I just got a Kearsarge 502 Timer, but it came without a manual. Does anyone happen to have a copy???

I would like to be able to use this on a Beseler CB7 with colorhead. I currently have a Kearsarge 300 series timer on the enlarger, and it works just fine with the power cables daisy-chained so that from the colorhead transformer it goes into the timer, and from there to the fan/blower.

With the 502 timer, I don't even know which plug receptacle in the back to use, not to mention what all these buttons do!

Thank you.
