Space: Power. Up/Down: Frequency. Left/Right: Amplitude.
I was working on this a while ago, but I stopped working on this for a while and forgot what I was doing with it. If you set the amplitude (3-digit number) and the frequency (the up/down thingy) to the correct settings while the power is on, the things at the top start doing something. I might add on to this in the future, but it's unlikely.
