3. Setup
3.1. Battery Installation
The ABUS YARDO 7807F requires one CR2 battery for operation. A battery is included with your purchase.
- Locate the battery compartment cover on the lock body. This is typically secured by a small screw or a latch.
- Using a suitable tool (e.g., a small screwdriver), carefully open or remove the battery compartment cover.
- Insert the CR2 battery, ensuring the correct polarity (+ and -) as indicated inside the compartment.
- Replace the battery compartment cover and secure it firmly.
3.2. Initial Fingerprint Registration (Administrator)
The first fingerprint registered will be the administrator fingerprint, which is required to add or remove other user fingerprints.
- Ensure the lock is unlocked and the battery is installed.
- Press and hold the fingerprint sensor for approximately 5-7 seconds until an indicator light (e.g., blue or green) begins to flash rapidly, or you hear a specific sound. This indicates it's ready for registration.
- Place the pad of the finger you wish to register firmly on the sensor. Lift and place your finger repeatedly (typically 5-10 times) from different angles until the lock confirms successful registration (e.g., a solid light or a confirmation sound).
- Test the registered fingerprint immediately to ensure it unlocks the device.

3.3. Adding User Fingerprints
You can add up to 19 additional user fingerprints after the administrator fingerprint has been set.
- Wake the lock by briefly touching the sensor.
- Place the administrator's registered finger on the sensor and hold it until the indicator light changes (e.g., a slower flash or a different color), indicating it's in 'add user' mode.
- Have the new user place their finger on the sensor, lifting and placing it repeatedly as done during administrator registration, until confirmed.
- Repeat for any additional fingerprints.
4. Operating the Lock
4.1. Unlocking
- Place a registered finger firmly on the fingerprint sensor.
- The lock will vibrate or emit a sound, and the indicator light will change (e.g., turn green) to confirm successful recognition.
- The lock mechanism will disengage, allowing you to open the chain.
4.2. Locking
The ABUS YARDO 7807F features an automatic locking mechanism.
- Wrap the chain around the object you wish to secure and your bicycle frame.

4.3. Securing Your Bicycle
For maximum security, always try to secure both the frame and at least one wheel of your bicycle to an immovable object, such as a bike rack, lamppost, or railing. Ensure the object is sturdy and cannot be easily cut or dismantled.
5. Maintenance
5.1. Cleaning
Regular cleaning helps maintain the lock's performance and longevity.
- Wipe the lock body and chain with a soft, damp cloth to remove dirt and grime.
- For the fingerprint sensor, use a clean, dry, lint-free cloth. Avoid abrasive materials or harsh chemicals.
- Do not immerse the lock in water, despite its weatherproof rating.
5.2. Battery Replacement
When the battery is low, the lock may indicate this with a specific light pattern or sound during operation. Replace the CR2 battery as described in Section 3.1.
5.3. Sensor Care
Keep the fingerprint sensor clean and dry for optimal performance. Moisture, dirt, or oils on your finger or the sensor can affect recognition accuracy.
