Panasonic NN-SN671S user manual

1. Unplug the microwave from the power outlet for at least 1 minute.
. Plug the microwave back in.
3. Set the clock by pressing “clock” or “time of day” button, then enter the time and press “clock” or “start” again.
4. Test the microwave by heating some water for about 2 minutes to make sure it is working correctly again.
Note that this process might vary slightly depending on the specific model of your microwave. If you still have issues, it would be recommended to contact Panasonic customer service or professional for help. Check the user manual that came with your microwave for more troubleshooting methods.

To determine the age of your Panasonic microwave, you can follow these steps:
1. Check the label or tag: Look for a label or tag located on the back or side of the microwave. It typically displays various information, including the serial number, model number, and manufacturing date.
2. Look for a manufacturing date code: Locate the manufacturing date code on the label or tag. It usually consists of a combination of letters and numbers. This code represents the year and month of manufacture, or sometimes just the year.
3. Identify the date code format: Panasonic uses different date code formats, so understanding the format used on your microwave will help you decode the information accurately. It may differ based on the production year or model.
4. Decode the date code: Using the date code format, decipher the manufacturing date. For example, if the code is in the format MM YY, where MM represents the month and YY represents the last two digits of the manufacturing year, a date code of 05 18 would indicate the microwave was produced in May 2018.
If you are having difficulty understanding the date code or need further assistance, contact Panasonic customer support with your microwave's model and serial numbers. They should be able to provide you with the manufacturing date or additional information about your microwave's age.
