12.5. Things to Do after Replacing IC or X'tal

If repairing or replacing 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.

12.5.1. How to download the data

12.5.1.1. Base Unit
First, operate the PC setting according to The Setting Method of JIG (P.52).
Then download the appropriate data according to the following procedures.
BBIC(IC501)
EEPROM (IC611)
X'tal (X1)
Note:
(*1) WW: model number, XXX_YYY: revision number, ZZZ:Voice prompt, AA: Baud rate(9600/19200/57600/115200)
"XXX_YYY" and "ZZZ" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The
Setting Method of JIG (P.52).
When adjust the frequency the BT Unit.

Programming data is stored in memory.
Adjusted parameter data is stored in memory.

1) System Clock adjustment.
1) Change the address "0001" of EEPROM to "AA" to download
the data.
2) Default batch file: Execute the command "default.bat".
3) Country version batch file: Execute the command
"TGH260_US_US_RevXXX_YYY.bat". (*1)
4) System Clock adjustment
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
current value.
3) Check X'tal Frequency.(10.368MHz ± 41Hz).
4) If the frequency is not 10.368MHz ±41Hz, adjust the
frequency of CLK executing the command "sendchar sfr xx xx
(where xx is the value)" so that the reading of the frequency
counter is 10.368MHz ±5Hz.

Description
Wait 10seconds and connect JIG
Enter"XBT 1" and then "OK" is back
when it succeeds to enter test mode.
Confirm a default value before adjusting the
frequency.
Adjust the frequency to "2441MHz ± 10kHz" by
changing the value of,
