Calibrating the Compass Manually
Calibrate the electronic compass outdoors. To improve
heading accuracy, do not stand near objects that influence
magnetic fields, such as vehicles, buildings, and overhead
power lines.
Your device was already calibrated at the factory, and the
device uses automatic calibration by default.
If you experience irregular compass behavior, for example,
after moving long distances or after extreme temperature
changes, you can manually calibrate the compass.
1 Hold MENU.
2 Select Sensors & Accessories > Compass >
Calibrate > Start.
3 Follow the on-screen instructions.
TIP: Move your wrist in a small figure eight motion
until a message appears.

your activity involves changes in altitude, or the
Barometer option when your activity does not involve
changes in altitude.
Pressure: Sets how the device displays pressure data.
Calibrating the Barometer
