Trouble Shooting

Problem01 : The device does not switch when the ON/OFF button is pressed.

How to proceed:
The device runs out of battery. Please charge with a 12V 2A adapter for 3 hours before using again. When the LED stays green, it means it is fully charged. Problem02: The device shut down after working for a while.
