Got new IC-DK03 keyboard. Nice layout, but unable to get Mac activated. 

Am using 2.4G USB receiver. Keyboard works fine. 

There is no obvious indicator that functionality for Mac OS is operational. 

When I test Mac OS commands they are not functional. 

Al my systems are Apple and I really need to get this working. 

Is Mac OS setup a once off and remembered by the keyboard or every time you switch it on. 

User guide says to ensure you read choose the right system. Perhaps a switch would be much simpler...
