Is it normal for a new (Out of the Box) Panasonic Microwave/Convection oven door to be a little difficult to open ?
It is normal for the microwave/convection oven door to be a little difficult to open the first time because of a cardboard spacer placed between the door and the control panel. Press the microwave's Door Release Button, then gently pull the door until it opens. Finally, remove the cardboard insert that kept the door secure during shipment.

What is Inverter Technology?
The inverter modulates the level of energy being transmitted by the oven to achieve a consistent level. So when you set 50% power, for example, you actually get a steady stream of 50% power for the entire cooking time. The result is more evenly cooked food, defrosting without cooked edges, and even the ability to keep foods warm until mealtime.
