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
“TGA860RU_DEF_RevXXX_YYY.bat”. (*3).
11) Country version batch file: Execute the command
“TGA860RU_W_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).
