PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"MAIN, POWER, DISPLAY, AUDIO IN, CD PWB" of this model employs lead-free solder.
The LF symbol indicates lead-free solder, and is attached on the PWB and service manuals. The alphabetical character
following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire
solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you to
use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our
service station or service branch in your area.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder
by 40°C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. However, since the land may be peeled of for the maximum heat-resistance temperature
of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady solder ing condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on
and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

Safety Precaution For Service Manual
WARNINGS
THE AEL (ACCESSIBLE EMISSION LEVEL) OF LASER POWER OUTPUT FOR THIS MODEL IS SPECIFIED TO
BE LOWER THAN CLASS I REQUIREMENTS. HOWEVER, THE FOLLOWING PRECAUTIONS MUST BE OBSERVED
DURING SERVICING TO PROTECT YOUR EYES AGAINTS EXPOSURE TO THE LASER BEAM.
1- WHEN THE CABINET HAS BEEN REMOVED, THE POWER IS TURNED ON WITHOUT A COMPACT DISC,
AND THE PICKUP IS ON A POSITION OUTER THAN THE LEAD-IN POSITION, THE LASER WILL LIGHT FOR
SEVERAL SECONDS TO DETECT A DISC.
DO NOT LOOK INTO THE PICKUP LENS.
2- THE LASER POWER OUTPUT OF THE PICKUP INSIDE THE UNIT AND REPLACEMENT SERVICE PARTS
HAVE ALREADY BEEN ADJUSTED PRIOR TO SHIPPING.
3- NO ADJUSTMENT TO THE LASER POWER SHOULD BE ATTEMPTED WHEN REPLACING OR SERVICING
THE PICKUP.
4- UNDER NO CIRCUMSTANCES LOOK DIRECTLY INTO THE PICKUP LENS AT ANY TIME.
5- CAUTION - USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
This product is classified as a CLASS 1 LASER PRODUCT.
[2] Important Service Notes (For U.K. Only)
Before returning the unit to the customer after completion of a repair or adjustment it is necessary for the following withstand voltage test to be
applied to ensure the unit is safe for the customer to use.

2. CHANGER MECHANISM SECTION
Perform steps 1, 2, 7 and 8 of the disassembly method
to remove the CD changer mechanism.
2.1 How to remove CD Disc (See Fig. 1-4)
1. When CD is at play position (Figure 1), rotate
reduction gear C clock-wise as shown in Figure 2
until disc tray is at stock position, then rotate further
to eject the disc tray so that CD can be removed
from the tray.

2. In another case, if CD mechanism is at tray No.1
play position and to remove CD located in tray No.3,
the procedure is as follows:
If the gear up down board is located at tray No.1
position, then rotate gear clock-wise until it is at
stock postiiton. Rotate reduction gear D clockwise
(Figure 3) to move the CD mechanism to tray No.3
position. This is confirmed by checking the gear up
down board position by the marking as indicated on
the main chassis as shown in Figure 4.

To differentiate the units of resistors, such symbol
as K and M are used: the symbol K means 1000
ohm and the symbol M means 1000 kohm and the
resistor without any symbol is ohm-type resistor.
Besides, the one with “Fusible” is a fuse type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used:
this symbol P means pico-farad and the unit of the
capacitor without such a symbol is micr ofarad. As to
electrolytic capacitor, the expression “capacitance/
withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board
for this model are subject to change for improvement without prior notice.
• The indicated voltage in each section is the one
measured by Digital Multimeter between such a
section and the chassis with no signal given.
1. In the tuner section,

2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.

4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.

CHAPTER 7. FLOWCHART
[1] Troubleshooting
1. When the CD does not function
The CD section may not operate when the objective lens of the optical pickup is dirty. Clean the objective lens, and
check the playback operation. When this sec tion does not operate even af ter the abo ve step is t ak en, che ck the fo llowing items.
Remove the cabinet and follow the trouble shooting instructions.
"Track skipping and/or no T OC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser
pickup lens. Before attempting any adjustmen t ma ke certain that the lens is clean. If not, clean it as mentioned below."
Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.
Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the
1.
brush on the CD cleaner disc which has the mark next to it.
Place the CD cleaner disc onto the CD disc tray with the brush side down, then
2.
press the play button.
You will hear music for about 20 seconds and the CD player will automatically stop.
3.
If it still play continuously, press the stop button.
CAUTION
The CD lens cleaner should be effective for 30-50 operations, however if the
brushes become worn out earlier then please replace the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft
cloth.
Do not drink the cleaner fluid or allow it contact with the eyes. In the event of this
happening then drink and / or rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD players or on computer CD-ROM
drives.
