Anyone have a owner's manual or know what each button does?

I just acquired a 20 year old bosch dishwasher [E-NR: SMU7056US/09] that is fully functional. No manuals are available any longer for it. ALL I NEED TO KNOW is what each button does. There are seven rectangular buttons lined up in a row on the top right side of the door. The far left one is (1) Power On/Off. The six to the right starting at the left should be (2) power scrub, (3) Auto, (4) Regular/Normal, (5) ?, (6) ?, (7) ?. Any clue what the last should be? Have you ever seen one of these before? Have you previously owned one of these or have access to an old manual?

A preemptive thanks one way or the other for your reply,
