Multicam SF series keypad information

I am in the process of bringing a SF series back on line after having it sit for over 5 years. In that time I have forgotten how to do some things with the keypad. It is the pedestal type, not the pendant.style.
Does someone have a manual or quick start guide on the keypad button functions.

Also, are the keypads repairable. Some of the keys are intermittent and some bring up commands that I have never seen before.

We purchased the machine used about 20 years ago and it came with no manual. We had a Multicam tech come check it out when we installed it and he gave us a 10 min lesson and that was it.
I used to run it daily, but I guess either I've gotten old, or my memory is full.
