Is there somewhere that shows the blink codes. I just bought this thing Saturday (four days ago) and it is blinking 10 times now. Does it blink if the cartomizer is empty. i searched here and found one post that said he had a 10 blink but i didn't see any responses. recharged it last night but this is still my first carto (is that right?) so it could be empty. i was getting good vapor till it just stopped having any.
