2. Safety Precaution
(This “SafetyPrecaution” is appliedonlyinU.S.A..)
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use onlymanufacture’srecommended
components for safety.
3. Check the condition of the power cord. Replace ifwear or damage
3

isevident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields etc..
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to ashock hazard.
2.1. Insulation resistance test
1. Unplug the power cord and short the twoprongs of the plug with
ajumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the
jumpered AC plug and each exposed metal cabinet parts, such as
screw heads antenna, control shafts, handlebrackets, etc..
Equipment with antenna terminalsshouldread between 3M -
5.2M to all exposed parts. (Refer to Fig. 2-1.)Equipment without
antenna terminalsshouldread approximatelyinfinityto all
exposed parts. (Refer to Fig. 2-2.)
Note:
Some exposedparts maybe isolatedfromthe chassis bydesign. These will readinfinity.
4. Ifthe measurement isoutside the specified limits, there isa
possibilityof ashock hazard. The equipment shouldbe repaired
and rechecked before itisreturned to the customer.

3. Precaution of Laser Diode
Caution:
Thisunitutilizes aclass 1laser. Invisiblelaser radiation isemitted
from the optical pickup lens when the unitisturn on:
1. Donot look directlyinto the pickup lens.
2. Donot use optical instruments to look at pickup lens.
3. Donot adjust the preset variableresistor on the optical pickup.
4. Donot disassemblethe optical pickup unit.
5. Ifthe optical pickup isreplaced, use the manufacture’sspecified
replacement pickup only.
6. Use of control or adjustment or performance of procedures other
than those specified hereinmayresultinhazardous radiation
exposure.
4. CD and CDR Messages
4.1. SCMS (Serial CopyManagement System)
Due tocopyright and otherconsiderations, the following restriction is nowinplace forCD-R
and CD-RW discs ontowhichthe digital signals of CDs have beencopied.
The digital qualityof CDs and otherdigital media canbe recordedtoCD-R and CD-RW using the
CDR function of this unit. However, it is not possible tomake a second generation digital copy
froma first generation copy. This restriction, knownasSCMS (Serial CopyManagement
System), is intendedtoprevent unlimiteddigital copying inthe interests of artists and other
copyright holders.
This unit is designedtocomplywithSCMS restrictions.
The copyright laws allowrecordings tobe made forthe personal enjoyment of the individual
5

userbut theydo not allowsuchrecordings tobe usedforanyotherpurpose without permission
fromthe rightful ownerof the copyrights.
Notes
-Ifdigital recording of afirst generation digital copyisattempted,
“SCMS PROTECT” isshowninthe information display, and the
recording operation iscanceled.
-Inthe case of synchronized recording operations, Listening Edit
recording and Program Editrecording, when the first-generation
copyisafinalized CD-Ror CD-RWdisc loaded inthe 3-CD
changer, the recording type isautomaticallychanged fromdigital
to analog, and the recording type indicators light accordingly. (If
high-speed dubbing isturned on, itwill be turned off when the
recording type ischanged.)
4.2. CompatibleDisc Formats
The following disc formats canbe usedforrecording inthe CDR.
Inaddition tothe marks shownon the right, the phrases shownbelowortheirequivalent should
alsobe present somewhere on the packaging oraccompanying documentation:
FOR CONSUMER
FOR CONSUMER USE
FOR MUSIC USE ONLY
Discs that cannot be usedforrecording are as follows:
-Discs bearing marks other than those shownabove
-Discs intended for professional use and/or marked
“FORPROFESSIONALUSE ONLY”
-Discs intended for recording computer data
Inaddition tothe twodisc formats shownabove, the following disc format canalsobe playedin
eitherthe 3-CD changerorCDR.

Notes
-The unitcan playback audiodata recorded on CD-G, CD-EXTRA
and CD-Text discs as well, however the text information of CD-
Text discs cannot be displayed.
-IfaCD-Ror CD-RWhas been recorded using apersonal computer,
playback isonlypossibleifthe disc isrecorded inthe CD-Digital
Audioformat.
-You can playCD-Rand CD-RWdiscs recorded inthe musicCD
format.
Some of them, however, maynot be played depending on the disc
characteristics or recording condition.
-Donot use aCD-Ror CD-RWdisc that has been recorded inany
format other than the musicCD format or aCD-RWdisc that has
been used inanyformat other than the musicCD format with this
unit. Using such adisc with thisunitmaycause loudsound to
damage the speakers or cause hearing disorder.
5. Location of Controls
6. Preventing static electricity
Electrostatic discharge (ESD), whichoccurs whenstatic electricitystoredinthe body, fabric,
etc. is discharged, candestroythe laserdiode inthe traverse unit (optical pickup). Take care to
prevent this whenperforming repairs.
6.1. Grounding to prevent damage bystaticelectricity
Static electricityinthe work area candestroythe optical pickup (laserdiode) indevices suchas
CD players.
Be careful touse propergrounding inthe area where repairs are being performed.
6.1.1. Ground the workbench
1. Ground the workbench bylaying conductive material (such as a
conductive sheet) or an iron plate over itbefore placing the
traverse unit(optical pickup) on it. (Refer to Fig. 6-1.)
6.1.2. Ground yourself
1. Use an anti-staticwrist strap to release anystaticelectricitybuilt
up inyour body. (Refer to Fig. 6-1.)

6.1.3. Handling the optical pickup
1. Inorder to maintainqualityduring transport and before
installation, both sides of the laser diode on the replacement
optical pickup are shorted. After replacement, return the shorted
parts to theiroriginal condition.
(Refer to the text.)
2. Donot use atester to check the condition of the laser diode inthe
optical pickup. The tester’sinternal power source can easily
destroythe laser diode.
6.2. Handling the traverse unit(optical pickup)
1. Donot subject the traverse unit(optical pickup) to strong shocks,
as itisasensitive, complex unit.
2. Cut off the shorted part of the flexiblecableusing nippers, etc.
after replacing the optical pickup. For specificdetails, refer to the
replacement procedure inthe text. Remove the anti-staticpin
when replacing the traverse unit. Becarefulnot to take too long a
time when attaching itto the connector.

3. Handlethe flexiblecablecarefullyas itmaybreak when subjected
to strong force.
4. Itisnot possibleto adjust the semi-fixed resistor that adjusts the
laser power. Donot turn it
7. Precautions for Service
[Handling of Traverse Unit and LaserPickup]
1. Donot touch anyperipheral element of the pickup or the actuator.
2. The traverse unitand the pickup are precision devices and
therefore must not be subjected to strong shock.
3. Donot use atester to examine the laser diode. (The diode can
easilybe destroyed bythe internal power supplyof the tester.)
4. To replace the traverse unit, pull out the metal short pinfor
protection from charging.
5. When replacing the pickup, after mounting anew pickup, remove
the solder on the short land which isprovided at the center of the
flexiblewire to open the circuit.
6. Half-fixed resistors for laser power adjustment are adjusted in
pairs at shipment to match the characteristics of the optical block.
Donot change the setting of these half-fixed resistors for laser
power adjustment.
7. New pickup isshorted bysoldering the land which isprovided at
the part nof the flexibleboard on the underside of it.
After completing the rapair, remove the solder to open the circuit.

[Destruction of Traverse Unit and LaserPickup byStatic Electricity]
Laserdiodes are easilydestroyedbystatic electricitychargedon clothing orthe humanbody.
Before repairing peripheral elements of the traverse unit orpickup, be sure totake the following
electrostatic protection:
1. Wear an antistaticwrist wrap.
2. With aconductive sheet or asteel plate on the workbench on
which the traverse unitor the pickup isto be repaired, ground the
sheet or the plate.
3. After removing the flexiblewire from the connector (CN601), short-
circuitthe flexiblewire bythe metal clip.
4. Short-circuitthe laser diode bysoldering the land which is
provided at the center of the flexiblewire for the pickup.
After completing the repair, remove the solder to open the circuit.
Please referto"Fig.4" of "Disassemblymethod <Changermechanismunit>" fordetails.
