Open FirmaCerta software with the signature device inserted to the computer, then click on "Device Manager > Certificates Renewal".
Read and confirm the acceptance of vexatious clauses, then click on the NEXT button.
Click on "Select Device" and enter the Pin for the recognition of the latter and the reading of the certificates.
The tool will propose to display (optional) and digitally sign (mandatory) a .pdf file for the request of the certificates renewal. Select "OK", when required, to complete the signature operation.
Wait until the renewal procedure will be completed.
At this point, the tool will propose to sign the renewal certificates contract automatically, asking the user if he/she wants to view it or not.
After the certificates will be displayed, select "Renew Certificates".
Then, the tool will ask the user if he/she wants to view the request for renewal or not; in both cases, the file will be digitally signed.
If you have selected to view the PDF document, the program will display the certificate renewal contract. To complete the whole process the user will have to apply his/her digital signature by clicking on the file shown.
Wait until the renewal process is completed and finally click on OK.
