1. I obtained the fingerprint setup flowchart from the property management. See Figure 1.
2. However, I did not know exactly what the administrator password was. I found the instruction manual, but it only listed a single reset password. See Figure 2.
3. In the registered passwords section of the instruction manual, I finally found information related to the administrator password. Under factory settings, when registering passwords, the first two sets of passwords registered are administrator passwords, and all the rest are user passwords. Since I had only registered one door-opening password, this password is theoretically the administrator password. See Figure 3.
4. Finally, I pressed my fingerprint 6 times, and the fingerprint setup succeeded. The previous password was 8 digits plus a final #, which required 9 key presses to open the door. Now with the fingerprint, I only need to press once to open the door. Compared to using a password daily, it is indeed much faster.
