Operation / Procedure
Moisten the electrodes using conducting aqueous gel or water.
Check the positioning of the belt around your chest: it should be positioned
as shown in the instruction leaflet.
Bring the HRM watch and the belt closer together, check the above points,
and then check transmission. If there is no transmission, change the belt
battery as shown in the instruction leaflet.
Please visit a DECATHLON workshop to have your HRM battery changed.
You may be in an area with a strong magnet field, a high voltage power line,
radio communication equipment, etc.
If this is the case, move away from this area.
The belt does not have a coded transmitter. You will receive interference
when less than 1 metre from other HRM users.
Check that the belt is tightened and that the electrodes are moistened.
Rubbing of the belt sends a signal different to that of a heart rate.
During cold and dry weather, the product may give incorrect information for a
few minutes. This is normal, as a film of perspiration is necessary for good
contact between the electrodes and your skin.
For around ten seconds, the displayed value may be inconsistent with your
real heart rate. This is because the algorithm is initialising.
Hold down buttons S1, S2, S3 and S4 together for 1 second to RESET the device.
Now set the device as shown in the instruction leaflet.
The target zone alarm is probably active and you are outside of the zone.
See the instruction leaflet for details of how to set or deactivate the target
zone alarm.
