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.
• Make sure that you 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 field, for example, calibrate in an open
field.
