Dash Cam Pro has a built-in battery. It is only used to supply power for final video storage when the device is turned off and during parking surveillance. Please do not use the Dash Cam Pro without an external power supply or disassemble the built-in battery by yourself.
If the device has not been used for a long time, the battery may be depleted. It still can be used when it is connected to the power, but the system time may be reset to the factory default. Please reset the system time after turning on the device.
When the battery is low, the device cannot be turned on without external power supply. Please turn it on after connecting it to the external power.
In case of any high temperature, deformation, expansion or liquid leakage of the battery, please stop using it immediately and contact the after-sales service center.
