•
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 fields. If the calibration fails, move
to another area and try again.
•
If you enter an area with strong magnetic fields
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 fixes the
directions. Therefore, a small error may occur in
measuring angles and cause a map to be turned
upside-down.
