1. Place the drawing on the tablet.

2. Attach the tablet firmly to prevent it from shifting during digitizing. If it shifts, no existing data is lost, but you must calibrate the tablet again.

3. Press C to switch to Calibration mode.

4. Press A to select the calibration type.

5. Select Simple for linear stretch in both horizontal and vertical directions.

6. Digitize the lower-left, upper-left, and lower-right corners (the minimum needed to locate the drawing on the tablet).

7. Select Mesh for warpage or nonlinear stretch of the drawing.

8. Specify the number of horizontal and vertical points to calibrate.

9. Press C to show the appropriate calibration type in the dialog box. If you select Mesh, specify the number of points in the vertical and horizontal direction pressing the 0–9 buttons to specify values for height and width. Press D to specify a decimal point.

10. Specify the number of horizontal and vertical points to calibrate. The most simple (2 points in each direction) enables linear stretch in both horizontal and vertical directions.

11. Digitize the points for three corners of the drawing first. Press 0 to pick the point. One of the grid points that is closest to the cursor highlights. If this is the correct grid point, press 0 to confirm or 3 to cancel. If you need to select another grid point instead, move the highlight to another grid point.

12. If you select Mesh calibration, a grid pattern appears on the screen delineating the corners of each calibration area.

13. Press 0 to pick a calibration mark on your drawing. One of the grid points that is closest to the cursor highlights. If this is the correct grid point, press 0 to confirm or 3 to cancel. If you need to select another grid point instead, move the highlight to another grid point.

14. Continue to calibrate all areas.

15. Press C to switch to the next mode.
