Disable demo-mode (blinking pads) on padKontrol

[audiofail]

After not touching any pads or buttons for a few minutes, my Korg padKontrol goes into demo mode: the pads light up rythmically, making different figures.

I find this distracting when I'm working, but wouldn't like to switch off the entire device everytime time I don't use it for a couple of minutes.

Anyone knows a way to disable this somewhat annoying demo-mode?
