With no operating manual included with this item, it was fun trying to figure out how to 





lower the power setting. Every microwave we have had in the past you pressed the power setting to reduce the power and then but in your cooking time . This model requires you to put the time in first then reduce the power setting.  This was not a great idea.  And if i did not go on line to ask the question of how to do it I may have never figured it out
