Rotate the cylinder until the LEDs light up (in either direction).
Rotate it in the opposite direction until the LEDs light up again.
Repeat this 5 times. The LEDs should light up a total of 10 times within 8–20 seconds.
When the restart begins, the cylinder will blink blue four times, followed by one white blink. After this, you will hear a mechanical sound, indicating that the cylinder is restarting.
