PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing 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
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 fines and 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.
