A:Answer No clue what they meant. I just enter in the time and press start.
For express cook, you push 1, 2 or 3 depending on the number of minutes you want to express cook. There is a slight delay before it starts the express cook to see if you want to enter following numbers (i.e. 1:45). I like this because I've used some express cooks that automatically start when I actually want to put in another number.
As for adding time, it's super easy. You just hit the start button again and it adds 30 seconds. Or if you want to just do 30 seconds, just press start without pressing any other numbers.
