PRECAUTIONS FOR USING LEAD-FREE SOLDER
1.Employing lead-free solder
"MAIN, POWER, DISPLAY/TAPE, SERVO, iPod, FRONT SPEAKER LED, SUBWOOFER LED 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.
Examples:
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 solder ing 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
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.

[2] Important Service Notes (for U.S.A only)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads
are not pinched or that hardware is not lodged
between
the chassis and other metal parts in the
audio product.
2. Inspect all protective devices such as insulating
materials, cabinet, terminal board, adjustment and
compartment covers or 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 a 120 volt AC
*
outlet.
Using two clip leads, connect a 1.5k ohm, 10
*
watt resistor paralleled by a 0.15µF capacitor in
series with all exposed metal cabinet parts and
a known earth ground, such as conduit or
electrical ground connected to earth ground.
Use a VTVM 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 parts having a return path to the chassis
(antenna, metal cabinet, screw heads, knobs and
control shafts, escutcheon, etc.) and measure the
AC voltage drop across the resistor.

Any reading of 0.3 volt RMS (this corresponds to 0.2

potential shock hazard which must be corrected before
returning the audio product to the owner.

Note:
After removing the connector for the optical pickup from the connector,
wrap the conductive aluminium foil around the front end of the connector
so as to protect the optical pickup from electrostatic damage.
• 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".

CHAPTER 7. FLOWCHART
[1] Troubleshooting
1. When the CD does not function
The CD section may not operate when the objectiv e 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.
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.
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.
