This system conforms to Ver. 1.1 and Ver. 2.0 of 
VIDEO CD standards. You can enjoy two kinds 
of playback depending on the disc type.
About Multi Session CD

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.
Region code
Your system has a region code printed on the 
back of the unit and will only play DVDs labeled 
with the same region code.
DVDs labeled 
 will also play on this system.
If you try to play any other DVD, the message 
[Playback prohibited by area limitations.] will 
appear on the TV screen. Depending on the 
DVD, no region code indication may be given 
even though playing the DVD is prohibited by 
area restrictions.
Examples of discs that the 
system cannot play
The system cannot play the following discs:
• CD-ROMs (except for extension “.MP3,” 
“.JPG,” or “.JPEG”)
• CD-Rs/CD-RWs other than those recorded in 
the following formats:

Notes about CD-R/CD-RW/DVD-R/DVD-RW 
(Video mode)/DVD+R/DVD+RW
In some cases, CD-R/CD-RW/DVD-R/DVD-RW 
(Video mode)/DVD+R/DVD+RW cannot be played 
on this player 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.
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 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.

other intellectual property rights. Use of this 
copyright protection technology must be 
authorized by Macrovision, and is intended for

On handling discs
• To keep the disc clean, handle the disc by its 
edge. Do not touch the surface.
• Do not stick paper or tape on the disc.
• Do not expose the disc to direct sunlight or 
heat sources such as hot air ducts, or leave it in 
a car parked in direct sunlight as the 
temperature may rise considerably inside the 
car.
• After playing, store the disc in its case.
On cleaning
• Before playing, clean the disc with a cleaning 
cloth.
Wipe the disc from the center out.
• Do not use solvents such as benzine, thinner, 
commercially available cleaners, or anti-static 
spray intended for vinyl LPs.
This system can only play back a standard 
circular disc. Using neither standard nor circular 
discs (e.g., card, heart, or star shape) may cause 
a malfunction.
Do not use a disc that has a commercially 
available accessory attached, such as a label or 
ring.
