5. Operating Instructions
The HARFO D02 Smart Deadbolt offers multiple convenient ways to lock and unlock your door.
5.1 Initial Setup and Programming:
Upon first power-up, the lock will guide you through the initial setup using its OLED display and voice prompts. This includes setting the master code and performing door handing identification.
- Follow the voice guide to set up your master passcode. This code is essential for all programming functions.
- The voice guide will prompt you to register fingerprints, passcodes, and access cards for regular users.
5.2 Unlocking the Door:
- Fingerprint: Place your registered finger on the fingerprint sensor. The lock will unlock upon successful recognition.
- Passcode: Enter your registered passcode on the touchscreen keypad, followed by the '#' key.
- Access Card: Present your registered access card to the card reader area on the lock.
- Mechanical Key: Insert the physical key into the hidden keyhole and turn to unlock.
- Virtual Password: To enhance security, you can enter random digits before or after your actual passcode. For example, if your passcode is 123456, you can enter **123456** or 7891234560. This prevents others from guessing your code by observing finger movements.
