Bought this 1994 Tige SLM Comp Used. Perfect pass 6.3 Single line display was not working (bad buttons) scored a new single line display and the OG PP working Great. Trying to figure out what these buttons supposed to do. They are not plugged into anything either? What is this "Slalom Times" Pad array?

I have no clue what that thing is in the first picture.
The timer was for the course you would put in the speed you were running then had to hit a start button when the boat hit the entry gates, from that point the device would sound a tone at every boat gate and a different tone at the end gate. It would give you an idea if you were close to the actual desired speed.
