5. Operating Instructions
5.1 Adding User Fingerprints
Up to 100 fingerprints can be stored in total (including the administrator).
- Wake up the lock by touching the sensor or pressing a button (if available).
- Place the administrator's finger on the sensor. Once recognized, the indicator light will turn blue.
- Immediately after, place the new user's finger on the sensor. The indicator light will flash.
- Lift the new user's finger and place it again, repeating this process approximately 5-10 times from different angles until the indicator light turns green, indicating successful registration.
- To add more fingerprints, repeat steps 2-4. If no further fingerprints are added, the lock will exit registration mode after a short period.
5.2 Deleting All Fingerprints
This action will delete all registered fingerprints, including the administrator's. The lock will revert to factory settings, requiring a new administrator fingerprint registration.
- Wake up the lock.
- Place the administrator's finger on the sensor. Once recognized, the indicator light will turn blue.
- While the light is blue, press and hold the registration button (or specific reset button) for approximately 5-10 seconds until the indicator light flashes red, then turns green. This confirms all fingerprints have been deleted.
- You must now register a new administrator fingerprint as per Section 4.3.
5.3 Locking and Unlocking
- To Lock: The lock automatically locks when the furniture is closed. Some models may require a brief touch on the sensor to engage the lock.
- To Unlock: Place a registered finger on the fingerprint sensor. If the fingerprint is recognized, the indicator light will turn green, and the lock will disengage. If the fingerprint is not recognized, the light will flash red.
