7. Use the stylus to draw each of the 9 vertical lines. Start by placing the stylus at the entrance to the
guide lines and draw towards the top of the screen. The small square below the guide lines will
turn green to indicate that the data for that line has been captured.
8. If any of the lines turn red instead of green, the line can be redrawn.
9. If any of the lines curves at the top and the line turns red, press F2. This will straighten the curved
part of the line
10. Note that it is OK for the line to be at an angle or to lie outside of the guide lines – provided the
line is straight along its length this is acceptable. Then re-calibrate and redraw the lines again.
11. Touch the top corners of the screen until the indicators turn green (shown as small squares in the
screenshot above).
12. Draw along the corner lines indicated at the bottom of the screen until they turn green.
Note: draw down the side and then along the bottom edge towards the centre for each corner.
