3. Operating the Lock

3.1 Multiple Unlocking Methods

The ARPHA D280 offers five convenient ways to unlock your door:

• Fingerprint Recognition: Utilize the advanced biometric sensor for quick, 0.3-second unlocking. The lock supports up to 50 unique fingerprints with a recognition rate of up to 99%.
• Keypad Password: Enter your personalized code on the illuminated keypad.
• Mobile App Access: Unlock the door with a tap on your smartphone via the ARPHA/Tuya mobile application (Bluetooth connection required).
• eKey Sharing: Share temporary or permanent digital keys with guests or service providers through the app.
• Mechanical Key Override: Use the physical backup keys for traditional unlocking, ensuring access even during power outages.

3.2 Anti-Peeping Password

To prevent others from guessing your password, you can enter random digits before and after your actual PIN code. The lock will still recognize the correct sequence within the longer string of numbers.

3.3 Auto-Lock and One-Touch Lock

The lock features an adjustable auto-lock function, which can be set from 10 seconds to 30 minutes, automatically securing your door after a set period. For immediate locking, simply press the dedicated one-touch lock button on the keypad.

3.4 App Control Features

Connect the lock to the ARPHA/Tuya mobile application via Bluetooth to access advanced features:

• View access entry logs.
• Generate one-time, permanent, or date-specific access codes remotely (with gateway).
• Receive low battery alerts.
• Manage user access and permissions.

Note: For remote management and Wi-Fi connectivity (e.g., Amazon Alexa, Google Assistant integration), an optional ARPHA GT gateway is required. Without the gateway, app control is limited to Bluetooth range.

4. Maintenance

In case of complete battery depletion, the lock features a Type-C emergency power port. Connect a portable power bank to this port to temporarily power the lock and gain access.

5. Troubleshooting

5.1 Common Issues and Solutions

• Lock not responding: Check battery levels and replace if necessary. Use the Type-C emergency power port or mechanical key.
• Fingerprint not recognized: Ensure your finger is clean and dry. Re-register your fingerprint if the issue persists. The sensor is highly sensitive, but proper placement is key.
• Keypad not lighting up: This may indicate low battery. Replace batteries.
• App connectivity issues: Ensure Bluetooth is enabled on your smartphone and you are within range of the lock. If using a gateway, verify its connection to Wi-Fi and the lock.
• Frequent battery changes: Ensure you are using high-quality AA alkaline batteries. If the issue persists, contact customer support.
• Lock losing connection: If the lock frequently disconnects from the app, especially when leaving for work, ensure the app is running in the background or consider purchasing the optional Wi-Fi gateway for more stable remote access.
