I just got a new specialized double wireless computer and cannot get it to pair with any sensors other than my heart rate monitor. Cadence and speed do not connect and I get a fail message when I go through the pairing drill. I have replaced batteries in both units and reset the main unit. I have the sensors installed as per the manual. even if I was not getting reading because of where the magnets are placed it seems I should still be linking up with the sending units. I did purchase at the LBS but hoped someone has a solution before I have to take the unit back in.
