NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
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.
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 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.
NOTE OF REPLACING THE IC1103 ON THE MAIN
BOARD
IC1103 on the MAIN board cannot exchange with single. When
this part is damaged, exchange the entire mounted board.

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.
Notes on CD-R/CD-RW playback
Discs recorded on CD-R/CD-RW drives may not be played back because
of scratches, dirt, recording condition, or the drive's characteristics.
Besides, the discs, which are not yet finalized at the end of recording,
cannot be played back. In these cases, "Reading" will remain or
"Cannot Play" will appear on the display.
Note on DTS-CDs
DTS signals are output from the DIGITAL OUT (CD) jacks only.
The DTS signals must be decoded on a DTS-compliant digital device to
be listened to.
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.
Note on DSD Discs
A DSD Disc is a disc recorded in the DSF file format.
This player can play DSF files that you have recorded on DVD-ROM
compatible DVD-R, DVD-RW, DVD+R and DVD+RW discs. For details
on DSD Discs.
