4.1 Unpacking
- Remove all packing materials from inside the oven cavity and from the oven door.
- Check the oven for any damage, such as a misaligned or bent door, damaged door seals and sealing surface, broken or loose door hinges and latches, or dents inside the cavity or on the door. If there is any damage, do not operate the oven and contact qualified service personnel.
- Ensure the glass turntable and turntable ring assembly are present and undamaged.
4.2 Placement
- Place the oven on a flat, stable surface that can support its weight and the heaviest food item likely to be cooked in the oven.
- Allow at least 4 inches (10 cm) of space on the top, sides, and rear of the oven for proper ventilation. Do not block any ventilation openings.
- Do not place the oven near a heat source, such as a range or oven, or in direct sunlight.
- Ensure the power cord is not pinched or damaged.
4.3 Electrical Connection
- Plug the oven into a properly installed and grounded 3-prong outlet. The voltage requirement is 120V, 60Hz.

5.3 Inverter Technology
Panasonic's Inverter Technology provides a continuous, consistent stream of microwave energy at all power levels. This ensures food is cooked evenly throughout, preserving texture and flavor, unlike traditional microwaves that cycle power on and off.
5.4 Genius Sensor Cooking
The Genius Sensor eliminates guesswork by automatically setting power levels and adjusting cooking or defrosting times. It detects the amount of steam produced by the food and signals the microprocessor to calculate the remaining cooking time for optimal results. To use, select the desired auto-cook menu item (e.g., Popcorn, Auto Reheat, Auto Cook) and press Start.
5.5 Auto Cook Menus
Utilize the dedicated buttons for common food items:
- Popcorn: For popping microwave popcorn.
