To explain a brief illustrated instructions is pasted on the keyboard that explains in simple steps you have to do:
1) required number on the selector switch
2.) The press right button for Windows / iOS devices
3.) Confirm on the device and ready ....
The Playstations work with the Windows setting.
For mobile stories the keyboard is not suitable. Too heavy (weighs twice as much as my ipad MINI). But is not required for me so I pull from no star.
