Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C
during repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

•Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit. Do
not use such discs.
•A disc with paper or stickers on it.

ROMs, defined by ISO (International Organization
for Standardization).
2) Multi Session
This is a recording method that enables adding of
data using the Track-At-Once method.
Conventional CDs begin at a CD control area called
the Lead-in and end at an area called Lead-out. A
Multi Session CD is a CD having multiple sessions,
with each segment from Lead-in to Lead-out
regarded as a single session.
Notes on CD-R and CD-RW
•Some CD-Rs or CD-RWs cannot be played
on this system depending upon the recording
quality or physical condition of the disc, or
the characteristics of the recording device.
Furthermore, the disc will not play if it has not
been correctly finalized. For more
information, see the operating instructions for
the recording device.
•Discs recorded on CD-R/CD-RW drives may
not be played back because of scratches, dirt,
recording condition or the driver’s
characteristics.
•CD-R and CD-RW discs recorded in packet
write format are not supported.
•CD-R and CD-RW discs that have not ended
by “closing the session” are not supported.
•The system may be unable to play MP3
format files that do not have the “.MP3”
extension.
•Attempting to play non-MP3 format files that
have the “.MP3” extension may result in noise
or malfunction.
•With formats other than ISO9660 Level 1,
Joliet and Romeo, folder names or file names
may not be displayed correctly.
•The following discs take a longer time to start
playback.
–adiscrecorded with complicated tree
structure.
–adisc recorded in Multi Session.
–adisctowhich data can be added (non-
finalized disc).
Music discs encoded with
copyright protection
technologies
This product is designed to playback 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.
Cautions when playing a disc
that is recorded in Multi
Session
•If the disc begins with a CD-DA session, it is
recognized as a CD-DA (audio) disc, and
playback continues until an MP3 session is
encountered.
•If the disc begins with an MP3 session, it is
recognized as an MP3 disc, and playback
continues until a CD-DA (audio) session is
encountered.
•The playback range of an MP3 disc is
determined by the tree structure of files
produced by analyzing of the disc.
•A disc with a mixed CD or CD-Extra format
will be recognized as a CD-DA (audio) disc.

SECTION 1
SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
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.
NOTES ON LASER DIODE EMISSION CHECK
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.
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)
: LEAD FREE MARK
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.
