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)

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.

NOTE  THE  IC301,  IC302,  IC303,  IC404,  IC405,  IC501,  
IC503,  IC505,  IC506,  IC507,  IC508,  IC509,  IC601,  IC602,  
IC701,  IC751,  IC752,  IC802,  IC803,  IC901  AND IC903  
ON  THE  MAIN  BOARD  REPLACING
When IC301, IC302, IC303, IC404, IC405, IC501, IC503, IC505, 
IC506, IC507, IC508, IC509, IC601, IC602, IC701, IC751, IC752, 
IC802, IC803, IC901 and IC903 on the MAIN board is damaged, 
exchange the new MAIN board for the MAIN board which IC 
damaged.

NOTE  THE  CN881  ON  THE  MAIN  BOARD  REPLAC-
ING
When CN881 on the MAIN board is damaged, exchange the new 
MAIN board for the MAIN board which connector damaged.

NOTE  THE  C104  AND  C204  ON  THE  MAIN  BOARD  
REPLACING
When C104 and C204 on the MAIN board is damaged, exchange 
the new MAIN board for the MAIN board which capacitor dam-
aged.

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.

Flexible Circuit Board Repairing
•   Keep the temperature of soldering iron around 270 °C during 

repairing.

•   Do not touch the soldering iron on the same conductor of the 

circuit board (within 3 times).

•   Be careful not to apply force on the conductor when soldering 

or unsoldering.
