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 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.

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.

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.

• 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.

Your  system has a region code printed on the 
rear of the unit and will only play DVDs labeled 
with the same region code.

DVD VIDEOs 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 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.

The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

The disc slot lock function for the antitheft of an demonstration
disc in the store is equipped.

1. Press the  ?/1  button to turn the set on.
2. Press the [FUNCTION] button to set DVD function.
3. Insert a disc.
4. Press the  

x  

stick and the  

A 

 button simultaneously for five

seconds.

5. The message “LOCKED” is displayed and the slot is locked.

1. Press the  

x  

stick and the  

A 

 button simultaneously for five

seconds again.

2. The message “UNLOCKED” is displayed and the slot is

unlocked.

When “LOCKED” is displayed, the slot lock is not released by
turning power on/off with the  ?/1  button.

Note on DMB12 board replacement
New part of EEP ROM (IC103, IC706) on the DMB12 board cannot
be used. Therefore, if the mounted DMB12 board (A-1206-260-A)
is replaced, exchange new EEP ROM (IC103, IC706) with that used
before the replacement.

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

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 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.

C 13

The disc is dirty.

,Clean the disc with a soft cloth 

C 31

The disc is not inserted correctly.

,Restart the system, then re-insert 

the disc correctly

XX

(xx is a number)

To prevent a malfunction, the 
system has performed the self-
diagnosis function.

,Contact your nearest Sony 

dealer or local authorized Sony 
service facility and give the 5-
character service number.

Example: E 61 10
