The TINANA 5-in-1 Air Fryer Toaster Oven Countertop, 1300W 17 Qt, 4-Slice Convection Oven did not come with any instructions as to settings even though it came with three dials. One, to the far left said control temperature was in celsius and not fahrenheit , which added to the confusion. No booklet defining the purpose of each setting, as to amount of time, and temperature for best cooking results. Just a small print instruction booklet to warn about electric use, unplugging etc. NOT about settings for use.
