Troubleshooting the codes
0x00: Check in Settings>System>Auto Maintain to ensure that the DVR is not set to reboot.
0x01: This one is the hardest one to diagnose. We recommend updating the firmware to the most recent found here, hard resetting the DVR, and ensuring the DVR is receiving consistent power.
0x02: Clear the log. Go to Information>Log and click Clear.
0x03: Check in Settings>Storage>HDD Manage and look at the Status. If it is not "Normal", it is likely that there is a hard drive error and it needs to be replaced.
0x04: Check all of the camera connections and ensure they are powered correctly.
0x05: Check in Settings>Storage>HDD Manage and look at the Status. If it is not "Normal", it is likely that there is a hard drive error and it needs to be replaced.
