I want to upgrade to new version of firmware.
1. Put USB thumb-drive in any USB port of DVR that shall be compatible with USB 2.0 version
2. Once the system detects the thumb-drive, user can see a brand or model name of it in "DEVICE"
after pressing "SCAN" button.
3. Click "SCAN" button to get DVR recognize usb device, and click "OK" to confirm.
It is recommended to proceed "HDD Format" after finishing the upgrade of firmware, because the data recorded by previous firmware may cause malfunction of DVR due to different format. The data is not going to be deleted.
When you upgraded firmware you have to reset the time or date again.
