2. Disconnect the external power supply and watch the alarm message that can receive the power failure or the buzzer that hears the alarm.
If the above two steps are normal that is the indicator light of the power supply is broken. 
If the equipment is normal, you can contact King Pigeon relevant personnel to solve the problem. Please contact us before above two steps have been done and tell the test results.

Immediately after the device is powered off, the buzzer will sound and alarm. After a period of time, the buzzer will not sound and all the indicators will be off after the power is turned off.
Replacement of a new power adapter charges the device for half a day, and then power off again to see if the indicator light of the device will turn on or whether the buzzer will ring. If the indicator light will turn on and the buzzer will ring, it means that the power adapter is broken. If change a new power adapter still doesn't available,that means the battery of the device is broken. Please contact King Pigeon's technician.
