31 MZ-NF610 Rewriting the P atch Data at Replacement of Main Boar d This set requires the patch data in the nonvolatile memory (IC852) to be rewritten using the application, when the MAIN board was replaced. Caution: T he application that meets the microcomputer version in this set must be used when re writing the patch data.
32 MZ-NF610 5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the Device Name block and the Ve r sion block in the windo w .
33 MZ-NF610 • Confirmation of contents of the patch data rewrited 1. Click the [READ] button to confirm the contents of the patch data rewrited. 2. The application reads out the front and reverse patch areas and displays the results in the edit box.
34 MZ-NF610 • Disconnecting the USB cable Disconnect the USB cable as the following procedure after rewriting the patch data and confirmation. Note : W hen the follo wing procedure is not completed but USB cable is extracted, the application does not reco gnize the set at exchan ging of the set.
35 MZ-NF610 Rewriting the NV v alues Caution: T he application that meets the microcomputer version in this set must be used when re writing the NV v alues. Rewriting the NV values using the application not suitable for the microcomputer version could cause the set to malfunction.
36 MZ-NF610 5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the Device Name block and the Ve r sion block in the windo w .
37 MZ-NF610 7. The operation will terminate with “Compere OK” given to all areas. If “Compere NG” is giv en to any area, the non volatile memory will be f aulty .
38 MZ-NF610 9. Confirm that the windo w becomes as shown belo w where the [Write + V erify] button is inactiv e. 10. Disconnect the USB cable from the personal computer and the set.
