SYSTEM SETTINGS
Setting mode when an administrator is logged in
An administrator can configure settings that are more advanced than the settings available to a guest or user.
When user authentication is enabled, settings may be allowed without entering the administrator password based on the
rights of the logged in user. For the state of the settings, ask the administrator of the machine.
