PRECAUTIONS FOR USING LEAD-FREE SOLDER

1.Employing lead-free solder

"MAIN, POWER, DISPLAY, AUDIO IN, CD, 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.

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 wet ability, 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 sand paper.
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.

Setting of Withstanding Voltage Tester and set.

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

[1] Notes On Schematic Diagram

•

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 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,

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.

( ) indicates the record state.

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.
