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 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.

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 viscou-s (sticky, less prone to flow)
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.

• Data part of CD-Extras

• DVD Audios

• Super Audio CD

• DATA  DVDs that do not contain MP3 audio 

tracks or JPEG image files

• DVD-RAMs

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, 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 
DAT A CDs/DAT A 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.

You r 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. Be sure to read the 
operating instructions supplied with the DVDs 
or VIDEO CDs.
