SAFETY PRECAUTION FOR SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements.
However, the following precautions must be observed during servicing to protect your eyes against 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.
VOLTAGE SELECTION
Before operating the unit on mains, check the preset voltage. If the voltage is different from your local voltage, adjust the voltage
as follows.
Turn the selector with a screwdriver until the appropriate voltage number appears in the window (110V,127V,220V or 230V 240V AC).

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"VCD 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 fixingthe PWBsoldered with the lead-free solder,apply lead-freewire solder. Repairing with conventionallead wiresolder
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 off or the maximum heat-resistance temperature of parts may be exceeded,
remove the bit from the PWB as soon as you confirm the steady soldering 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.

3. CD SECTION
• Adjustment
Since this CD system incorporates the following automatic adjust-
ment functions, readjustment is not needed when replacing the
pickup. Therefore, different PWBs and pickups can be combined
freely.
Each time a disc is changed, these adjustments are performed
automatically. Therefore, playback of each disc can be performed
under optimum conditions.
Items adjusted automatically
1) Offset adjustment (The offset voltage between the head amplifier
output and the VREF reference voltage is compensated inside the
IC.)
3) Gain adjustment (The gain is compensated inside the IC so that the
loop gain at the gain crossover frequency will be 0 dB.)
* Focus gain adjustment
* Tracking gain adjustment

•Resistor:
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 microfarad. 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 th e one measured by Digital Multimeter between such a section and the chassis with no signal given.
1. In the tuner section,
indicates AM
indicates FM stereo
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.
• Parts marked with “ ” () are important for
maintaining the safety of the set. Be sure to replace these parts
with specified ones for maintaining the safety and performance of
the set.
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 section does not operate even after the above step is taken, check the following items.
Remove the cabinet and follow the trouble shooting instructions.
"Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens. Before attempting
any adjustment make 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
brush on the CD cleaner disc which has the mark next to it.
2.
Place the CD cleaner disc onto the CD disc tray with the brush side down,then
press the play button.
3.
You will hear music for about 20 seconds and the CD player will automatically stop.
If it still play continuously, press the stop button.
Cleaning fluid
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.
All rights reserved. Unauthorized duplicating, broadcasting and renting this product
is prohibited by law.
Cleaner disc
2. When a CD cannot be played
2.1. "E-CD01" is displayed.
1) Check the power to IC1 (LC78637E), the presence of the clock signal (16.9344 MHz) and the status of the RESET terminal (pin 66 on IC1).
2) Does the pickup move to the PICKUP-IN Switch (SW1A) position?
If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).
2.2. Pressing the CD operation key is accepted, but playback does not occur.
1) Focus-HF system check
2) Tracking system check
3) Spin system check
4) PLL system check
