UNLEADED  SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with 

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.
•  Unleaded solder melts at a temperature about 40 °C higher 

than ordinary solder.

 

Ordinary soldering irons can be used but the iron tip has to be 
applied to the solder joint for a slightly longer time.

 

Soldering irons using a temperature regulator should be set to 
about 350 °C.
Caution:  The printed pattern (copper foil) may peel away if the 

heated tip is applied for too long, so be careful!

• Strong 

viscosity

 

Unleaded solder is more viscous (sticky, less prone to fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.

•  Usable with ordinary solder
 

It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.

The laser diode in the optical pick-up block may suffer electrostat-
ic 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 fl exible board is easily damaged and should be handled with 
care.

NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

s

] button, press the [

A

] button until “UN-

LOCKED” displayed on the fl uorescent indicator tube (around 
5 seconds).

Note:  When “LOCKED” is displayed, the tray lock is not released by

RELEASING  THE  DEMO  PLAY  LOCK
Releasing Procedure:
1.  Press the [

?/1

] button to turn on the system.

2.  Press the [FUNCTION] button repeatedly to select “DVD”.
3.  While pressing the [

s

] button, press the [

H

] button until 

“DEMO OFF” displayed on the fl uorescent indicator tube 
(around 5 seconds).

• CD-ROM recorded in PHOTO CD format
• Data part of CD-Extra

* Except for United Kingdom and North American models.

DVD that does not contain MP3 files or JPEG image files, or DivX video 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.

• 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 pl ayed 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.
