PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"MAIN, POWER, DISPLAY, HEADPHONE, USB, iPod, REFRESH 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 alphabetic 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 convention 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 recommen you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or solderin 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 sand paper. Be careful when replacing parts with polarity indication on the PWB silk.

CHAPTER 1. GENERAL DESCRIPTION
[1] 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.

CHAPTER 5. 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 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
DESCRIPTION POSITION
• 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 A M indicates FM stereo
2. 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.
