you need to blow sharply 3 times down the led end of the battery followed by 3 soft long blowings and a further 3 sharp blowings while repeating this mantra in your head "please make this work, please make this work"....just joking obiously, never heard of this and am surprised the function exists..would like to know what it re-sets exactly and how this works on any models where it does!
