Setup
Before using your Oster Inspire Toaster Oven for the first time, please follow these steps:
- Unpack: Carefully remove all packaging materials, including any tape or protective film, from the toaster oven and its accessories.
- Clean: Wash the baking pan and broil rack in warm, soapy water. Rinse thoroughly and dry. Wipe the interior and exterior of the oven with a damp cloth.
- Placement: Place the toaster oven on a flat, stable, heat-resistant surface. Ensure there is adequate clearance (at least 4-6 inches) on all sides and above the oven for proper ventilation. Do not place it directly against a wall or under cabinets.
- Power Connection: Plug the power cord into a standard 120V AC electrical outlet.
- First Use Burn-Off: Before cooking food, operate the oven on the 'Bake' function at 450°F (230°C) for approximately 15 minutes. This will burn off any manufacturing oils and eliminate odors. A slight odor and smoke are normal during this initial use. Ensure the area is well-ventilated.
