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.
n
For the replacement of the ADA-55 board, please buy BKPF-L753A because ADA-55 mounted circuit board is not prepared for spare parts.

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 recom­mended 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.
