Recovery (Power Failure)
If the NVR crashes, restart the machine to resume the working condition.
If the NVR is shut down abnormally during recording, the current recorded
data might be lost.
Replacing the Button Cell Battery
It is recommended to use Lithium batteries of the same type (CR2032) to replace the old one.
To ensure the accuracy of the system time, replace the Lithium battery every two years.
Replace the battery when the NVR is powered off and then reset the system time after
restarting it.
