Activation Key Code and Key Management System To obtain additional activation keys, you need to purchase the appropriate activation key codes and access the Key Management System. You can download the activation keys as an activation key file from the Key Management System. To download the activation keys, enter the MPR ID number shown on the IPCMPR card in the PBX, and activation key number and registration ID provided on each activation key code. For information about the type of activation key codes available, refer to "Additional Activation Keys in the SD Memory Card (Activation Key Files)". Note • You can only download the activation key file once using the activation key number and registration ID provided on the activation key code. • Up to 8 activation keys can be downloaded as one activation key file. • Up to 100 activation key files can be installed on the SD Memory Card. • It is possible to send the activation key file to a specified e-mail address at the same time as downloading it to a PC. • Make sure to backup the downloaded activation key files on your PC. • In the event of a system malfunction, you need a temporary activation key for maintenance purposes. The temporary activation key can only be used for a limited time period, and can be downloaded from the Key Management System in the same way as downloading activation key files.
