This innovative padlock uses advanced biometric technology. It can set up two administrators; the first fingerprint and the second fingerprint. For the empty fingerprint status press 5S; enter the input state, then directly enter the first fingerprint (the first administrator). The second administrator must be authorized by the first administrator before the entry. Other fingerprints must be authorized by the first or second. After the authorization is done, the administrator can then enter any other finger print. Any fingerprint can unlock the padlock once the fingerprint is set. An illegal fingerprint cannot unlock this padlock. The red indicator flashes for 15 seconds when the voltage is equal to or lower than 3.5V, and alarms every minute if it is in low power condition. The red and green lights flashing alternately during the charging process.

Operational instructions:
1:First add fingerprints (managers): Long press and hold the lock beam for about 2 seconds. First a short blue light, then the green light flashed and released. Start to input fingerprints. Place the finger at the center of the fingerprint touch pressure. If it successfully collected data, it will flash a blue light. If not recorded or failed, it will flash a red light to remind the acquisition is invalid. After a total of ten successful acquisition, the lock beam automatically bounces off. Each person enters ten times.

2:Add fingerprints in the case of existing fingerprints: Press the lock beam for about 2 seconds, the blue light beams for one time, then loosens. When the blue light is long, enter the fingerprints of any of the two administrators(that is, the first or second fingerprints set). When the input administrator fingerprints is accurate, the indicator light changes from blue to green; then repeat the first step to add fingerprints.

3:Delete all fingerprints: Hold the lock beam for about 4 seconds with fingerprints. After the blue light is lit 2 times, the red light is released and the administrator fingerprint is input. The green light is lit and the fingerprint is deleted.

4:Lock: Press the lock beam in the unlocked state and lock immediately.
