• Level the appliance: Make sure the microwave sits flat on a stable surface; adjust feet if provided.
• Inspect surroundings: Remove any items stored on top that may vibrate.
• Internal tightening (qualified persons): Remove the cover and tighten any loose screws on the transformer, magnetron, fan housing, and panels.
