As far as i know, the first one's made do not have a magnet at the bottom end to turn the coller on. If you own a mk3 box, look at the bottom end and see if it has an arrow marked on the case, if it has, then it should be a newer type box and it should turn on the new collers.
ps, if it came with normal click shut collers, that dont mean the box wont turn on the new collers, it's that arrow you got to look for. I got old click shut collers in the wrapper with the newer box.
