Operating Instructions

Unlocking Methods
- Fingerprint: Place your registered finger on the fingerprint sensor. The lock will unlock if the fingerprint is recognized.
- Password: Enter your registered password on the keypad, followed by the '#' key (or equivalent confirmation key).
- RFID Card: Present your registered RFID card to the card reader area on the lock. The lock will unlock upon recognition.
- Mechanical Key: In case of emergency or battery depletion, insert the mechanical key into the keyhole and turn to unlock.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your smart door lock.
- Cleaning: Wipe the lock's surface with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and electronic components.
- Battery Replacement: When the battery low warning is indicated (audible alert or visual indicator), replace all four AAA batteries promptly. Do not mix old and new batteries or different battery types.
- Mechanical Parts: Periodically check the mechanical components (handles, latch, deadbolt) for smooth operation. Do not lubricate with oil-based products; use a graphite-based lubricant if necessary for internal mechanisms, but generally, smart locks are designed to be maintenance-free in this regard.
