“DVD-RW,” “DVD+RW,” “DVD+R,”“DVD VIDEO,” and the “CD” logos are trademarks.
The system cannot play the following discs:
• CD-ROM/CD-R/CD-RW other than those recorded in the formats listed
• CD-ROM recorded in PHOTO CD format
• Data part of CD-Extra
• CD Graphics disc
• DVD Audio
• DATA DVD that does not contain MP3 files or JPEG image files
• DVD-RAM
Also, the system cannot play the following discs:
• A DVD VIDEO with a different region code
• A disc that has a non-standard shape (e.g., card, heart)
• A disc with paper or stickers on it
• A disc that has the adhesive of cellophane tape or a sticker still left on it
In some cases, CD-R/CD-RW/DVD-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, refer to the operating 
instructions for the recording device.
Note that some playback functions may not work with some DVD+RWs/DVD+Rs, even if they have 
been correctly finalized. In this case, view the disc by normal playback. Also some DATA CDs/DATA 
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 DualDiscs
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.
Example of discs that the system cannot play
Note about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/DVD+RW
• This system can play a Multi Session CD when an MP3 file is contained in the first session. Any 
subsequent MP3 files recorded in later sessions can also be played back.
• This system can play a Multi Session CD 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 MP3 files and JPEG image files in music CD format or video CD format are recorded in the first 
session, only the first session will be played back.
Your system has a region code printed on the rear of the unit and will only play a DVD labeled with 
the same region code.
A DVD VIDEO labeled 
 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.
Some playback operations on a DVD or VIDEO CD may be intentionally set by software producers. 
Since this system will play a DVD or VIDEO CD according to the disc contents the software producers 
designed, some playback features may not be available. Be sure to read the operating instructions 
supplied with the DVD or VIDEO CD.
