more naturally and localizes sounds
more precisely. To take full advantage of
Dolby Pro Logic Surround, you should have
one pair of rear speakers and a centre speaker.
The rear speakers output monaural sound.
DTS
Digital audio compression technology that the
Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround.
The rear channel is stereo and there is discrete
subwoofer channel in this format. DTS
provides the same 5.1 discrete channels of high
quality digital audio. The good channel
separation is realized because the all channel
data is recorded discrete and processed in
digital.
DVD
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same as
a CD.
The data capacity of a single-layer and single-
sided DVD, at 4.7 GB (Giga Byte), is 7 times
that of a CD. Furthermore, the data capacity of
a dual-layer and single-sided DVD is 8.5 GB, a
single-layer and double-sided DVD 9.4 GB,
and a dual-layer and double-sided DVD 17 GB.
The picture data uses the MPEG 2 format, one
of the worldwide standards of digital
compression technology. The picture data is
compressed to about 1/40 of its original size.
The DVD also uses the variable rate coding
technology that changes the data to be allocated
according to the status of the picture.
The audio data is recorded in Dolby Digital as
well as in PCM, allowing you to enjoy more
real audio presence. Furthermore, various
advanced functions such as the multi-angle,
multilingual, and Parental Control functions are
provided with the DVD.
Glossary
Album
Section of a music piece on a data CD
containing MP3 audio tracks.
Bit Rate
Value indicating the amount of video data
compressed in a DVD per second. The unit is
Mbps (Mega bit per second). 1 Mbps indicates
that the data per second is 1,000,000 bits. The
higher the bit rate is, the larger the amount of
data. However, this does not always mean that
you can get higher quality pictures.
Chapter
Sections of a picture or a music piece on a
DVD that are smaller than titles. A title is
composed of several chapters.
Dolby Digital
This sound format for movie theaters is more
advanced than Dolby Pro Logic Surround. In
this format, the rear speakers output stereo
sound with an expanded frequency range and a
subwoofer channel for deep bass is
independently provided. This format is also
called “5.1” because the subwoofer channel is
counted as 0.1 channel (since it functions only
when a deep bass effect is needed). All six
channels in this format are recorded separately
to realize superior channel separation.
Furthermore, since all the signals are processed
digitally, less signal degradation occurs.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from two-channel sources.
This is done using an advanced, high-purity
matrix surround decoder that extracts the
spatial properties of the original recording
without adding any new sounds or tonal
colorations.
