3.3 Configuration initiale
After physical installation, the lock requires initial configuration:
- Set Administrator: The first user registered (fingerprint, password, or card) will typically be designated as the administrator. This user has privileges to add or delete other users.
- Ajouter des utilisateurs : Follow the on-screen prompts or voice guidance to add additional fingerprints, PIN codes, or RFID cards for other users.
4. Mode d'emploi
4.1 Déverrouillage avec empreinte digitale
Place your registered finger flat on the fingerprint sensor. The lock will unlock if the fingerprint is recognized.

4.2 Unlocking with PIN Code (Virtual Password)
To use the virtual password function, enter any random digits before and after your actual PIN code. This prevents others from observing your correct code.
- Example: If your correct PIN is 123456, vous pouvez entrer 0000 + 123456 + 0000 to unlock the door. The lock will identify the correct sequence within the longer input.
