6.3 Duress Fingerprint Alert
For emergency situations, you can pre-set specific fingerprints as duress fingerprints. When one of these is used to unlock the door, the lock will silently make a call to a pre-configured phone number for notification, without alerting the person unlocking the door.
7. Maintenance
7.1 Battery Management
The door lock is powered by 8 No. 5 (AA) batteries, providing up to 1 year of battery life. The Mi Home APP will provide thoughtful reminders when the battery level is low. In case of complete battery depletion, a Type-C external rechargeable battery can be used to provide emergency power for temporary unlocking.
- Battery Replacement: When the low battery alert is triggered, replace all 8 batteries with new ones of the same type.
- Emergency Power: Connect a Type-C power bank or adapter to the emergency power port on the lock to temporarily power it for unlocking.
7.2 Cleaning and Care
- 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.
- Keep the fingerprint sensor clean and free of dirt or moisture for optimal performance.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock not responding / No power | Dead batteries | Replace all 8 No. 5 batteries. Use Type-C emergency power if needed. |
| Fingerprint not recognized | Finger dirty/wet, sensor dirty, unregistered fingerprint | Ensure finger and sensor are clean and dry. Re-register fingerprint if issue persists. Consistent use improves recognition. |
| Mi Home APP connection issues | Incorrect APP region setting | Change Mi Home APP region to "Chinese mainland" in settings. |
