3. Setup and First Use
3.1 Unpacking
- Carefully remove the toaster and all packaging materials from the box.
- Remove any protective films or stickers from the toaster's surfaces, especially the touchscreen.
- Ensure all components, including the crumb tray, are present and undamaged.
3.2 Placement

- Lower the levers without bread in the slots.
- Allow the cycle to complete. Repeat 2-3 times in a well-ventilated area.
