An LED lights up to indicate that the remote control is functional.
This light will turn off after XX seconds to indicate stand by setting the remote control (battery saving).
A few first pressure is the key to awaken the télécommande.Il must then press the desired key
to perform the desired action.
The precision of the mouse a little tight, but we get to use it.
For use on PC, in my case linux mint 17.0, no cares about recognition.
