- Connect a Power Bank:
- Plug a USB-C cable from a portable power bank into the terminal.
- Ensure the power bank is fully charged.

- Once power is supplied, enter your passcode, scan your fingerprint, use a key tag, or perform face recognition to unlock the door.
- Replace Batteries Immediately:
- After successfully unlocking the door, replace all batteries with new AA alkaline batteries (1.5V) as soon as possible.
Important Notes:
- Ensure the power bank is fully charged before use.
