The Activation Key is used to associate a new VGo that has been powered on and connected to the network with the person who has purchased the VGo or who is assigned to administer the VGo.  When the VGo first connects to the network the activation code is display on the VGo screen.  The owner or administer then must enter that code into a field on a web page in VGoNet Manager.  This is described in detail in the user guide under “Add a VGo.”
