NOTES  ON  CHIP  COMPONENT  REPLACEMENT
• 
Never reuse a disconnected chip component.
• 
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY-RELATED  COMPONET  WARNING!
COMPONENTS  IDENTIFIED  BY  MARK  
0  OR  DOTTED  LINE  
WITH  MARK  
0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN  
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS 
 
WHOSE  PART  NUMBERS  APPEAR  AS  SHOWN  IN  THIS  
MANUAL  OR  IN  SUPPLEMENTS  PUBLISHED  BY  SONY.
UNLEADED  SOLDER
Boards requiring use of unleaded solder are printed with the 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
Unleaded solder has the following characteristics.
•  Unleaded solder melts at a temperature about 40 °C higher 
than ordinary solder.
 
Ordinary soldering irons can be used but the iron tip has to be 
applied to the solder joint for a slightly longer time.
 
Soldering irons using a temperature regulator should be set to 
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if 
the heated tip is applied for too long, so be careful!
• Strong 
viscosity
 
Unleaded solder is more viscous (sticky, less prone to fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.
• 
Usable with ordinary solder
 
It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.
Notes on the AC power adaptor
• 
When operating the unit with the internal batteries, remove the 
AC power adaptor from the wall outlet and the DC IN 9 V jack. 
Make sure that the plug of the external power source is discon-
nected before operating the unit.
•  Use the supplied Sony AC power adaptor only. The polarity 
of the plugs of other manufacturers may be different. Failure 
to use the supplied AC power adaptor may cause the unit to 
malfunction.
