11/ Troubleshooting
11.1/ Abnormal heart rate
You have noticed large fluctuations in your heart rate.
Check that the strap is in place and the sensors have been moistened (diagram 1, page 1)
Interferences in the environment due to electromagnetic disturbance can make heartbeat readings
temporarily unstable or inaccurate. This often occurs close to high voltage lines, railway power lines,
traffic lights, televisions, car engines, some motorised sports equipment, cell phones, computer screens,
microwave ovens and when you pass through electric safety gates.
There are other causes for altered heartbeat readings:
- Clothes that chafe on the strap or are full of static electricity.
- Very hairy chests
- Dirt on the strap
If heartbeat readings are unstable, first check that none of the causes above are responsible for the problem.
11.2/ Detecting the strap
If the does not flash:
- Move the strap closer to the watch.
- Adjust the position of the strap and moistening the sensors further.
- Check that the batteries are working, especially in the strap.
- In CARDIO or CALORY mode Synchronise the watch by holding down the MODE button . ( see Chapter
5.1)
If the link with the strap is broken temporarily, a heart rate of 0 is displayed on the main line.
If the link is broken for more than five minutes, the display changes to ---. To reactivate the
signal search, hold down MODE for 3 sec or exit CARDIO mode by pressing MODE then
return to CARDIO mode. . The search will begin again. ( see Chapter 5.1)
E.g.: A 30-year-old athlete training using aerobic endurance to increase their resistance to effort and improve
their half marathon time. The most effective training area for her objective will be the resistance zone.
