1. Squeeze the adapter of your choice (S or M) into a heart shape to insert it into the Ring.
2. Slide the Ring on your drawing tool and adjust it to be around 4cm from the pen tip and perpendicular.
Once the Ring is placed on your tool, you need to calibrate the Ring to increase the precision and improve your experience. To make it:
1. Press and hold the top button, a pink LED breathes.
2. Press the tip of your pen at the center of your Slate then release the button.
You can now use your tool effectively with your Slate. Don't forget to renew the calibration step each time you change your tool.
