PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
Example:
Indicates lead-free solder of tin, silver and copper.

"MAIN, iPOD, MICOM, CONTROL, KEY, AUDIO PRO, RE-FLASH MICOM, SUB, LED L-CH, LED R-CH 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.
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 nto 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 sand paper.
Be careful when replacing parts with polarity indication on the PWB silk.

CHAPTER 1. GENERAL DESCRIPTION
(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.
All check must be repeated with the AC line cord plug
connection reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2
milliamp. AC.) Or more is excessive and indicates a
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 instructions are 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
instructions unless 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.
CAUTION: FOR CONTINUED
PROTECTION AGAINST FIRE
HAZARD, REPLACE ONLY WITH
SAME TYPE F800, 630mA, 125V/
F801 5A, 125V FUSES.

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 resis-
tor 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 the one
measured by Digital Multimeter between such a
section and the chassis with no signal given.
1. In the tuner section,
indicates FM stereo
•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.
