PRECAUTIONSFOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
Example:
Indicateslead-free solder of tin, silver and copper.
Lead-free wire solder for servicing
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.
Asthe melting point of lead-free solder (Sn-Ag-Cu) ishigher than the lead wire solder by 40°C, we recommend
youto use adedicated soldering bit, if youare 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
Asthe melting point of lead-free solder (Sn-Ag-Cu) isabout 220°C which ishigher than the conventional lead
solder by 40°C, and as it has poor solder wet ability, youmay 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 partsmay be exceeded, remove the bit from the PWB as soon as youconfirm the steady
soldering condition.
Lead-free solder containsmore 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 adifferent type of solder stayson the tip of the soldering bit, it isalloyed with lead-free solder. Clean the bit
after every use of it.
When the tip of the soldering bit isblackened during use, file it with steel wool or fine sand paper.
Be careful when replacing partswith polarity indication on the PWB silk.

CHAPTER 1. GENERAL DESCRIPTION
Before returning the audio product to the user, perform
the following safety checks.
2. Inspect all protective devicessuch as insulating
materials, cabinet, terminal board, adjustment and
compartment coversor shields, mechanical insulators
etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
*Plug the AC line cord directly into a120 volt AC outlet.
*Using two clip leads, connect a1.5k ohm, 10 watt
resistor paralleled by a0.15µF capacitor in series
with all exposed metal cabinet partsand aknown
earth ground, such as conduit or electrical ground
connected to earth ground.
*Use aVTVM or VOM with 1000 ohm per volt, or
higher, sensitivity to measure the AC voltage drop
across the resistor (See diagram).
* Connect the resistor connection to all exposed metal
partshaving areturn path to the chassis(antenna,
metal cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All check must be repeated with the AC line cord plug
connection reversed.
Any reading of 0.3volt RMS (thiscorrespondsto 0.2
milliamp. AC.) Or more isexcessive and indicatesa
potential shock hazard which must be corrected before
returning the audio product to the owner.
[2] Important Service Notes(for U.S.A only)
BEFORE RETURNING THE AUDIO PRODUCT

[1] Important Service Safety Precaution
CAUTION : “These servicing instructionsare for use by qualified service personnel only. To reduce
the risk of electric shock do not perform any servicing other than that contained in the operating
instructionsunless you are qualified to do so”.
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.

CHAPTER 2. ADJUSTMENTS
[1] CD Section
•Adjustment
Since this CD system incorporates the following
automatic adjustment 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)
* Focus offset adjustment
* Tracking offset adjustment
2) Tracking balance adjustment
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

CHAPTER 5. FLOWCHART
[1] Troubleshooting
1. When the CD doesnot 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 section does not operate even after the above step is taken, check the
following items.
Remove the cabinet and follow the troubleshooting 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.
2. When a CD cannot be played
2.1. Pressingthe CD operation key isaccepted, but playback doesnot occur.
1) Focus-HF system check
2) Tracking system check
3) Spin system check
4) PLL system check
Parts code
1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ
HOW TO USE
CAUTION
Cleaning fluid
Cleaner disc
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.
Place the CD cleaner disc onto the CD disc tray with the brush side down, then
press the play button.
You will hear music for about 20 seconds and the CD player will automatically stop.
If it still play continuously, press the stop button.
1.
2.
3.
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.

Pins 50, 51, 48, 49 (55 ~ 62) on IC1.
Check the laser diode driver Q4 peripheral circuit.

(2) Trackingsystem check.
If the waveform shown in Figure 4 appears and soon after NO
DISC appears ?
Check the TE waveform at pin 63 on IC1.

No
Yes
A normal jump operation cannot be completed or the begining of
the track cannot be found.
Check the around pin 49 on IC1.
Yes
"Initialization" is not possible.
No
When a disc is loaded, start play operation.
The RF waveform is normal, but the TOC data cannot be read.
Check the PLL waveform. (Figure 6)
Check around pins 73 ~ 76 on IC1.
Data cannot be read. Check the VCO - PLL (Pin no. 73 ~ 76)
on IC1 system.
(3) Spin system check.
(4) PLL system check.
Press the OPEN/CLOSE switch without inserting a disc, and
then try starting the play operation.
1. The turntable rotates a little ?
(Waveform drawing Figure 5) Yes
2. The turntable does not rotate.
The spin driver circuit is OK.
Check around pin 50 on IC1, pins 1 and 2 on CNP2.
