Note: With the optoelectrical pulse measurement (photoplethysmography), whereby your blood
flow is recorded via green LEDs and photodiodes, the watch also displays values when the
watch is too loose or not being worn. For pulse measurement make sure therefore that the
strap is seated correctly.
Blood pressure measurement
The watch calculates blood pressure using an optical method (blood flow reflection), with
which precise values cannot be achieved. The precision of the measurements can vary from person to
person.
This is not a medical device: Data from the step counter, pulse and blood pressure functions
are not suitable for medical use.
Air pressure
Here, the current air pressure is shown in hPa.
Altimeter
The altitude is displayed here in metres. The altimeter is recommended for outdoor activities
where altitude changes play a role (e.g. hiking tours in mountainous regions). Before using the
altimeter, it should be calibrated via GPS. To calibrate the altimeter, tap "
Calibrate
" or press the lower
button once. The watch will now search for a valid GPS signal.
Note: For a valid GPS signal, you must perform the calibration outside with an unobstructed
view of the sky.
