1.1Safety Precautions
SECTION 1
PRECAUTIONS
!
!
Burrs formed during molding may be left over on some parts of the chassis. Therefore,
pay attention to such burrs in the case of preforming repair of this system.
Please use enough caution not to see the beam directly or touch it in case of an
adjustment or operation check.
(No.MA143)1-3

1.2Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser
diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.2.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption)
Anti-static wrist strap
1M
Conductive material
(conductive sheet) or iron plate
(3) Handling the optical pickup
• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical
pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily
destroy the laser diode.
1.3Handling the traverse unit (optical pickup)
(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the
replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a
time when attaching it to the connector.
(3) Handle the flexible cable carefully as it may break when subjected to strong force.
(4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.
1.4Attention when traverse unit is decomposed
*Please refer to "Disassembly method" in the text for the CD pickup unit.
• Apply solder to the short land before the flexible wire is disconnected from the connector on the CD pickup unit.
(If the flexible wire is disconnected without applying solder, the CD pickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land after connecting the flexible wire.

5.6Maintenance of laser pickup
(1) Cleaning the pick up lens
Before you replace the pick up, please try to clean the lens
with a alcohol soaked cotton swab.
(2) Life of the laser diode
When the life of the laser diode has expired, the following
symptoms will appear.
• The level of RF output (EFM output: amplitude of eye
pattern) will be low.
5.7Replacement of laser pickup
Turn of the power switch and, disconnect the
power cord.
Replace the pickup with a normal one. (Refer
to "Removing the pickup unit" on the previous page.)
Is RF output
1.3 0.4Vp-p?
NO
Replace it.
YES
OK
(3) Semi-fixed resistor on the APC PC board
The semi-fixed resistor on the APC printed circuit board
which is attached to the pickup is used to adjust the laser
power.Since this adjustment should be performed to match
the characteristics of the whole optical block, do not touch
the semi-fixed resistor.
If the laser power is lower than the specified value, the laser diode is almost worn out, and the laser pickup should
be replaced. If the semi-fixed resistor is adjusted while the
pickup is functioning normally, the laser pickup may be
damaged due to excessive current.
Plug the power cord in, and turn the power on.
At this time, check that the laser emits for about
seconds and the objective lens moves up and down.
Note: Do not observe the laser beam directly.
Play a disc.
Check the eye-pattern at
RF test point.
Finish.

ADDITIONAL INFORMATION
Playing a CD-R or CD-RW
• Use only “finalized” CD-Rs or CD-RWs.
• This unit can play back only the files of the
same type which is first detected if a disc
ENGLISH
includes both audio CD (CD-DA) files and MP3
files.
• This unit can play back multi-session discs;
however, unclosed sessions will be skipped
while playing.
• Some CD-Rs or CD-RWs may not play back on
this unit because of their disc characteristics,
and for the following causes:
– Discs are dirty or scratched.
– Moisture condensation on the lens inside the
unit.
– The pickup lens inside the unit is dirty.
– CD-R/CD-RW on which the files are written
with “Packet Write” method.
– There are improper recording conditions
(missing data, etc.) or media conditions
(stain, scratch, warp, etc.).
• CD-RWs may require a longer readout time
since the reflectance of CD-RWs is lower than
that of regular CDs.
• Do not use following CD-Rs or CD-RWs:
– Discs with stickers, labels, or protective seal
stuck to the surface.
– Discs on which labels can be directly printed
by an ink jet printer.
Using these discs under high temperatures or
high humidity may cause malfunctions or
damage to discs.
Playing an MP3 disc
• This unit can play back MP3 files with the
extension code <.mp3> (regardless of the
letter case—upper/lower).
• This unit can show the names of albums,
artists (performer), and ID3 Tag (Version 1.0,
1.1, 2.2, 2.3, or 2.4) for MP3 files.
