1. Safety Related Components Warning  
w
w
An IC link is critical parts to safe operation.  
Replace this component with Sony parts whose part  
numbers appear in this manual published by Sony.  
If not, this may cause a fire or electric shock.  
Be sure to use the specified component in this manual.  
Components marked ! are critical to safe operation.  
Therefore, specified parts should be used in the case of  
replacement.  
2. Standardization of Parts  
Some repair parts supplied by Sony differ from those  
used for the unit. These are because of parts common-  
ality and improvement.  
The IC link is mounted on the ADA-55 board. Be sure to  
replace with the specified IC link as shown below after  
removing the foreign substances that may cause the shorts.  
Parts list has the present standardized repair parts.

1-5. Unleaded Solder  
1-5. Unleaded Solder  
Boards requiring use of unleaded solder are printed with a  
lead free mark (LF) indicating the solder contains no lead.  
(Caution: Some printed circuit boards may not come  
printed with the lead free mark due to their particular size.)  
: LEAD FREE MARK  
m
. Be sure to use the unleaded solder for the printed circuit  
board printed with the lead free mark.  
. The unleaded solder melts at a temperature about 40 dC  
higher than the ordinary solder, therefore, it is recom-  
mended to use the soldering iron having a temperature  
regulator.  
. The ordinary soldering iron can be used but the iron tip  
has to be applied to the solder joint for a slightly longer  
time. The printed pattern (copper foil) may peel away if  
the heated tip is applied for too long, so be careful.
