28 MZ-N10 Rewriting the P atch Data at Replacement of Main Board T his set requires the patch data in the non volatile memory (IC851) to be re written 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-N10 5. Confirm tha t 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-N10 • Confirmation of contents of the patch data re writed 1. Clic k the [READ] button to conf irm the contents of the patch data rewrited. 2. T he application reads out the front and re verse patch areas and displays the results in the edit box.
31 MZ-N10 • Removing the set Remove the set as follo wing procedure after re writing the patch data and confirmation. Note : When the following procedure is not completed b ut USB cable is extracted, the application does not recognize the set at e xchanging the set.
32 MZ-N10 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 v alues using the application not suitable for the microcomputer v ersion could cause the set to malfunction.
33 MZ-N10 5. Confirm tha t 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-N10 7. T he operation will terminate with “Compere OK” gi ven to all areas. If “Compere NG” is giv en to any area, the non volatile memory will be faulty .
35 MZ-N10 9. Confirm that the windo w becomes as sho wn below where the [Write + V erify] button is inacti ve. 10. Disconnect the USB cable from the personal computer and the USB cradle.
