- Remove the remaining lead free solder on the PCB cleanly for soldering
of the new IC.
- Since the melting point of the lead free solder is higher than that of the
normal lead solder, it takes the longer time to melt the lead free solder.
- Use the soldering iron (more than 70W) equipped with the temperature
control after setting the temperature at 350±30 degrees C (662±86°F).
Recommended Lead Free Solder (Service Parts Route.)
- The following 3 types of lead free solder are available through the
service parts route.
RFKZ03D01K-----------(0.3mm 100g Reel)
RFKZ06D01K-----------(0.6mm 100g Reel)
RFKZ10D01K-----------(1.0mm 100g Reel)

* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
2.4. How to replace the Lithium Battery
REPLACEMENT PROCEDURE
1. Remove the Top case, Front Panel, RAM/Digital P.C.B. Module, DV
Jack, Rear Panel, Front (L) P.C.B. and Main P.C.B. by referring the
Disassembling Procedure.
2. Unsolder the Lithium Batteries: B7501 and then replace it into new one.
( As shown in 13.2.4. The Main P.C.B. )
NOTE:
The lithium battery is a critical component. ( Type No.: CR2354-1GUFE Manufactured by Panasonic.)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity
contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
