PRECAUTIONS FOR USING LEAD-FREE SOLDER

1. Employing lead-free solder

"MAIN,DISPLAY,POWER,GAME INPUT,SPEAKER,CD SERVO,CD MOTOR(PWB ONLY),CD CHANGER MOTOR

B ONLY), SUB WOOFER SPEAKER LED,SUB WOOFER AMP,PRIMARY POWER,LED

(PW FLASHING,JACK,VOLUME,POWE

The LF symbol indicates lead-free solder, and is attached on the PWB and service manuals.The alphabetical characte

Example:

r 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 conventiona

l 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, were commen solderin

d you to use a dedicated soldring bit,if you are not familiar with how to obtain lead-free wire solder or

g 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

r by 40 C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the

solde

B for extended period of time. However, since the land may be peeled off or the maximum heat-resistance

PW temperatur solderin Lead-fre

e of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady

g condition.

e 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

r every use of it.

afte

Whe

n 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.

CHAPTER 1: GENERAL DESCRIPTION

[1] Important service notes

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard) Before returning the audio product to the use r, 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 out-

let.

* Using two clip leads, connect a 1.5 kohm, 10 watt

resistor paralleled by a 0.15 µF 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.

CD-G15000/CP-G15000S

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.
