Horizontal calibration• : Calibrate the geomagnetic
sensor when the compass or augment reality application
shows incorrect information.
Keep the touch screen or keypad facing up during •
calibration.
Calibration may take some time, depending on •
your location or other circumstances.
Calibration may not be possible in areas with •
strong magnetic elds. If the calibration fails, move
to another area and try again.
If you enter an area with strong magnetic elds •
after calibration, your device will automatically
attempt to recalibrate the geomagnetic sensor.
The geomagnetic sensor in your device does •
not support the bird’s-eye view, which xes the
directions. Therefore, a small error may occur in
measuring angles and cause a map to be turned
upside-down.
