matters needing attention:
1. What if the fingerprint cannot be identified?
Generally, fingerprint identification is not successful, which is usually caused by abrasion, peeling, scratch and dirt
Fingers are too wet, or there are dirt and water drops at the fingerprint collection port. Fingers and fingerprints must be guaranteed
Only when the window is clean and dry can the recognition be successful.
In case of finger scratch, it is recommended to enter at least 3 fingerprints after purchase.
2. How many fingerprints can be entered?
Two fingerprints must be registered consecutively for the first time, and eight fingerprints can be added later.
3. What if the battery is dead?
Connect the charging port with USB, and the red light is on, indicating that it is charging
Unlock normally. When the light is off, it means it is fully charged.
4. How long can it last when fully charged?
It can stand by for 12 months when fully charged, and the lock will flash red when the battery is low.
