Well let me tell you , it doesent matter if you do or dont , there is no real support for thease applyances, they expect you to know how everything works. its real strate forward , put the meat in close it down and waite at least 3 min. its done its cooked. if you like well done leave it while longer. you like it rare pull mit out a little faster. Go for it experment. Bon Apiteart DFD
