12.3 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.

12.4 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.
• Nearby power lines
• Walking through security gates in airports.
• Nearby overhead lines (tram)
• Nearby traffic lights, television sets, car motors, bike computers
• Nearby exercise equipment
• Nearby mobile phones +

12.5 Interference from other devices for measuring heart rates

The HR monitor as a receiver can react to interfering stray signals such as other heart rate
monitors within a vicinity of one metre. This can result in incorrect measurements par-
ticularly when training in groups. If you e.g. job next to one another, it can be beneficial to
wear the HR monitor on the other wrist or to increase the distance to one's training partner.
