1. In daily life, we should ensure that the fingerprint head is clean and tidy. Regularly check the technical status of the lock body. When collecting and inputting fingerprints, the finger strength is moderate. Do not exert great pressure. Wipe the dust of the fingerprint acquisition window with a mirror cloth, because there will be dirt on the surface after a long time, which may affect the normal use. Never clean the fingerprint lock with a wet rag or a cleaning ball, as it is easy to damage the electroplating layer on the surface of the fingerprint lock. Conduct self-test every 3-6 months on average, deal with abnormalities in time, fasten and adjust loose and misaligned parts, and change some vulnerable parts for preventive purpose.

2. Contact with water or other liquids or immersion in water or other liquids should be avoided as far as possible. If the shell comes into contact with liquid or salt spray, wipe it dry with a soft and absorbent cloth.

3. Pay attention to battery replacement. When the battery power of the smart lock is low, it will be notified at least two weeks in advance. Please charge it in time to avoid affecting the normal use.
