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.

• In the interests of user-safety (Required by safety regulations in

some countries) the set should be restored to its original condition
and only parts identical to those specified be used.

Example:

Indicates lead-free solder of tin, silver and copper.

When 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.

Lead-free wire solder for servicing

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 soldring 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. 

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 wet ability, 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 off or 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.

"MAIN, DISPLAY, iPod, EXCHANGE, SMPS, ANALOGUE, KEY, TUNER, SWITCH, AIRPLAY 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.
