The heart rate monitor display has frozen / no longer responding?

Reset the heart rate monitor if the display is “frozen” or irregular symbols appear:
  • To Reset - Press and hold the SEL and SET button simultaneously for approx. 3 seconds. All display segments will briefly appear and you will reach the default settings again
  • Alternatively: Remove the battery and insert it. This will reset the microprocessor
  • Please pay attention to the small spring protruding from the movement. Handle it carefully so that this spring is not lost.
After this the heart rate monitor should function normally again.
