How to set your PIN

LDUVIN Official / High Quality Suitcase | K Type How to Set PIN
Initial setting

By default, the suitcase is set to open the suitcase with any fingerprint. Place your finger on the square fingerprint sensor. When your fingerprint is recognized, the green LED indicator will flash, you will hear a sound, and the lock will open automatically.
*If the LED does not blink and no sound is heard, the suitcase cannot be opened because the internal battery is insufficient. Charge the battery with a mobile phone charger or mobile battery before unlocking. We do not recommend using dedicated batteries such as fast chargers or computers.

lock and unlock

If the fingerprint authentication is successful, a voice sounds and the door unlocks automatically. A red LED will appear if the fingerprint authentication fails. Try fingerprint authentication again or use a different fingerprint to operate. After opening the suitcase, you can wait 2-3 seconds to re-lock it until the system resets.

fingerprint registration

① First, press the fingerprint button, the green LED flashes on the fingerprint sensor.
* After opening the suitcase for the first time, there is a slot for storing the battery inside the case. Put the battery in the slot.

② Press the fingerprint system button
After installing the battery, on the right side of the device (right side in the figure) is the control button for the fingerprint system. Quickly press the tip of the included plastic stick or pen into the small circular hole, and once it rings, a green LED on the fingerprint sensor will blink.

③Fingerprint registration (The same finger must be registered 9 times.)
Press the fingerprint of the finger you want to register on the fingerprint sensor, and release your finger when you hear a beep. Immediately press the same finger again, and release your finger when you hear a beep. Repeat this operation 9 times. After a long beep at the end, fingerprint enrollment for the same finger is complete. A maximum of 10 to 40 fingerprints can be registered.

*Note 1: Do not lock the phone immediately after completing 9 fingerprint registrations. After the LED turns off automatically, try the lock with your fingerprint to see if your fingerprint is registered successfully.
Note ②: After completing one fingerprint registration (9 times), if the green LED is still on, you can register another finger's fingerprint. You can register up to 10 to 40 pairs of fingerprints (may vary by model). If the maximum number of registered fingerprints is exceeded, the oldest fingerprints will be overwritten. We recommend always enrolling two or more finger prints as a backup.

Delete Fingerprint

After opening the suitcase, long press the tip of the included plastic stick or pen into the small circular hole and hold the button for about 8 seconds. Press and hold the button and the system will emit a "beep" sound followed by a long beep. When you release the button, the system will automatically turn off, batch delete all previously enrolled fingerprints and restore factory settings.
*Note: Please make sure the suitcase is open and check if the fingerprint is removed (try fingerprint recognition using any fingerprint). Anyone can open the suitcase with any fingerprint after restoring the factory settings.

Emergency unlocking method
Method 1: When you touch the pad with your finger, if the red light flashes as the lock is unlocked, the battery level is low. If you can't charge it, you can use the USB port on the fingerprint panel to connect to an external power supply to temporarily supply the battery and open the suitcase.
Method 2: If you can't charge while locked, you can use the backup key to open the suitcase.

 

The remaining battery capacity

①Battery level display
After fingerprint unlocking is completed, if the battery level is low, the red LED will flash and you will hear a "beep" sound. In that case, charge the battery immediately. After removing the battery, you can charge it directly with a charger with a USB port (or you can connect it directly to a power bank to charge it).
*Note: This product uses a lithium battery that is not compatible with commercially available quick chargers, and the battery may not be charged while it is green when using some quick chargers. Use a regular cell phone charger to charge. Our products come with replaceable batteries and should never be used in conjunction with other electronic devices. Other electronic equipment may be damaged.

②Charging method
You can use a power bank to directly charge the suitcase battery, or you can use a smartphone charger to charge the battery. Charging will be completed in about 40 minutes, and the red LED will turn green when charging is complete.

(3) Conforms to aircraft boarding standards
Suitcases generally meet airline boarding standards and can be carried directly onto the plane or checked in as hand luggage. In special cases, remove the suitcase's internal battery (capacity 180mAh), remove the battery and put it in your pocket during security check, then connect the battery to the suitcase's exterior USB port to power it and unlock it. Then put the battery back into the slot.

Smartphone charging function

There is a USB cable in the central zipper pocket inside the suitcase. By placing the mobile battery in the zipper pocket and connecting it with a USB cable, you can charge your smartphone externally via the USB port on the fingerprint panel of the suitcase.

Emergency charging method

If the built-in battery is completely dead (or there is no built-in battery), you can use the power bank connected to the USB port on the fingerprint panel to open your suitcase in an emergency.
