A:Answer Hi! To achieve the desired size of popcorn, press the Popcorn pad until it appears on the display window. One press will result in a weight of 3.5 oz (99 g), two presses will yield 3.0 oz (85 g), and three presses will produce 1.75 oz (50 g). The More/Less pad is optional. Finally, press Start to initiate cooking. The cooking time will appear on the display window and begin counting down after several seconds. Also, by using the More/Less Pad, the programs can be adjusted to cook popcorn for a longer or shorter time if desired. 1 tap = Adds Approx. 10 secs, 2 taps = Adds Approx. 20 secs, 3 taps = Subtracts Approx. 10 secs, 4 taps = Subtracts Approx. 20 secs and 5 taps = original setting. Hope this helps! -C
