TROUBLESHOOTING
The watch does not display the heart rate. Check if:
- the chest belt is positioned correctly
- the chest belt electrodes are wet and in contact with
the skin
Heart rate detection is inconsistent or stops:
- replace chest belt battery
- electromagnetic fields can cause interference
Heart-rate monitor beeps continuously:
- if Target Zone alarm is activated, the acoustic signal
indicates that heart rate is out of the Target Zone chosen
(see page 7)
Display and/or functions are blocked:
this may happen due to static electricity or after battery
replacement. Press and hold all 4 buttons simultaneously
to reset the device to factory settings.
