Registering for the first time
1. Unlock the lock using the finger you want to register and keep the finger on the scanner until the blue light turns on.
2. Press the same finger on different positions about 10 times until the green light turns on. If you press the same position twice, the light will turn red.
3. To register a second fingerprint, repeat the above steps when the green light is on. The registration is successful when the green light turns off.
Registering additional fingerprints
1. Unlock the lock using any registered finger and keep the finger on the scanner until the blue light turns on.
2. Press the new finger on the scanner several times until the blue light turns off.
Emergency Code Setting (Recovery Code)
1. After registering the fingerprint, unlock the lock and keep the finger on the scanner until the light turns white. Then, release the finger, and the light will turn green.
2. When the light turns green, start setting the first number of the Recovery code by pressing the finger on the scanner the required number of times. For example, to set the first number as 5, press the finger on the scanner five times. Wait for the light to turn blue.
3. When the light turns blue, use the same finger to set the second number of the Recovery code by pressing the finger on the scanner the required number of times. For example, to set the second number as 6, press the finger on the scanner six times. Wait for the light to turn off.
4. Remember the numbers you set on green and blue lights as they represent the Recovery code.
Emergency Code Unlock (Recovery Code)
1. If none of the registered fingerprints can unlock the lock, use any registered finger to press the scanner until the light turns white. Release the finger, and the light will turn green.
2. When the light turns green, press the first number of the Recovery code. Wait for the light to turn blue. Then, press the second number of the Recovery code. If the numbers are incorrect, the light will turn red and flicker. Repeat the above steps with the correct numbers until the lock unlocks. After unlocking with the Recovery code, the lock restores to the factory settings.
3. If you did not set the Recovery code, the default setting is 33 (press the scanner three times on the green light and three times on the blue light).
Restore Factory Settings
1. Do not remove the finger from the scanner after unlocking until the red light turns on.
2. When the red light turns on, release the finger. All the registered fingerprints and Recovery codes will be removed, and the lock will restore to the factory settings.
