2.2 Calibrating the compass
In order for your track to be correctly aligned even when stationary, the compass must be calibrated at regular
intervals. To do this, open the quick menu at the beginning or during the training session and select “Calibrating the
compass”. Follow the instructions on the display. Calibration works best if you turn by 360° with the watch on your arm.
2.1 Calibrating altitude sensor
The altitude measurement of the iD.FREE / iD.TRI is determined on the basis of the barometric air pressure.
Any change to the weather means a change to the air pressure, which can lead to a change to your current altitude.
To offset these changes in air pressure, you must enter a reference altitude into the iD.FREE / iD.TRI (process
known as calibration).
The watches offer you three different types of calibration. To do this, open the quick menu at the beginning or during
the training session:
1.
Home
The home altitude is set in the device settings. Choose this value if you often start training at the same place.
2.
GPS
If you do not have a reference point or any indication of your current altitude, you can calibrate this by means
of GPS. The accuracy of the displayed altitude depends on the GPS receiver.
3.
Manual calibration
Use this setting if you know the current altitude.
2.3 Setting and calibrating the power meter
To set your power meter, first connect the power meter to the watch (as described in “Connecting sensors /smart
phone”). Then select “Settings > Connection > Sensors > Connected sensors”. If your power meter offers the
corresponding setting options, you can then set the corresponding data (e.g. crank arm length) by pressing the
“+” button. To do this, you must be near the power meter and it must be switched on /activated. If your power meter
supports additional settings, please refer to the instructions of the manufacturer of the power meter.
To reset the power meter before or during the training session, do the following:
►
Start a training in the CYC profile
►
Open the quick menu (press and hold the “+” button for 2 seconds).
►
Select “Power Meter Zero Off” and perform the procedure as specified by your power meter manufacturer.
You see this menu item only when the power meter is connected. If you like to see the power values during
the training, you have to adjust the CYC sport profile accordingly.
