Step-by-Step Installation

1. Adjust Latch (if needed): Hold the latch in front of the door hole. If the latch holes are centered, no adjustment is needed. If not, adjust the latch to 70mm (2-3/4in) by pulling and twisting the latch mechanism.
2. Install Latch: Insert the adjusted latch into the door edge. Ensure the square hole on the latch is horizontal. Secure it with screws.
3. Install Front Handle: Route the wiring through the square spindle. Insert the square spindle into the square spindle hole on the front handle, ensuring it fits squarely without tilting. Thread the square spindle through the square spindle hole in the lock body, ensuring it remains parallel.
4. Install Back Handle: Remove the battery cover from the back handle. Route the wire through the back panel. Fix the back handle with screw B.
5. Insert Batteries: Insert 4 AAA alkaline batteries (not included) into the battery compartment. Connect the wire on the battery box and ensure a tight wire connection. Install the battery cover back.

Operating Instructions

1. Unlocking Methods

• Fingerprint Unlock: Place your registered finger firmly on the fingerprint sensor. The lock will unlock if the fingerprint is recognized.
• Passcode Unlock: Enter your registered 6-10 digit passcode on the keypad. The lock will unlock upon correct entry. Utilize the anti-peep feature by entering random digits before or after your actual code to prevent others from guessing it.
• IC Card Unlock: Tap your registered IC card against the card reader area on the handle. The lock will unlock.
• Mobile App Unlock: Use the Tuya Smart app on your smartphone to unlock the door via Bluetooth when within range. For remote unlocking, a BIWIBON Gateway (sold separately) is required.
• Mechanical Key Unlock: In case of emergency or battery depletion, use the provided mechanical backup keys to unlock the door. The keyhole is discreetly located.

2. Smart App Features (Tuya Smart)

The Tuya Smart app provides comprehensive control and management over your BIWIBON Fingerprint Door Lock. Ensure Bluetooth is enabled on your phone and the lock is within range for direct connection. For remote features, a BIWIBON Gateway is required.

Maintenance

• Battery Replacement: The lock requires 4 AAA alkaline batteries. For best performance, we recommend using alkaline batteries. If you choose to use rechargeable batteries, do not charge them via the Type-C port, as this may damage the internal components. Replace batteries when the low battery indicator appears or when the lock's performance degrades.
• Cleaning: Wipe the lock's surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
• Emergency Power: In case of complete battery depletion, you can temporarily power the lock using a power bank connected via the Type-C port on the front handle to gain access.

Troubleshooting

• Lock not responding: Check battery levels and replace if necessary. Use the Type-C emergency power port with a power bank.
• Fingerprint not recognized: Ensure your finger is clean and dry. Try different angles or re-register your fingerprint in the app.
• Passcode not working: Double-check the entered code. Ensure the anti-peep feature is not causing confusion.
• App connection issues: Ensure Bluetooth is enabled and you are within range. For remote access, verify the BIWIBON Gateway is online and properly configured.
• Lock not engaging/disengaging properly: Check for any obstructions in the door frame or latch mechanism. Ensure the latch is installed horizontally.
• Factory Reset: If persistent issues occur, you may need to perform a factory reset. Refer to the app's settings under "Remove Device" and "Disconnect and wipe data". This will delete all registered data.
