13.7. 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 Program-
ming data or adjustment data, etc in memory.
The set doesn't operate if it is not executed.

First, operate the PC setting according to The Setting Method of JIG (Base Unit)(P.50).
Then download the appropriate data according to the following procedures.

1) Change the address “0001” of EEPROM to “55” to download
the data.
2) Default batch file: Execute the command “default.bat”.

X'tal (X501)
System clock
Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Apply 5.5V between DCP ad DCM with DC power.
2) Input Command "sendchar sfr", then you can confirm the cur-
rent value.
3) Check X'tal Frequency.(13.824 MHz ± 100 Hz).
4) If the frequency is not 13.824 MHz ± 100 Hz, adjust the fre-
quency of CKM executing the command "sendchar sfr xx xx
(where xx is the value)" so that the reding of the frequency
counter is 13.824000 MHz ± 7 Hz.
