Precautions about bidirectional calibration
•
You can use any two opposing directions for bidirectional calibration. You must, however, make sure
that they are 180 degrees opposite each other. Remember that if you perform the procedure
incorrectly, you will get wrong bearing sensor readings.
•
Do not move the watch while calibration of either direction is in progress.
•
You should perform bidirectional calibration in an environment that is the same as that where you plan
to be taking direction readings. If you plan to take direction readings in an open fi eld, for example,
calibrate in an open fi eld.
To perform bidirectional calibration
