Things to Do after Replacing IC or X'talIf repairing or replacing BBIC (FLASH type), EEPROM and X'tal, it is necessary to download the required data such as Program-ming data or adjustment data, etc in memory.The set doesn't operate if it is not executed.11.7.1. How to download the data11.7.1.1. Base UnitFirst, operate the PC setting according to The Setting Method of JIG (Base Unit) (P.61).Then download the appropriate data according to the following procedures.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, PNZZ- mentioned in The SettingMethod of JIG (Base Unit) (P.61).(*2) Refer to Check Point (Base Unit) (P.48)Items How to download/Required adjustmentBBIC (FLASH type)(IC7)Programming data is stored in memory. 1) Make sure to connect the JIG cable, then disconnect the DCPower in order to download the data.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 thePC 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“TG8421XXrevYY.bat”.
