Operation Manual

Compass calibration screen
When compass calibration is started, sweep the device through a
figure 8 pattern to calibrate the compass. The device signals, if the
calibration was successful or not.
Note: The compass calibration might not succeed at the first attempt. Please,
try to repeat the operation whenever you have the impression that the
compass is not orientated correctly.
3.7.4.2. Barometer
Barometer calibration
The built-in Barometer sensor is used to provide you information about
the altitude variations during your activity.
This sensor needs to be calibrated, setting an initial altitude value that
might come from the GPS or it can be set manually, if you know the
exact altitude of the place where you are.
When the sensor is calibrated, ‘Calibrated’ text will notify you.
Recalibration can be achieved by pressing the ‘Reset button’.
If you want to enter the altitude manually, select ‘Manual’, then press
the height button (default: ‘0m’), and insert the desired value.
