4.1 Initial Charging

Before first use, ensure your padlock is fully charged. Connect the provided USB Android cable to the Micro USB charging port on the padlock and plug the other end into a USB power source (e.g., computer, wall adapter).

• The indicator light will illuminate red during charging.
• The indicator light will turn off when charging is complete.

4.2 First Use (Factory Default)

When new and not yet programmed, the padlock can be opened by any finger. This allows you to test the lock and proceed with fingerprint registration.

4.3 Registering Administrator Fingerprint

The first fingerprint registered will be designated as the administrator. The administrator fingerprint is required to add or delete other user fingerprints.

1. Ensure the padlock is unlocked.
2. Press and hold your chosen finger on the fingerprint sensor for approximately 5-8 seconds until the indicator light flashes blue.
3. Lift your finger and then place it on the sensor again. The light will flash green.
4. Repeat placing and lifting your finger on the sensor 5-10 times from different angles until the indicator light turns solid green, indicating successful registration.
5. If registration fails (e.g., light flashes red), repeat the process from step 2.

4.4 Registering User Fingerprints

After registering the administrator fingerprint, you can add up to 9 additional user fingerprints.

1. Unlock the padlock using the administrator fingerprint.
2. While the padlock is unlocked, press and hold the administrator finger on the sensor for approximately 5-8 seconds until the indicator light flashes blue.
3. Immediately, have the new user place their finger on the sensor. The light will flash green.
4. Instruct the new user to repeat placing and lifting their finger on the sensor 5-10 times from different angles until the indicator light turns solid green, indicating successful registration.
5. Repeat for any additional user fingerprints.

4.5 Deleting All Fingerprints (Factory Reset)

To delete all registered fingerprints and restore the padlock to its factory default state (any finger can unlock):

1. Unlock the padlock using the administrator fingerprint.
2. While the padlock is unlocked, press and hold the administrator finger on the sensor for approximately 10-15 seconds until the indicator light flashes red rapidly.
3. Release your finger. All fingerprints are now deleted. The padlock can now be opened by any finger.
