What does the 'CHECK ATOMIZER' error message mean on my Xros 4 Nano?
The 'CHECK ATOMIZER' message indicates a no load or high resistance condition, and the device will stop working when this occurs. You should check that the pod is properly installed and that the connection pins are clean. (Page 6)
