Setup and First Use
- Unpacking: Carefully remove the toaster oven and all accessories from the packaging. Remove any packing materials, stickers, or protective film.
- Placement: Place the toaster oven on a stable, heat-resistant surface. Ensure there is adequate clearance (at least 4 inches) on all sides and above the oven for proper ventilation. Do not place it near flammable materials.
- Initial Cleaning: Wipe the exterior of the oven with a damp cloth. Wash the baking pan, oven rack, and crumb tray in warm, soapy water. Rinse and dry thoroughly.
- First Use Burn-Off: Before cooking food, operate the oven empty for approximately 15 minutes at the highest temperature setting (450°F) on the "Bake" function. This will burn off any manufacturing residues and odors. A slight smoke or odor is normal during this process. Ensure the area is well-ventilated.
- Insert Crumb Tray: Slide the crumb tray into the bottom slot of the oven.
- Plug In: Plug the power cord into a standard 120V AC electrical outlet.

General Operation:
- Place food on the oven rack or baking pan. Ensure the crumb tray is in place.

- Oven Rack and Baking Pan: Wash these accessories in warm, soapy water. For stubborn food residue, soak them before scrubbing. Rinse and dry completely.
- Interior: Wipe the interior walls with a damp cloth and mild detergent. Do not use abrasive cleaners or scouring pads, as they can damage the non-stick coating (if present) or surfaces.

- Glass Door: Clean the glass door with a soft cloth and a glass cleaner or mild soapy water. Avoid harsh chemicals.
