58KX-TG234SK/KX-TGA470B12.6. Things to Do after Replacing IC or X'talIf repairing or replacing EEPROM and X'tal, it is necessary to download the required data such as Programming data or adjustmentdata, etc in memory.The set doesn't operate if it is not executed.12.6.1. How to download the data12.6.1.1. Base UnitFirst, operate the PC setting according to The Setting Method of JIG (P.51).Then download the appropriate data according to the following procedures.Note:(*1) XXX_YYY: revision number“XXX”, “YYY” vary depending on the country version.
