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.

First, operate the PC setting according to The Setting Method of JIG(P.48).
Then download the appropriate data according to the following procedures.

(*1) WW: 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 The Setting
Method of JIG (P.48).

Items

How to download/Required adjustment

EEPROM (IC611)

Adjusted parameter data is stored in memory.
(country version batch file, default batch file,
etc.)

1) Change the address “0001” of EEPROM to “55” to download
the data.
2) Default batch file: Execute the command “default.bat”.
3) Country version batch file: Execute the command 
“TGC31EU_WW_RevXXX_YYY.bat” (KX-TGC310) or 
“TGC32EU_WW_RevXXX_YYY.bat” (KX-TGC320)(*1)
4) Clock adjustment

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
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 ± 15 Hz.

First, operate the PC setting according to The Setting Method of JIG (P.48).
Then download the appropriate data according to the following procedures.

(*2)  WW: country code, XXX_YYY: revision number

How to download/Required adjustment

FLASH(IC4)

Programming data is
stored in memory.

1) Make sure to connect the JIG cable, then disconnect the DC Power in order to 
download the data.
2) Execute the command “flw441 *********.hex”.
3) Connect the DC Power.
4) Press and hold the handset Power key.
5) While holding down the handset Power key, press the PC Enter key once.
6) After a few minutes, “Successful upgrade” is displayed on the PC indicating 
downloading has finished.
7) Detach the JIG cable, then press the handset Power key to turn it on.
8) Connect the JIG cable again, and execute the command "getchk”, then confirm 
the checksum value is correct.

• If the downloading fails, start again from step 1).

9) Default batch file: Execute the command “default.bat”.
10) Default batch file (remaining): Execute the command 
“TGCA30EURU_DEF_RevXXX_YYY.bat”. (*2)
11) Country version batch file: Execute the command 
“TGCA30EURU_WW_RevXXX_YYY.bat”.(*2)
12) Clock adjustment: Refer to Check Point (H). (*4).
13) 1.8 V setting and battery low detection: Refer to Check Point (A), (F) and (G). 
(*4).

EEPROM (IC7)

Adjusted parameter data is
stored in memory.
(country version batch file,
default batch file, etc.)

1) Default batch file: Execute the command “default.bat”.
2) Default batch file (remaining): Execute the command 
“TGCA30EURU_DEF_RevXXX_YYY.bat”. (*2)
3) Country version batch file: Execute the command 
“TGCA30EURU_WW_RevXXX_YYY.bat”.(*2)
4) Clock adjustment
5) 2.35 V setting and battery low detection

Battery Monitor Check

-

1) Apply 2.25 V between BATT+ and BATT-.
2) Execute the command
    sendchar PAD
    sendchar LED 0    
    sendchar CRX 0 1    
    sendchar AD1    
    It assumes that the return value is XX.
    a) 6c   XX   71: No need to adjust
    b) XX: 6A ~ 6B: Need to adjust
    XX: 72 ~ 74: Need to adjust
    Write AD value of 2.25 V to EEPROM.
    ex) read data: XX = 6A, write data:YY = 6A
    read data: XX =73, write data: YY = 73  
    EEPROM = 0009 (Low Voltage) write “YY“
    Execute the command “wreeprom 00 09 01 YY“.
    EEPROM  = 000A (No Voltage) write “YY - 1D“
    Execute the command “xwreeprom 00 0A 01 ZZ“.
    Note:
    No Voltage writing data limit is “00“.
    c) XX: 00 ~ 69: Reject
    XX: 75 ~ FF: Reject    

Battery Low Confirmation

-

1) Apply 2.40 V between BATT+ and BATT-.
2) Confirm that there is no flashing of Battery lcon.
3) Apply 2.25 V ± 0.08 V between BATT+ and BATT-.
4) Confirm that there is flashing of Battery lcon.

Battery Clock Adjustment 
(X1)

CLK

1) Apply 2.6 V between BATT+ and BATT- with DC power.
2) Input Command “sendchar sfr“, then you can confirm the current value.
3) Check X’tal Frequency. (10.368 MHz ± 100 Hz).
4) If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CLK
execute in the command “sendchar sfr xx xx (where xx is the value)“ so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
