3. Setup
- Unpacking: Carefully remove the toaster and all packaging materials. Retain packaging for future storage or transport.
- Placement: Place the toaster on a stable, flat, heat-resistant surface, away from flammable materials such as curtains or walls. Ensure adequate ventilation around the unit.
- First Use: Before toasting food for the first time, operate the toaster empty for one cycle at the highest browning setting. This will burn off any manufacturing residues and eliminate odors. A slight smoke or odor is normal during this process.
