- Page 31 MZ-N520/N520CK Rewriting the Patch Data at Replacement of Main Board This set requires the patch data in the nonvolatile memory (IC852) to be rewritten using the application, when the MAIN board was replaced. Caution: The application that meets the microcomputer version in this set must be used when rewriting the patch data. Rewriting the patch data using the application not suitable for the microcomputer version could cause the set to malfunction.
- Page 32 MZ-N520/N520CK 5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the Device Name block and the Version block in the window. 6. Click the [Write + Read] button. The patch data writing and the verify processing will be executed automatically in the following order:...
- Page 33 MZ-N520/N520CK • 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.
- Page 34 MZ-N520/N520CK • Disconnecting the USB cable Disconnect the USB cable as the following procedure after rewriting the patch data and confirmation. Note : When the following procedure is not completed but USB cable is extracted, the application does not recognize the set at exchanging of the set.
- Page 35 MZ-N520/N520CK Rewriting the NV values Caution: The application that meets the microcomputer version in this set must be used when rewriting the NV values. Rewriting the NV values using the application not suitable for the microcomputer version could cause the set to malfunction.
- Page 36 MZ-N520/N520CK 5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the Device Name block and the Version block in the window. 6. Click the [Write + Verify] button. The NV values writing and the verify processing will be executed automatically in the following order:...
- Page 37 MZ-N520/N520CK 7. The operation will terminate with “Compere OK” given to all areas. If “Compere NG” is given to any area, the nonvolatile memory will be faulty. 8. Click the [USB DISCONNECT] button.
- Page 38 MZ-N520/N520CK 9. Confirm that the window becomes as shown below where the [Write + Verify] button is inactive. 10. Disconnect the USB cable from the personal computer and the set.
