11.6. Things to Do after Replacing IC or X'tal
If repairing or replacing BBIC (FLASH type), EEPROM and X'tal, it is necessary to download the required data such as
Programming data or adjustment data, etc. in memory.
The set doesn't operate if it is not executed.

The set doesn't operate if it is not executed.
11.6.1. How to download the data
11.6.1.1. Base Unit
First, operate the PC setting according to The Setting Method of JIG (Base Unit)(P.45).
Then download the appropriate data according to the following procedures.
Then download the appropriate data according to the following procedures.
Note:
(*1) XX: country code, YY: revision number, ZZ: Voice Prompt
“XX”, “YY” and “ZZ” vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The Setting
Method of JIG (Base Unit) (P.45).
(*2) Refer to Check Point (Base Unit) (P.35)
“XX”, “YY” and “ZZ” vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The Setting
