Signals from other chest straps in the vicinity of less than 2metres / 6foot 6
inch may cause incorrect values
Why is the heart rate monitor displaying a heart rate that is fluctuating / too high?
This can be caused by:
-
Electromagnetic disturbances, eg. From high-voltage lines (above and below
ground), overhead cables, electric motors, car motors, mobile phones, other
training devices, etc.
-
Fluctuations in heart rate are absolutely normal. The heart rate can fluctuate
daily, it depends on many factors.
The heart rate monitor display has frozen / no longer responding?
Reset the heart rate monitor if the display is “frozen” or irregular symbols appear:
-
Press and hold the SEL and SET button simultaneously for approx. 3 seconds.
All display segments will briefly appear and you will reach the default settings
again (see section
SETUP
)
-
Alternatively: Remove the battery and insert it. This will reset the
microprocessor
-
Please pay attention to the small spring protruding from the movement.
Handle it carefully so that this spring is not lost.
After this the heart rate monitor should function normally again.
The display is weak, barely readable, what can I do?
Replace the battery as soon as the display becomes weaker or fades entirely. When
inserting the new battery, always pay attention to the correct polarity. If the battery
needs to be removed and reinserted, the personal data will need to be re-entered.
Why is the display light not working?
Is the battery depleted? Please check the battery. If it is depleted, replace it with a
new one (3V / CR2032). Please pay attention to the correct polarity.
Why is an incorrect average heart rate displayed after training?
This is probably because you did not stop the timer (stopwatch) in heart rate mode,
and are no longer wearing the chest strap. In this case, the heart rate monitor is no
longer receiving a heart rate from the chest strap, and because the timer is still
running the watch is calculating with the heart rate value of 0. This means that the
