Check the bottom of the base for debris, and wipe it with a clean, dry cloth.

Wipe your screen with a soft, dry cloth to ensure the best conductivity with the figure.

Make sure you are holding the figure in the right location in order for it to be recognized.  Hold it on the sides of the base where the black indented finger grips are.  Do not wear gloves or mittens since the base needs to come in contact with your fingertips.

Make sure that you are not placing the figure on the black or white frame around the iPad screen. You must keep the figure only within the screen area.
