Notes on CD-R and CD-RW  
Music discs encoded with  
copyright protection  
technologies  
• This system can play back 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.  
This product is designed to play back 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.  
• Discs recorded on CD-R/CD-RW drives may  
not be played back because of scratches, dirt,  
recording condition or the driver’s  
characteristics.  
Note on DualDiscs  
Cautions when playing a disc  
that is recorded in Multi  
Session  
This product is designed to play back discs that  
conform to the Compact Disc (CD) standard.  
A DualDisc is a two sided disc product which  
mates DVD recorded material on one side with  
digital audio material on the other side. Please  
be aware that the audio side of a DualDisc may  
not be played back on this product because these  
discs do not conform to the CD standard.  
• This system can play back Multi Session discs  
when an MP3 audio track is contained in the  
first session. Any subsequent MP3 audio  
tracks recorded in later sessions can also be  
played back.  
“DualDisc” is a trademark of the Recording  
Industry Association of America (RIAA).  
• When you play back Multi Session discs with  
different formats for each session, the format  
of the first session is recognized as the disc  
type. Tracks in the second and subsequent  
sessions are played back if they are the same  
formats as the first session.

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 system.  
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.  
Additional Information  
Precautions  
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.  
• 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.  
On safety  
• The system is not disconnected from the AC power  
source (mains) as long as it is connected to the wall  
outlet, even if the system 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.  
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.  
• 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.  
• 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 system. When this occurs, it may not  
be possible to remove the disc, and may also cause  
this system 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.  
• 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 system or speakers on  
surfaces that have been specially treated (with wax,  
oil, polish, etc.) as staining or discoloration of the  
surface may result.  
– 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 back on this system.  
Attempting to do so may damage the system. Do not  
use such discs.  
On heat build-up  
• Although the system heats up during operation, this  
is not a malfunction.  
• Place the system in a location with adequate  
ventilation to prevent heat build-up in the system.  
• If you continuously use this system at a large volume,  
the cabinet temperature of the top, side and bottom  
rises considerably. To avoid burning yourself, do not  
touch the cabinet.  
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 prevent a malfunction, do not cover the  
ventilation hole for the cooling fan.
