Service caution for repair work using Lead Free Solder (PbF)
• The lead free solder has to be used when repairing the equipment for which the lead free solder is used.
(Definition: The letter of “PbF” is printed on the PCB using the lead free solder.)
• To put lead free solder, it should be well molten and mixed with the original lead free solder.
• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC.
• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the
lead free solder.
• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees
C (662±86
°
F).
Recommended Lead Free Solder (Service Parts Route.)
• The following 3 types of lead free solder are available through the service parts route.
RFKZ03D01K-----------(0.3mm 100g Reel)
RFKZ06D01K-----------(0.6mm 100g Reel)
RFKZ10D01K-----------(1.0mm 100g Reel)
Note
* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
2.2.1. Precautions for servicing

Note for assembly and disassembly
• When turning the unit over, be sure to close the dust cover or put a cardboard as a base, and place the unit on a soft thick cloth
or cushion, etc, to prevent cracking.
• When removing the DC motors and tone arm unit, be sure to attach a soft cloth inside the dust cover beforehand to prevent
cracking.

Note when moving the unit
Repackage the unit in the packaging it came in.
If you no longer have the packaging, do the following:
• Take off the turntable and turntable mat and carefully wrap them.
• Remove the head shell and balance weight from the tone arm and carefully wrap them.
• Clamp the tone arm with the arm clamp and tape it in place.
• Carefully wrap the main unit in a blanket or paper.
