Fig 5
2. You will see the following screen (Fig 6); there are three targets to touch in total, like the one
shown below:
Fig 6
3. When each of these targets is displayed, touch and hold your finger on the centre of the
circular target. You must touch all three targets in turn.
4. The red circle in the target slowly moves towards the centre of the target.
5. Remove your finger only when the next target appears and touch that one.
If the touch calibration is not correct after this procedure, please run the process
again and adjust your finger position on the targets to compensate for the misalignment.
