The screen you will see will either look like the image below or the columns will be horizontal:
When you start the outer two columns will be tilted, either both towards or away from the center column. Your task is to line them up so that they appear parallel to the center one. Thus you will either make the columns appear vertical or horizontal. The arrows pointing to the right rotate the outer columns to lean towards the center columns. The left arrows rotate the outer columns away from the central columns. The double arrows make larger steps in the same direction as the single arrows. When the three columns appear vertical or horizontal, click the button with the red ball.
