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.

ISO9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are several specification levels. In Level 1,
file names must be in the 8.3 format (no more than
eight characters in the name, no more than three
characters in the extension) and in capital letters.
Folder names can be no longer than eight characters.
There can be no more than eight nested folder
levels. Level 2 specifications allow file names and
folder names up to 31 characters long. Each folder
can have up to 8 trees.
For Joliet in the expansion format (file and folder
names can have up to 64 characters) make sure of
the contents of the writing software, etc.

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.
CD-Extra: This format records audio (audio CD
data) on the tracks in session 1 and data on the tracks
in session 2.
Mixed CD: This format records data on the first
track and audio (audio CD data) on the second and
subsequent tracks of a session.

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

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
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
