(When letters/numbers appear in the display)
When the self-diagnosis function is activated to prevent the system from malfunctioning, a 5-character service 
number (e.g., C 13 50) with a combination of a letter and 4 digits appears on the screen and the front panel display. 
In this case, check the following table.
When displaying the version number on the screen
When you turn on the system, the version number [VER.X.XX] (X is a number) may appear on the screen. Although this 
is not a malfunction and for Sony service use only, normal system operation will not be possible. Turn off the system, and 
then turn on the system again to operate.

Note about CDs/DVDs
The system can play CD-ROMs/CD-Rs/CD-RWs 
recorded in the following formats:
– audio CD format.
– video CD format.
– MP3 audio tracks, JPEG image files, and DivX 
video files of format conforming to ISO 9660 Level 
1/Level 2, or its extended format, Joliet.

RWs/DVD+Rs/DVD-Rs recorded in the following 
formats:
– MP3 audio tracks, JPEG image files and DivX 
video files of format conforming to UDF (Universal

• CD-ROMs/CD-Rs/CD-RWs other than those 
recorded in the formats listed left.
 
 
• CD-ROMs recorded in PHOTO CD format.
• Data part of CD-Extras.
• DVD Audios.
• DVD-RAMs.
Notes about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/
DVD+RW
In some cases, CD-R/CD-RW/DV D-R/DVD-RW/DVD+R/
DVD+RW cannot be played on this system due to the 
recording quality or physical condition of the disc, or the 
characteristics of the recording device and authoring 
software.
The disc will not play if it has not been correctly finalized. 
For more information, see the operating instructions for the 
recording device.
Note that discs created in the Packet Write format cannot be 
played.
Note that some playback functions may not work with some 
DVD+Rs/DVD+RWs, even if they have been correctly 
finalized. In this case, view the disc by normal playback. 
Also some DATA  CDs/DAT A DVDs created in Packet 
Write format cannot be played.
Music discs encoded with copyright protection 
technologies
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.
Note on DualDisc
A DualDisc is a two sided disc product which mates DVD 
recorded material on one side with digital audio material on 
the other side. However, since the audio material side does 
not conform to the Compact Disc (CD) standard, playback on 
this product is not guaranteed.
About Multi Session CD
• This system can play Multi Session CDs 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.
• This system can play Multi Session CDs when a 
JPEG image file is contained in the first session. 
Any subsequent JPEG image files recorded in later 
sessions can also be played back. 
• If audio tracks and images in music CD format or 
video CD format are recorded in the first session, 
only the first session will be played back.
About the Super Audio CD
Super Audio CD is a new high-quality audio disc 
standard where music is recorded in the DSD (Direct 
Stream Digital) format (conventional CDs are 
recorded in the PCM format). The DSD format, using 
a sampling frequency 64 times higher than that of a 
conventional CD, and with 1-bit quantization, 
achieves both a wide frequency range and a wide 
dynamic range across the audible frequency range, 
and so provides music reproduction extremely faithful 
to the original sound.
Types of Super Audio CDs
There are two types of discs, depending on the Super 
Audio CD layer and CD layer combination.
• Super Audio CD layer: A high-density signal 
layer for Super Audio CD
• CD  layer*
1
: A layer that is readable by a 
conventional CD player
*1 You can play the CD layer on a conventional CD player.
*2 Since both layers are on one side, it is not necessary to turn the 
disc over.
*3 To select a layer, see “Selecting a playback layer for a Super 
Audio CD (Super Audio CD only)”. 
Region code
You r system has a region code printed on the back of 
the unit and will only play DVDs labelled with the 
same region code.
DVD VIDEOs labelled 
 will also play on this 
system.
If you try to play any other DVD VIDEO, the message 
[Playback prohibited by area limitations.] will appear 
on the TV screen. Depending on the DVD VIDEO, no 
region code indication may be given even though 
playing the DVD VIDEO is prohibited by area 
restrictions.
Note on playback operations of DVDs and 
VIDEO CDs
Some playback operations of DVDs and VIDEO CDs 
may be intentionally set by software producers. Since 
this system plays DVDs and VIDEO CDs according to 
the disc contents the software producers designed, 
some playback features may not be available. Also, 
refer to the instructions supplied with the DVDs or 
VIDEO CDs.
