Help with Rainsoft water softener. Manual?

So I see a few other posts on here about this.. I just bought a new house and It has a "Rain Soft" model AQ24T water softener installed in it, its an older model (early 90's) and I dont have any instruction Manual. Suposably a company came in and programed it for me when I bought the place but it never regenerated and flushed salt water through the tank.. Then I got messing with it after the alarm was going off on it, and I reset everything, I still dont have it all set up right tho, alarm keeps going off randomly and I dont think its regenerating still unless I cycle it by pressing the button. I dont know how to set some of the settings on it. If anyone has a PDF file of the manual for one of these I would appriciate any help.. or if anyone knows more about programing one that would be great too. Thanks.
