1. This design of this product contains special hardware and many circuits and components specially or
safety purposes. For continued protection, no changes should be ma de to the original design unless
authorized in writing by the manufacturer. Replacement parts must be identical to those used in the
original circuits. Services should be performed by qualified personnel only.
2. Alterations of the de sign or circuitry of the product should not be made. Any design alterations of the
product should not be made. Any design alterations or a ddition s will void the ma nufacturer`s warranty
and will further relieve the ma nufa cture of responsibility f or personal injury or property da mage re sulting
therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics.
These characteristics are often not evident from visual in spe ction nor can the protection afforded by
them necessarily be obtained by using replacement components rated for higher voltage, wattage,
etc. Replacement parts which have the se special safety characteristics are identified in the Parts List
of Service Manual. Electrical components having such features are identified by shading on the
schematics and by ( ) on the Parts List in the Service Manual. The use of a substitute replacement
which does not have the same safety characteristics as the recommended replacement parts shown
in the Parts List of Service Manual may create shock, fire, or other hazards.
4. The leads in the products are routed a nd dre ssed with ties, clamps, tubings, barriers and the like to be
separated from live parts, high temperature parts, moving parts a nd/or sharp edges for the prevention
of electric shock and fire hazard. When service is required, the original lead routing and dress should
be observed, and it should be confirmed that they have been returned to normal, after re-assembling.
After re-assembling the product, always perform an isolation check on the exposed metal parts of
the product (antenna termin als, knobs, metal cabinet, screw heads, he adphone jack, control shafts,
etc.) to be sure the product is safe to operate without danger of electrical shock. Do not use a line
isolation transformer during this check.
l Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure the
leakage current from each exposed metal parts of the cabinet, particularly any exposed metal part
having a return path to the chassis, to a known good earth ground. Any leakage current must not
exceed 0.5mA AC (r.m.s.)
l Alternate check method
Plug the AC line cord directly into the AC outlet.
Use an AC voltmeter having, 1,000 ohms per volt
or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15
AC-type capacitor between an exposed metal part
and a known good earth ground. Measure the AC
voltage acros s the resi stor with the AC voltmeter.
Move the resistor connection to each exposed
metal part, pa rticularly any exposed metal part
having a return path to the chassis, and meausre
the AC voltage across the resistor. Now, reverse
the plug in the AC outlet andrepeat each
measurement. Voltage measured Any must not
exceed 0.75 V AC (r.m.s .). This corresponds to
0.5 mA AC (r.m.s.).

Warning
1. This equipment ha s been designed a nd manufa ctured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in a ccordance with the releva nt safety standards.
4. It is essential that safety critical components are repla ced by a pproved parts.
5. If mains voltage selector is provided, check setting for local voltage.
In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the “ ” mark
nearby are critical for safety.
When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.
(Except the J and C version)
! CAUTION
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.

Preventing static electricity
1. Grounding to prevent da mage by 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.
2. About the e arth processing for the de struction prevention by static electricity
In the equipment which uses optical pick-up (laser diode), optical pick-up is destroyed by the static
electricity of the work environment.
Be careful to use proper grounding in the area where repairs are being performed.
2-1 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.
2-2 Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
3. Handling the optical pickup
1. 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.)
2. 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.
4. Handling the CD cha nger unit (optical pickup)
1. Do not subject the CD changer 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 CD changer
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.
Attention when traverse unit is decomposed
* Please refer to "Disassembly method" in the text for pick
up and how to detach the CD changer mechanism.
1. Remove the CD changer unit.
2. Disconnect the harness from connector on the CD motor
board.
3. Solder is put up before the card wire is removed from connector
Cn601on the main board a s shown in Fig.1 a nd Fig. 2.
(When the wire is removed without putting up solder, the CD
pick-up assembly might destroy.)
4. Please remove solder after connecting the card wire with
CN601 when you install picking up in the substrate.

Precautions for measurement
1. Apply 30pF and 33kohm to the IF sweeper output
side and 0.082
sweeper input side.
2. The IF sweeper output level should be made as low as
possible within the adjustable range.
3. Since the IF sweeper is a fixed device, there is no
need to adjust this sweeper.
4. Since a ceramic oscillator is used, there is no need to
perform any MPX adjustment.
5. Since a fixed coil is used, there is no need to adjust
the FM tracking.
6.The input and output earth systems are separated. In
case of simultaneously measuring the voltage in both
of the input and output syst ems with an electronic
voltmeter for two cha nnels, theref ore, the e arth should
be connected particularly.
7. In the case of BTL connection amplifier, the minus
terminal of speaker is not for earthing. Therefore, be
sure not to connect any other earth terminal to this
terminal. This system is of an OTL system.

Maintenance of laser pickup
(1) Cleaning the pick up lens
Before you replace the pick up, please try
to clean the len s with a alcohol soaked cotton swab.
(2) Life of the la ser diode
When the life of the la ser diode has expired,
the following symptoms will a ppe ar.
1. The level of RF output (EFM output: a mpli
tude of eye pattern) will below.
Repla cement of laser pickup
(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 chara cteristics of the whole optical block,
do not touch the semi-fixed resistor.
If the la ser power is lower than the specif ied value, the la ser diode is almost worn out, and the laser pickup should
be replaced.
If the semi-fixed resistor would be adjusted when the pickup operates normally, the laser pickup may be damaged due to excessive current.
