Setup and Installation
Unpacking
Carefully remove the microwave oven from its packaging. Remove all packing materials, including the turntable and turntable ring. Inspect the oven for any damage, such as dents or a misaligned door. Do not operate the oven if it is damaged.
Placement
Place the microwave oven on a flat, stable surface that can support its weight and the heaviest food item likely to be cooked in it. Ensure adequate ventilation by leaving at least 10 cm (4 inches) of space at the back, 20 cm (8 inches) at the top, and 5 cm (2 inches) on the sides. Do not block any ventilation openings.
