Problem
1 – There is no
heart rate display.
2 – The watch display is
weak or illegible.
3 – The displayed heart rate
is erratic or is
really too high.
4 – The heart rate displayed
at the beginning of the wor-
kout is inconsistent.
5 – The product is malfunc-
tioning.
6 – When the heart function
is used, the device
beeps.
Cause
1.1 – The electrodes are not moistened properly.
1.2 – The chest belt is not positioned correctly
1.3 –The battery of the chest belt is weak or
not working.
2.1 – The battery of the heart rate watch is
weak.
3.1 – The device is receiving interference.
3.2 – You are receiving the heart rate data of
another runner.
3.3 – Friction of the chest belt
3.4 – Poor conductivity during dry
and cold weather
4.1 – The algorithm is initializing.
5.1 – The buttons are not activating the right
functions and the device seems to
be malfunctioning.
6.1 – The target-zone alarm is not
programmed properly.
Operation / Procedure
Moisten the electrodes with water or a conductive water-based gel.
Check the position of the belt on your rib cage,
as shown on the drawing in the owner's manual.
Bring the heart rate monitor watch closer to the chest belt you are wearing,
and once you have checked the two points given above, check that
transmission has been established. If necessary, change the battery of the
chest belt as indicated in the owner's manual.
To have the battery of the heart rate monitor changed, contact the appropriate
DECATHLON department.
You might be in an area with a strong magnetic field, a high-voltage line, a
catenary, radio-communications equipment etc.
In this case, keep away from this area.
The chest belt does not incorporate coded transmission technology.
Interference may occur if you are less than one meter away from other peo-
ple wearing heart monitors.
Check that the chest belt is tight enough and that the electrodes are well
moistened. Friction from the belt sends a signal that does not correspond to
the heart rate.
When the weather is dry and cold, the product may emit erroneous infor-
mation for a few minutes. This is normal, because a film of sweat is neces-
sary to ensure proper contact between the skin and the electrodes.
For a several scores of seconds, the value displayed may not correspond to
your actual heart rate. This is due to the initialization of the algorithm.
Activate the RESET function by pressing on all four S1, S2, S3 and S4 but-
tons simultaneously for 2 seconds. Then follow the setting procedure as indi-
cated in the owner's manual.
The target-zone alarm is probably activated and you are out of the zone.
Refer to the owner's manual for setting the zone or turning off the target-zone
alarm.
