11.6 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.
11.6.1 How to download the data
11.6.1.1 Base Unit
First, operate the PC setting according to
Then download the appropriate data according to the following procedures.
EEPROM (IC611)
Adjusted parameter data is stored in
memory.
(country version batch file, default batch file,
etc.)
X'tal (X501)
System clock
Note:
(*1) W: country code, XXX_YYY: revision number
"XXX_YYY:" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in
Method of JIG]

How to download/Required adjustment
1) Change the address "0001" of EEPROM to "55" (KX-TGC450) or "AA"
(KX-TGC460) to download the data.
2) Default batch file: Execute the command "default.bat".
3) Country version batch file: Execute the command
"TGC41x_EU_W__RevXXX_YYY..bat" (KX-TGC450) or
"TGC42x_EUEX_W_RevXXX_YYY.bat" (KX-TGC460) (*1)
4) 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.(13.824 MHz ± 100 Hz).
4) If the frequency is not 13.824 MHz ± 100 Hz, 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 13.824000 MHz ± 5 Hz.
