Problem/Question Possible Cause / Remedy
Shorten the distance between the watch and the
chest strap.
Adjust the position of the chest strap and the
elastic tension strap. Make sure the chest strap
sensors are wet.
Check the battery in the chest strap and replace it
if necessary.
Move away from other heart rate monitors or
other sources of electrical or radio interference.
Tighten the elastic tension strap. If the chest strap
is too loose, the movement of the contact points
disturbs the detection of the heart rate signal.
Hairy chest may also weaken the contact. Try to
find the best possible position for the contact
points. No heart rate
signal
Dirty contact points. Clean the chest strap.
