Pattern Recognition
11. To TEACH the feature, drag a pattern recognition box around the chosen
feature. (Pattern recognition box: Move the cursor above and to the left of the
feature. Click and hold the mouse button, drag the box down below and to the
right of the feature, and release the button.)
The system moves the feature and pattern recognition locates it again. If the
system locates the feature go to Step on page -6. Otherwise continue on to the
next step.
12. If the pattern recognition program does not find the pattern, perform the
calibration again. If the system locates the feature, go to the results that are
explained in Step 14. If the system still does not locate the feature, use the
procedure for systems without pattern recognition as described in Step 13 and
Step 14.
