14. You will be prompted to teach the coordinates of the test area.
a. Teach the stripe with the best starting accuracy and click
Next.
If none are exact but one stripe starts too soon and the next too late, teach between
the two stripes. The wizard interpolates the values of the two.
b. Teach the stripe with the best ending accuracy and click
