SECTION 1
SERVICING NOTES
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
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
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.
REGION CODE
This system is used to protect software copyrights.
The region code is located on the bottom of the unit, and only DVDs
labeled with an identical region code can be played on this unit.
DVDs labeled ALL can be also played on this unit.
If you try to play any other DVD, the message "Can not play" will
appear on the monitor screen. Depending on the DVD, no region
code may be labeled even though playing the DVD is prohibited by
area restrictions.

Format of discs
DVD
A DVD contains both audio and visual data.
A 12-cm disc can hold 7 times the amount of
data contained in a CD-ROM, which equals
to 4 consecutive hours of playing time (8
hours for double-sided discs). DVDs are
divided into 4 types: single sided single layer,
single sided double layer, double sided single
layer, and double sided double layer.
Video CD (VCD)
A Video CD can contain both audio and
visual data on a disc with the same size as a
regular Audio CD. The playing time is 74
minutes for a standard 12-cm CD.
Audio CD
An Audio CD containing audio data. The
playing time is 74 minutes for a standard 12-
cm CD.
CD-Recordable (CD-R)
With a CD-R, you can edit audio data. You
can write information on a CD-R only once.
CD-Rewritable (CD-RW)
With a CD-RW, you can edit audio data. You
can write information on a CD-RW again and
again.
CD-Extra
A CD-Extra has two sections (sessions) for
audio and data respectively. You can only
play the section of audio on this unit.
Notes
· You can play DVD-Rs/DVD-RWs, DVD+Rs/
DVD+RWs and CD-Rs/CD-RWs designed for audio
with this unit. However, depending on the recorded
conditions, you cannot play some discs.
· You cannot play CD-Rs/CD-RWs, DVD-Rs/DVD-
RWs or DVD+Rs/DVD+RWs that are not finalized.
· Discs created in Packet Write format cannot be played.
· The discs listed below cannot be played on this unit:

NOTE WHEN REPLACING CHASSIS (MAIN) ASSY OR OPEN/CLOSE MECHANISM DECK (DB-M03)
The shape of CHASSIS (MAIN) ASSY has been partially changed in the midway of production.
Along with this modification, two screws that secure the Hook Assy and Front Panel have been also changed. Be sure to replace two screws
(Refer to the "EXPLODED VIEWS 6-1. FRONT PANEL SECTION Ref. No. 6" (See page 85)) that secure the Hook Assy and Front Panel
simultaneously when replacing the CHASSIS (MAIN) ASSY or OPEN/CLOSE MECHANISM DECK (DB-M03) of the set having the
