As deciphering the picture may take a long time, I have created a rule of quick solving the scheme:
I remember only 2 (any) signs (for instance beer and boot)
I place them right on the button machine, and then just guess the other three (if you don't like guessing so much, all you need is to remember 3 instead of 2... you can surely easy correctly place the remaining two in right order, at least on second try
)
