PLEASE HELP ME for DAHUA HCVR 7208A-V2

[fraenkn 0]

I have a DVR DAHUA HCVR 7208A-V2, it is installed, and working fine, the problem is i forgot the password i set to it, so in case of a problem I cant log into it or check the cameras, to set it on my new phone. How can I reset it or something to the default. The other Accounts are deleted.

Remove BIOS battery has not helped.

PLEASE HELP ME

Thank you
