Notes on CD-R and CD-RW
• This system can play CD-R/CD-RW discs
edited by the user. However, note that
playback of some discs may not be possible
depending on the recording device used for
recording or the disc condition.
• Discs recorded on CD-R/CD-RW drives may
not be played back because of scratches, dirt,
recording condition or the driver’s
characteristics.
• CD-R and CD-RW discs that have not been
finalized (processing to allow play by a
normal CD player) cannot be played.
• CD-R and CD-RW discs recorded in multi-
session that have not ended by “closing the
session” are not supported.
• The system may be unable to play MP3
format files that do not have the extender
“.MP3”.
• Attempting to play non-MP3 format files that
have the extender “.MP3” may result in noise
or malfunction.
• With formats other than ISO 9660 level 1 and
2, folder names or file names may not be
displayed correctly.
• The following discs take a longer time to start
playback.
– a disc recorded with complicated tree
structure.
– a disc recorded in Multi Session.
– a disc to which data can be added (non-
finalized disc).
Music discs encoded with
copyright protection
technologies
This product is designed to playback discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with
copyright protection technologies are marketed
by some record companies. Please be aware that
among those discs, there are some that do not
conform to the CD standard and may not be
playable by this product.
Cautions when playing a disc
that is recorded in Multi
Session
• If the disc begins with a CD-DA session, it is
recognized as a CD-DA (audio) disc, and
playback continues until an MP3 session is
encountered.
• If the disc begins with an MP3 session, it is
recognized as an MP3 disc, and playback
continues until a CD-DA (audio) session is
encountered.
• The playback range of an MP3 disc is
determined by the tree structure of files
produced by analyzing of the disc.
• A disc with a mixed CD format will be
recognized as a CD-DA (audio) disc.

Inserting two R6 (size AA)
batteries into the remote
Note
If you do not use the remote for a long period of time,
remove the batteries to avoid possible damage from
battery leakage and corrosion.
Tip
With normal use, the batteries should last for about six
months. When the remote no longer operates the
system, replace both batteries with new ones.
Attaching the speaker pads
Attach the supplied front speaker pads to the
bottom of the speakers to stabilize the speakers
and prevent them from slipping.

Placing the Sub woofer
(MHC-GX45 and MHC-RG440S
only)
Since the human ear cannot detect the direction
and position where the bass sound being
reproduced by a subwoofer (below 150 Hz)
comes from, you can place the subwoofer
wherever you like in your room. To obtain a
better bass reproduction, we recommend you to
place the subwoofer on a solid floor where
resonance is unlikely to occur.
Notes
• Always place the subwoofer vertically, keeping it a
few centimeters away from the wall.
• If the subwoofer is placed in the center of a room, the
bass could be extremely weakened. This is due to the
influence of the standing wave of the room. If this
happens, move the subwoofer away from the center
of the room or eliminate the cause of the standing
wave, by placing a bookshelf against the wall, etc.

What is the Radio Data
System?
Radio Data System (RDS) is a broadcasting
service that allows radio stations to send
additional information along with the regular
program signal. RDS is available only on FM
stations.*
Note
RDS may not work properly if the station you are tuned
in is not transmitting the RDS signal properly or if the
signal is weak.
* Not all FM stations provide RDS service, nor do they
provide the same types of services. If you are not
familiar with the RDS system, check with your local
radio stations for details on RDS services in your
area.
Receiving RDS broadcasts
Simply select a station from the FM band.
When you tune in a station that provides RDS
services, the station name appears in the display.
To check the RDS information
Each time you press DISPLAY, the display
changes cyclically as follows:
Station name* t Frequency t Program type*
t Clock display t Effect status
* If the RDS broadcast is not properly received, the
station name may not appear in the display.

On operating voltage
Before operating the system, check that the operating
voltage of your system 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 system from the wall outlet (mains) if it
is not to be used for an extended period of time. To
disconnect the power cord (mains lead), pull it out by
the plug. Never pull the cord itself.
• Should any solid object or liquid fall into the system,
unplug the system and have it checked by qualified
personnel before operating it any further.
• AC power cord must be changed only at the qualified
service shop.
On placement
• Do not place the system in an inclined position.
• Do not place the system in locations where it is;
– Extremely hot or cold
– Dusty or dirty
– Very humid
– Subject to vibrations
– 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 system heats up during operation, this
is not a malfunction.
• Place the system in a location with adequate
ventilation to prevent heat buildup in the system.
• If you continuously use this system at a high 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 system 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 system will not operate
properly. Remove the disc and leave the system
turned on for about an hour until the moisture
evaporates.
• When you move the system, take out any disc.
If you have any questions or problems concerning your
system, please consult your nearest Sony dealer.
Notes on discs
• Before playing, clean the disc with a cleaning cloth.
Wipe the disc from the center out.
• 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.
• 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.

GB
Cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with mild detergent solution. Do not
use any type of abrasive pad, scouring powder or
solvent such as thinner, benzene or alcohol.
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.
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
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use. Be
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.
Demagnetising the tape heads
Demagnetise the tape heads and the metal parts that
have contact with the tape after every 20 to 30 hours of
use with a separately sold demagnetising cassette. For
details, refer to the instructions of the demagnetising
cassette.
