What accessories should be used for Air Fry versus Dual Heat functions?

For Air Fry, use the air fry basket in the top rails, with or without the high-density pan in the bottom rails. For all Dual Heat functions, the high-density pan is required in the bottom rails — do not use another accessory without the pan installed. Using other accessories in the bottom rails during Dual Heat functions will result in temperature inaccuracy. (Pages 7, 9)
