Control Panel Functions:
- WET: For moist or wet foods (not for liquids).
- ADAPTER: For vacuum packing with vacuum tubes and adapters (A, B, C) for external containers.

- STOP: Halts the current operation.
Basic Vacuum Sealing Steps:

- Firmly close the lid to lock it: Press down on both sides of the lid until you hear a click, indicating it is securely latched.
- Select mode and press button: Choose the appropriate mode (e.g., VAC+SEAL for general use, WET for moist food, SOFT for delicate items) and press the corresponding button.
- Remove bag: When the LED indicator light turns off, the process is complete. Open the lid and remove your sealed bag.
