The heart rate display is not correct, why?

  • Perhaps the sensor contact surfaces of the chest strap are not moistened
  • Check the chest strap for firmer positioning around the chest
  • Also check the battery
  • It is not advisable to simultaneously use the heart rate monitor and a radio bicycle computer, as the signals from the bicycle computer transmitter can cause functional errors with the heart rate monitor
  • Signals from other chest straps in the vicinity of less than 2metres / 6foot 6 inch may cause incorrect values


Hi - checked all the troubleshooting but that hasn't helped as none of the reasons the HR display might not be correct apply. It's far too high. I've just bought it and am setting it up using the CSX video's on utube. I've put in female, 59kg, DOB: Dec '63 and the MHR it calculated is 169. Now I have coupled the watch and belt strap the HR display is showing over 100% (200) and keeps beeping and flashing red - I've not even done any exercise yet! It's still going mad even after I've taken the belt off and reset the HR to re-couple? Please could you advise?
