How to maintain Fingerprint Scanner

I believe many friends have had this experience. They excitedly bought a favorite Fingerprint Recognition Time Attendance device, but they didn`t know how to install it. They were also hesitant about whether to replace the door. The installation masters are very busy at the end of the year. If you can install the lock yourself, it will be a big deal. good. In addition, Fingerprint Recognition Time Attendance is also alive. The editor will tell you how to properly care and maintain the Fingerprint Scanner.

1. Before unlocking with fingerprint, warm your finger first
In winter, especially in northern areas, the weather is cold and the temperature is extremely low. At this time, Fingerprint Recognition Time Attendance also needs warmth. When the weather gets cold, the skin temperature of people's fingers will be relatively low, which will cause the fingerprint head of the Fingerprint Recognition Time Attendance system to be unable to sense the temperature of the fingers; or if the fingers are too dry in winter, the fingerprints will not be able to sense normally.
In this case, you need to rub your hands together before opening the door, or breathe hot air on your fingers to "cover" them to warm them up. This will restore your fingers to a certain temperature and humidity, and the Fingerprint Scanner can Responded normally.
2. When opening the door with a mechanical key, do not add lubricating oil indiscriminately
If you do not use the mechanical key to open the door for a long time, the lock key may not be inserted and removed smoothly. At this time, you can pour a little graphite powder or pencil powder into the lock cylinder slot to ensure that the key can unlock the lock normally. Be sure not to add any other grease as a lubricant, because it will easily stick to its internal mechanical components, especially in winter, and the lock will not be able to rotate or open.
3. Regularly clean up the Fingerprint Scanner surface
If the Fingerprint Scanner surface is used for a long time, the surface will be stained with dirt or the surface will be moist, affecting the normal sensing of the Fingerprint Scanner. At this time, gently wipe the surface of the Fingerprint Scanner with a dry and soft cloth.
4. Replace batteries regularly
When a low battery alarm occurs, remember to replace the battery with a new one immediately to ensure normal use of the door lock.
5. Do not hang heavy objects on the handle
The handle is a key part of the Fingerprint Scanner. You rely on it to open the door. However, you cannot hang heavy objects on the handle. Friends who have this habit must change it. Because over time, the handle becomes inoperable.
6. Regular physical examination of the lock body
Fingerprint Scanner, like people, need to be treated with care and love. Therefore, regular physical examinations are necessary. At least a physical examination of the lock every year, and check whether the screws are loose or falling off to ensure it is strong and safe.
