This operation is called "invalidating transfer of a license".Since it is possible to select the same device as a destination of the transfer, this servicemode can be also used to invalidate a function on a temporary basis. Careful attention,however, is required because, if you invalidate a function by mistake, you need to contact asales company for recovery.Take utmost precaution when inactivating the licenseWhen invalidating transfer of a license, it is necessary to invalidate the license by entering theservice mode and issue a function invalidation certificate key, which certifies that the licensehas been invalidated. This operation can be executed for each optional function. At the pointwhen a function invalidation certificate key is issued, the function is invalidated and becomesunavailable. When you report this function invalidation certificate key, the serial number ofthe transfer origination device, the serial number of the transfer destination device, and thereason why you need to perform the transfer to a sales company, a new license key is issuedfor installation for the transfer destination device. Be sure to write down the new license keywhen you receive it and, when it is registered in the transfer destination device successfully,inform the user of the new license key and explain him/her to keep it at hand.Operation Procedure(1) Enter the service mode and display the following service mode.
