Panasonic microwave ovens come equipped with a Genius Sensor that allows you to cook foods by meal type: reheated or frozen foods, breakfast, lunch, snack, side dish or dinner. Once you engage the desired button, a preset time appears; press More-Less to change the time and press Start to begin cooking. The sensor beeps twice when it senses steam, and then displays the countdown to the cooking time. When the countdown has ended, the oven beeps five times. If you wish to stop cooking early, press Stop.
The inverter technology utilizes an inverter for power supply rather than a transformer or magnetic oil which leads to quicker, energy-efficient heating and defrosting.

Child Lock Feature
These microwaves also have a Child Lock feature that you must manually activate, but sometimes if you press certain buttons too many times, you can accidentally activate the child safety lock.
Turning the Child Lock on
Depending on the model you have, you must either press the Start button three times or for machines that have the Function button, press Function and the number 5 on the keypad, followed by the number 1.
Child Lock Off
To disengage the lock feature that disables the keypad, press the Stop-Reset button three times; for machines that include a Function button, depress the Function button, the number 5, and then the number 2.
Child Lock Test and Repair
To test the Child Lock feature after engaging it, simply press any button on the keypad. If you pressed the right buttons to engage the lock, and attempt to start the microwave by pressing any button on the control panel or keypad, the word LOCK appears in the display window of the control panel.
If you've pressed the correct buttons to disengage the lock feature, and it fails to disengage, unplug the machine and wait at least 10 seconds for the memory to clear before plugging in the unit again. The lock feature defaults to Off once the memory clears. If this fails to work, you will need to call a service technician. If H97 or H98 appear in the display window after the power reset, it signifies a problem with the system that generates the microwaves.
When Unfortunately, the operating instructions for the Panasonic Genius Sensor Microwave Oven (with inverter technology) are not available from Panasonic. To locate a user manual, use your search engine and search 'Panasonic Genius Sensor Microwave Oven user manual'. If you know the model number, which can be found in the right side of the inner door frame, be sure to include it in your search.
Other Cooking Issues
When the microwave fails to start, check its power source. Test the outlet by plugging a small alarm clock into the power outlet to ensure it is operational. If it is not, the circuit breaker may have tripped or a fuse may have blown. Replace blown fuses or reset the circuit breaker as needed.
Sometimes circuit breakers don't look tripped when they are. To ensure the circuit breaker is operational, flip it to the Off position, and then back to the On position. If it continues to trip, there is an overload to the circuit caused by the microwave or another appliance plugged into the same circuit.
