I don't believe my Compur is marked with anything saying #1, and so then can I assume that 'I+1' means 1? What does the "I" stand for? It's this nomenclature that's throwing me off...

The fact that I'm getting trouble from my Compur makes me wonder... I'll call the repair-tech but perhaps it just needs to be exercised and it will loosen up (though I don't have a good feeling about that).

thnx Dan
