3. Debugging Instructions (for installation and debugging personnel only):

 - Door Opening Direction Setting: Press 1 for left-opening, press 2 for right-opening.

 - Aging Test: Press 4 (for 800 milliseconds).

 - Reverse Time Setting: Press 3.

Other Instructions for the Fully Automatic Smart Lock:

1. Lock Sound Alerts:

 - One long beep: Operation successful.

 - One short beep: Button prompt.

 - Two short beeps: Operation prompt.

 - Three short beeps: Operation failure.

 - Siren sound: Illegal operation/low voltage.

2. Password, Fingerprint, and Door Card Anti-Tampering: If the password is entered incorrectly more than 5 times (statistics by type, and the body sensor triggering incorrect face recognition 5 times), an alarm will sound for 15 seconds, which will automatically解除 after 180 seconds. It can also be解除 after correct verification.

3. Password Privacy Protection: Enter "XXXPasswordXXX" (add placeholder before the password, at least 6 digits, maximum 16 digits), and press the # key to confirm. The password must be part of the entered content.

4. Low Power Mode: The system automatically enters low-power mode after 8 seconds of no operation.

5. Low Battery Warning: When the voltage drops below 6.8V, the lock will warn, "Low battery, please replace it promptly." After the warning, the lock can be used for about 200 more unlocks. Battery replacement or charging should be done before the unlock count reaches zero.

6. External Power Supply: If the internal battery is depleted and the door cannot be unlocked, a 5V USB emergency charging port can be used for emergency unlocking (do not use when the battery has power).

Maintenance and Management of the Fully Automatic Smart Lock:

1. Daily Maintenance: Wipe the surface of the lock with a soft, clean, dry cloth. Do not use water, alcohol, or acidic chemicals for cleaning.

- Regularly ask professionals to lubricate the moving parts of the lock with oil or grease and replace worn-out components.

2. USB Emergency Power Use: If the lock's power is low and unlocking fails, connect an emergency power supply. After unlocking, immediately remove the emergency power source to recharge the battery (use only in emergencies, and do not use when the battery has power).

3. Handling Door Deformation: If the door deforms and the lock tongue cannot function properly, adjust the door plate position.
