I've got an Emerson microwave here. Pressing 1 immediately starts it cooking for 1 minute. There is no obvious button to push to enter a specific time. The proper button turns out to be labelled "power". Pressing this multiple times will cycle through the power settings, and then allows a time to be entered in the way you describe. Discovering this took Googling.
