Distortion and interference
In the HR monitor, a receivor for signals from the chest strap
transmitter is integrated. During use, it may arise that the HR
monitor receives signals other than those transmitted by the chest
strap.
How can I recognize interference?
Interference can be recognized in that the values displayed are
unrealistic. If your normal heart rate amounts to 130 bpm and it is
suddenly shown to be 200, then a short-term disturbance is present.
Once you have removed yourself from the vicinity of the source
causing the disturbance, the values will automatically resume being
accurate. Please note that distorted values can mildly influence the
training result displays and overall values.
What kind of causes for interference are there?
In some situations, short-range electromagnetic interference can
occur. In order to avoid these, keep well away from these sources.
