Help please. I purchased a used Speco D16VT8TB on eBay. I'm trying to set it up and see that the ADMIN password has been changed from the default (1111). Any idea how to change it? I tried pulling the CMOS battery but that just reset the clock. I am able to access USER 1 with the default password,but it will not let me restore factory defaults or view log! I've reached out to Speco but they don't seem to want to help. Any ideas? Is password stored on the hard drive?
