The program is installed to \Program Files\btIO\btIO.exe and a shortcut in the autostart folder is created.

There are three icons:
- Green BT-Icon = Bluetooth is enabled and in discoverable mode.
- White BT-Icon = Bluetooth is enabled and in connectable (invisible) mode.
- Red BT-Icon = Bluetooth is disabled.

You can switch between connectable and disabled by simply pressing the icon in the tray bar.
When you tap'n'hold the icon a menu apears that lets you set the mode you like, and lets you exit the program.
