Q: The Motion Wake function is not working, what should I check?
A: Please make sure the physical On/Off switch is not set to “Off.” The device must be clipped securely in place and sufficiently charged. Motion Wake is triggered by vibration (for example, when opening a car door), so if the car environment is very stable, the wake-up may not activate automatically.
