Hey guys, Firstly... great forum... Anyway to the point. I bought a Huffy brand speedometer from K-mart a few years ago and have lost the instructions. Just recently, I replaced the batteries and all the settings were cleared, I'm not sure how to tell it what bike I have. On start up it gives me a 4 digit code: ABCD Where the numbers I can put in is: A: 1-4 B: 0-9 C: 0-9 D: 0-9 From memory, I'm suppose to enter my wheel size or something to tell it what bike configuration i have. I'm guessing that since I have a 26" MTB so 26 is part of that code... I can't think of anything else that I need to put it?? If anyone has a Huffy brand speedo, can you sheed some light this please? TIA!
