It is not only the time that is lost. My microwave needs a complete configuration after power failure to set things like language of the display. Without a set language it just displays numbers. It doesn't even default to English. Expected better from such an expensive name brand unit.
Not quite as bad as my Panasonic inverter combi microwave oven.
It has a grill, and three power levels. It also has a six character display.
So, to display the grill power level, it shows "GRILL " followed by "RILL 1". That is, it scrolls a seven character message because it will not fit on the six character LCD. And you need to wait three seconds every time for it to start scrolling, *every* time you change the power level.
Nothing would have stopped them abbreviating it to GRL 1, or even just removing the space there...but nope. It scrolls the message. It's infuriatingly bad design and I encounter it on an almost weekly basis. I can guess the power level by pressing it a few times, but sometimes I'll miscount -- so I'll have to wait for it to tell me the setting.
