6.3. Advanced Features

• Virtual Password: When entering your passcode, you can input random numbers before and after your actual password to prevent others from guessing it. The lock will recognize the correct sequence within the longer string of numbers.

• Emergency Power: In case of complete battery depletion, use a power bank connected to the USB emergency power outlet to temporarily power the lock.
• Cleaning: Wipe the tempered glass panel and lock body with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish.
• Mechanical Key: Keep the mechanical keys in a safe place outside your home for emergency access.

8. Troubleshooting

• Forgot password: If you forget your password, you can use one of the alternative unlocking methods: your registered fingerprint, an IC card, or the mechanical keys. You can also generate a temporary password via the Tuya app if the lock is connected to WiFi.
