Setup
- Unpacking: Carefully remove the toaster oven and all accessories from the packaging. Remove any protective film or packing materials.
- Placement: Place the toaster oven on a stable, heat-resistant, and level surface. Ensure there is at least 4 inches (10 cm) of clearance on all sides and above the oven for proper ventilation. Do not place it near flammable materials like curtains or walls.
- Initial Cleaning: Before first use, wipe the exterior with a damp cloth. Wash the baking rack and baking pan in warm, soapy water, rinse thoroughly, and dry. Do not immerse the main unit in water.
- First Use Burn-Off: It is recommended to run the oven empty for about 10-15 minutes on the "Bake" setting at 450°F (230°C) to burn off any manufacturing residues. A slight odor or smoke may be present during this process; ensure the area is well-ventilated.
