Which page allows the user to activate purchased algorithms?

The page that allows the user to activate purchased algorithms is found in the Frame > System > License section. This page is specifically designed for license management and enables users to handle their purchased algorithms efficiently. Upon navigating to this part of the system, users can view the status of their licenses, activate new algorithms, and manage existing ones. This functionality is fundamental in ensuring that users can utilize the full capabilities of the System 6000 after purchasing additional software features or algorithms.

The other options do not directly pertain to the activation of algorithms. The Main > Card selection is typically associated with handling presets and physical inputs or outputs rather than licensing. The Frame > System > Main primarily serves as an overview page showing system information and settings, lacking the specific functionality for licensing. Lastly, the E1, E2, E3, E4 menus are designated for processing and effect control rather than accessing licensing details. Each of these choices serves different operational aspects of the System 6000, but only the License page provides the necessary functions for activating purchased algorithms.
