Do you mean a Panasonic 1250W microwave with 'Genius Sensor' technology? If so, you should check the model number on your microwave to find the correct manual.
Panasonic has several models with sensor modes. The manual will usually be on the product page. Search for the model from http://shop.panasonic.com
and scroll down to the manuals section. Alternately, go to http://shop.panasonic.com/support
, then do the model search. This will automatically go the the Owner's Manual section on the product page.
A manual for the NN-SN933 (and several other models) is here: ftp://ftp.panasonic.com/microwaveoven/om/nn-sn943_nn-sn933_nn-sn743_nn-sn733_en_om.pdf
. This is a 2.2 cu. ft. model that was advertised on target.com as a Genius Sensor microwave.
I hope this helps. Please add a comment with the model number of your microwave if you need a different manual.
CAN'T DO THAT. IT WON'T WORK.
If you cannot set the clock, the control board has a fault. Call an authorised Panasonic repair shop.
