Fingerprint Setup:

Setting up this lock is very similar to setting up a fingerprint on a smartphone.

1. Use any finger to enter the fingerprint recognition port. The green LED flashes while you hear two sounds. It will unlock.

2. Within 5 seconds after unlocking, when the green LED is on, put the finger that you want to enter as your fingerprint on top of the fingerprint recognition port for 4 seconds. You will hear a sound, that means you entered the input mode. Lift off your finger.

3. Use the same finger to press 8 times continuously and you will hear a sound every time. The last time when you hear two sounds, lift off your finger. After 10 seconds, the LED will go out and the recording will be completed. Now you can use your fingerprint to unlock.
