5 The MC-509n is not the same as the Omron MC-509 Gentle Temp thermometer. Please find the Omron MC-509 Gentle Temp thermometer manual. Thanks. SuperDave

5 RE: the first comment: "The ManualsOnline team has found the manual for this product! We hope it helps solve your problem." ~They have NOT found the manual for this product. They found the manual for the MC-509 N. It is NOT the same as the MC-509. My thermometer continues to display < AL >, which is not to be found or described in the MC-509 N manual. Please find the correct manual. From all the posts on this item, it seems to be a pretty crappy piece of work.
