Use a suitable battery, preferably the one recommended by the manufacturer. In addition, when using the Fingerprint Lock, the user should try to use the same type and brand of batteries, and do not use different brands and different types of batteries.It is forbidden to contact the panel with corrosive substances to prevent damage to the surface coating.Do not hit or knock the casing with hard objects to prevent damage to the surface coating of the fingerprint combination lock.Fingerprint locks basically have built-in sophisticated electronic components, which may damage internal components or cause other serious consequences when disassembled by non-professionals. If you suspect that there is a problem with the fingerprint combination lock, it is best to consult a professional, or directly ask someone to come and repair it. If you are going to go out or not use the lock for a long time, please bring the mechanical key and remove the battery to ensure the service life of the lock. When collecting fingerprints, the finger strength is moderate, do not exert strong pressure.Because the fingerprint combination lock contains a lot of electronic devices, if water enters, it will interfere with the electronic circuit, etc., so the Fingerprint Lock should pay attention to waterproofing.After the door lock has been used for a period of time, when the battery power is low, the buzzer will emit a "Di Di" low-voltage alarm every time the door is opened. At this time, please replace the battery in time and pay attention to the installation of the positive and negative electrodes to ensure the normal use of the lock.For users with flat and thin fingerprints or younger users, it is recommended that you register your fingerprints with your thumb, and register more than 2 fingerprints for the same user to improve the success rate of fingerprint collection. Do not pull the slide cover, push it open and close with force, and use the slide cover correctly.Do not use substances containing alcohol, gasoline, thinner or other flammable substances to clean or maintain the fingerprint lock. Use a soft cloth to wipe the dirt on the fingerprint collection window, because after a long time of use, there will be dirt on the surface, which may affect normal use.

Fingerprint lock is a kind of intelligent lock with human fingerprint as identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The above is all the knowledge about the use of Fingerprint combination Locks and the precautions for the use of fingerprint combination locks that I introduced to you today. I hope it can help you.
