Thank you very much for your invaluable feedback!
When the Sphere2 detects a connection with specific AVer visualizers, the Class feature will be automatically enabled. Or you will be requested to enter an activation key to enable the Class function. Please note that you will need to purchase an activation key per PC/Mac if the AVer visualizer you are currently using is not compatible with free access to the Class feature. To acquire the activation keys or report any problems you experienced activating the class function please directly contact your local resellers.
