3. Registering Administrator Fingerprints
The first two fingerprints registered will be designated as administrator fingerprints. These are required to add or remove other user fingerprints.
- Press and hold the fingerprint sensor until the indicator light turns blue.
- Place your finger on the sensor. Lift and repeat several times, rotating your finger slightly each time, until the indicator light turns green. This registers the first administrator fingerprint.
- Repeat the process for the second administrator fingerprint.

3. Adding User Fingerprints (via App or Admin Fingerprint)
You can add up to 13 additional user fingerprints. This can be done through the app or directly on the lock using an administrator fingerprint.

Maintenance
1. Charging the Battery
The lock features a rechargeable Lithium-polymer battery. When the battery level drops below 10%, the red indicator light will flash rapidly during unlocking, signaling that a charge is needed. Connect the lock to a USB power source using the provided cable. A full charge can last for approximately 6 months in standby mode or over 1800 unlock cycles.

2. Cleaning
Wipe the lock body and fingerprint sensor with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components. Ensure the fingerprint sensor is clean for optimal recognition.
3. Water Resistance
The lock has an IP65 waterproof rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. While it can withstand rain and splashes, avoid submerging the lock in water for extended periods.
