[{{ :licensing:license_information.zoom65.png?nolink |//Maintenance Window - License State page//}}] Usually, the core will be delivered without a firmware license. This firmware license will be sent via e-mail (see [[licensing:firmware|Receiving the Firmware License]]). Until a valid license is entered, the ''Remaining Operation Hours'' will be shown here. After 800 hours operation time without a valid license, ''invalid'' will be shown. If a valid firmware license is entered to the core, unlimited valid will be displayed. **Note**\\ Until a valid license is entered, the console can be used without restrictions for 800 operating hours. When the core is used for 600 operating hours, ''License invalid'' will be shown in the TFT and module displays. \\ After a total of 800 hours of operation without a valid firmware license, the system will be interrupted by a random reset approximately once per hour. When a license for a PC software or a feature upgrade is available in the device, the product number, the product name and the number of available licenses will be shown in that window.
