28 MZ-NF810/NF810CK Rewriting the P atch Data at Replacement of Main Boar d (IC851) This set requires the patch data in the nonvolatile memory (IC851) 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.
29 MZ-NF810/NF810CK 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 window .
30 MZ-NF810/NF810CK • 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.
31 MZ-NF810/NF810CK • 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 recognize the set a t excha nging of the set.
32 MZ-NF810/NF810CK Rewriting the NV v alues Caution: T he application that meets the microcomputer version in this set must be used w hen rewriting the NV values. Re writing the NV values using the application not suitable for the microcomputer version could cause the set to malfunction.
33 MZ-NF810/NF810CK 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 window .
34 MZ-NF810/NF810CK 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 faulty .
35 MZ-NF810/NF810CK 9. Confirm that the windo w becomes as shown belo w where the [Write + V erify] button is inacti ve. 10. Disconnect the USB cable from the personal computer and the set.
