1-2. IC Link Replacement
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.
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.

1-3. Shield Case
(S/N10001 through S/N17325)
The shield case is a component to shield the DD-36 board.
Before checking the DD-36 board, unsolder and remove
this shield case.
1-1. Notes on Repair Parts
1. Safety Related Components Warning
w
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.
Parts list has the present standardized repair parts.
3. Stock of Parts
Parts marked with “o” at SP (Supply code) column of
the spare parts list may not be stocked. Therefore, the
delivery date will be delayed.

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.
