11.6. Things to Do after Replacing IC or X'tal
Cautions:
Some of the content on this page may not apply to models from some countries.
11.6.1. Base Unit
Before making the following adjustment, ensure you have carried out PC Setting (P.63) in The Setting Method of JIG (Base
Unit)
.
Note:
(*1) XX: country code, YY: revision number, ZZ: Voice Prompt
“XX”, “YY” and “ZZ” vary depending on the country version. You can find them in the batch file, PQZZ- mentioned in JIG and PC
(P.63).
(*2) Refer to Check Point (Base Unit) (P.46)
Items
Necessary Adjustment
BBIC (FLASH type)
(IC7)
Programs for Voice processing, interface for RF
and EEPROM
1. Make sure to connect the JIG cable, then detach the DC
Power.
2. Execute the command “flw480 *********.hex”.
3. Connect the DC Power.
4. Press the PC Enter key once.
5. After a few minutes, “Successful upgrade” is displayed
on the PC indicating downloading has finished.
6. Detach the JIG cable, then disconnect the DC Power.
7. Connect the DC Power.
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. Country version batch file: Execute the command
“TG7320XXrevYY.bat”. (*1)
11. Clock adjustment: Refer to Check Point (G). (*2)
EEPROM (IC401)
Adjustment parameter data
(country version batch file, default batch file,
etc.)
1. Change the address “0000” of EEPROM to “55”.
2. Default batch file: Execute the command “default.bat”.
3. Country version batch file: Execute the command
“TG7320XXrevYY.bat”. (*1)
4. Clock adjustment: Refer to Check Point (F). (*2)
FLASH (IC421)
Voice prompt data
(vary depending on country version)
1. Wait more than 15 seconds after connecting the JIG
Cables.
2. Execute the command “TG732x832x_CBR57600_01”
3. Press the PC Enter key once.
4. Execute the command  "VPDL2008_01 -8M ZZ.bin" (*1)
(writing time: aprox. About 1 min (57600bps).)
