Does anyone have an instruction manual for the original dytter audible skydiving altimeter?

Hello! I have a question for those of you who has been part of the skydiving community for a very long time. I got really into skydiving while in college a few decades ago, and i bought the equipment I needed, to include the original Dytter audible altimeter. I liked having it and felt like it added significantly to my altitude awareness when flying camera or doing RW. My stepson has recently gotten into skydiving quite heavily and I want to lend the Dytter to him, so he can have the same increase in altitude awareness on his jumps. Built into the case it has a two step calibration procedure (1. Turn the dial slowly either direction until it sounds. 2. Turn slowly clockwise to set the altitude warning, with each dot indicating 1000 feet.). I don't recall if it came with any type of instruction manual or not, that may have included additional information. If it did I would like to get a copy to give to him. This is probably a long shot, but does anyone have a copy?

You already know all you need. That's all the knowledge there is.
