About Altitude Calibration:
1. If you are aware of your home altitude or basis altitude before riding, you can
directly adjust the current altitude data after you enter this mode.
2. If you do not know your basis altitude before riding or if you do not care
about the altitude of the starting point, you may return the current
altitude value to zero in the calibration mode by pressing both A and B
buttons at the same time briefly. In this way, the rider will still enjoy the
fun of learning the accumulated altitude gains during each ride.
