You will need to take this apart to do this in this case since you dont know the password.
IF you are able to take the system apart, we can locate a on board battery -- like a "quarter sized 1.5 volt BUTTON STYLE" battery. This will need to be removed from the mother board, terminals shorted out, and *possible* reset micro switch on the motherboard. There are various FIRMWARE versions for the L23WD960 "series" so exact steps and even mother board locations may vary . The NET of this is that , since ADMIN password ***** not provided with your purchase,(designers & installers for security purposes try to prevent
vent "DVR whipe out" in case of a theft, violation etc.to potect the OWNER's interest as best practice) IF the above BIOS LEVEL RESET does not work, this means, simply, a factory return for DEFAULT EPROM,- a level of security to , again protect the OWNER from a less than honorable employee, etc from removing critical DVR files by simply changing / erasing.
In any case, I will stick with you until this is complete.
