4. Operating Instructions

4.1 Tuya App Setup and Management

The Tuya Smart app is essential for managing your lock's features, including user registration, passcode generation, and activity logs.

1. Download the Tuya Smart app from your device's app store.
2. Create an account or log in.
3. Add your smart door lock by following the in-app instructions. Ensure Bluetooth is enabled on your smartphone.
4. Once connected, you can manage users, generate various types of passcodes (permanent, one-time, recurring), and view access records.

Note on Wi-Fi Connectivity and Smart Home Integration: For remote Wi-Fi control, real-time alerts, and integration with smart home platforms like Amazon Alexa or Google Assistant, a compatible Tuya Gateway/Hub (sold separately) is required. The lock connects to the app via Bluetooth directly; the gateway bridges the lock to your Wi-Fi network.

4.2 Unlocking Methods

• Fingerprint: Place your registered finger on the fingerprint sensor. The lock will unlock if the fingerprint is recognized.
• Passcode: Enter your registered passcode on the keypad, then press '#'. The lock supports anti-peeping functionality, allowing you to enter random digits before or after your actual code to prevent others from guessing it.
• IC Card: Present a registered IC card to the card sensing area on the keypad. The lock will unlock upon recognition.
• Physical Key: Insert the physical key into the mechanical keyhole and turn to unlock. This is an emergency backup method.
• Tuya App (Bluetooth): Open the Tuya Smart app on your smartphone and tap the unlock icon when within Bluetooth range of the lock.
• Tuya App (Wi-Fi - with Gateway): If a gateway is connected, you can remotely unlock the door from anywhere via the Tuya Smart app.

4.3 Automatic Locking

The lock features an auto-lock function that can be configured via the Tuya app. You can set a delay time (e.g., 5-900 seconds) after which the door will automatically lock once closed. This provides peace of mind, ensuring your door is always secured.

5. Maintenance

5.1 Battery Replacement

The smart door lock is powered by 4 AA alkaline batteries (not included). When the battery level is low, the lock will provide an indicator light alert and/or an audible warning. It is recommended to replace all four batteries simultaneously with new, high-quality alkaline batteries.

Emergency Power: If the batteries completely drain, you can use a USB-C cable to connect a power bank to the emergency power port on the exterior unit to temporarily power the lock and gain entry.

5.2 Cleaning

Clean the lock's exterior surfaces with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or electronic components.

6. Troubleshooting

• Lock not responding: Check battery level. If low, replace batteries or use the USB-C emergency power. Ensure the lock is properly installed and all cables are connected.
• Fingerprint not recognized: Ensure your finger is clean and dry. Try re-registering your fingerprint in the app. Ensure the sensor is clean.
• Passcode not working: Verify the correct passcode is entered. Ensure you are pressing '#' after the code. Try generating a new passcode in the app.
• App connection issues: Ensure Bluetooth is enabled on your phone and you are within range. Restart the app and/or your phone. If using Wi-Fi, ensure your Tuya Gateway/Hub is properly connected and online.
• Lock beeps continuously or behaves erratically: This may indicate a low battery or an installation issue. Check batteries first. If the problem persists, consult the full manual or contact support.
• Door does not lock/unlock mechanically: Check for any obstructions in the door frame or latch. Ensure the mortise is correctly aligned and installed.
