Lektra TM8M21 Electronic Decade Interval Timer Good Used Working Condition.

Here's a nice vintage photographic timer to use with those big enlargers. Everything works as it should. I couldn't figure out how to use the two ungrounded AC outlets imprinted "START" and "DODGE". Anybody out there have a clue?
