2. Setup: Fingerprint Registration
Before using your padlock, you must register at least two administrator fingerprints. The first two fingerprints registered will be designated as administrators. These administrator fingerprints are crucial for adding or deleting other user fingerprints and resetting the device.
Initial Fingerprint Registration (Administrator):
- Touch the fingerprint identification area for 10 segons until the blue light is on.
- While the blue light is on, place your first finger on the sensor. The green light will turn on.
- Immediately after, place your second finger on the sensor. The green light will turn off, indicating that both administrator fingerprints have been successfully entered.
Important: The first time you use the padlock, you need to enter two different fingerprints consecutively. Ensure you enter your fingerprints from a 360-degree angle for better recognition.

Adding Additional User Fingerprints:
The padlock can store up to 10 fingerprints in total (including administrators).
- Unlock the padlock using an already registered administrator fingerprint.
- Press and hold the administrator finger on the sensor for 5 segons until the blue light is on.
- Press a new finger (the one you wish to add) on the sensor more than 10 times, ensuring the green light is on after each successful scan.
- Once the green light remains on, the new fingerprint has been successfully added.

It is recommended to register at least two administrator fingerprints immediately after purchase to secure the device.
Q: My fingerprint is not being recognized. What should I do?
A: Fingerprint recognition issues can occur due to various factors such as finger wear, peeling skin, scratches, dirt, moisture on fingers, or smudges on the fingerprint sensor. Ensure both your finger and the sensor are clean and dry. If you experience frequent issues, consider registering additional fingerprints (at least 3) to account for potential changes to your primary fingerprint.
Q: What if the battery dies completely?
