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.

First, operate the PC setting according to The Setting Method of JIG (Base Unit)(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 (Base Unit) (P.48).
(*2) Refer to Check Point (Base Unit) (P.37)

Items

How to download/Required adjustment

EEPROM (IC502)

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

1) Change the address “0001” of EEPROM to “DD” to download 
the data.
2) Default batch file: Execute the command “default.bat”.
3) Country version batch file: Execute the command 
“PRW110RU_WW_RevXXX.bat” (KX-PRW110RU) or 
“PRW120RU_WW_RevXXX.bat” (KX-PRW120RU) (*1)
4) Clock adjustment: Refer to Check Point (E). (*2)

X'tal (X1)

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.(10.368 MHz ± 100 Hz).
4) If the frequency is not 10.368 MHz ± 100 Hz, adjust the 
frequency of CKM executing the command "sendchar sfr xx xx
(where xx is the value)" so that the reding of the frequency
counter is 10.368 MHz ± 5 Hz.

First, operate the PC setting according to The Setting Method of JIG (Handset)(P.51).
Then download the appropriate data according to the following procedures.

(*3) 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 (Handset) (P.51).

(*4) Refer to Check Point (Handset) (P.39)

How to download/Required adjustment

FLASH(IC2)

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
“PRWA10RU_DEF_RevXXX_YYY.bat”. (*3).
11) Country version batch file: Execute the command
“PRWA10RU_WW_RevXXX_YYY.bat”. (*3).
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 (IC3)

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) Default batch file (remaining): Execute the command 
“PRWA10RU_DEF_RevXXX_YYY.bat”. (*3)
4) Country version batch file: Execute the command 
“PRWA10RU_WW_RevXXX_YYY.bat”. (*3)
5) Clock adjustment: Refer to Check Point (H). (*4)
6) 1.8 V setting and battery low detection: Refer to Check Point 
(A), (F) and (G). (*4)

X'tal (X1)

System clock

Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Refer to Check Point (C). (*4)
