Precautions when using the adapter: 1. The output voltage(12V) of the adapter and the device must be the same, otherwise the device will be burned out or it will not work. 2. The output current(3A) of the adapter must be greater than the operating current of the device. Otherwise, the power adapter will "overcurrent" and burn out. 3. The DC output plug(5.5mm x 2.5mm) of the adapter must match the interface of the device, otherwise it cannot be connected. 4. The positive and negative polarity of adapter DC plug and device should be consistent to avoid accidents.
