Here is a picture of the keyboard
I have had this device for a long without using it but now it would be very useful. The only problem I am having is that I can’t make the Function keys work. For example, pressing F12 will increase volume. But no combination of pressing Fn with F12 will make it ever send F12. Instead it just always works as increase volume button.
The manual doesn’t give any hints.
Does anybody know how to make this work?
