I have a 1870X Elmira electric/gas stv. , COOK'S DELIGHT, that I purchased in 1996, we cannot find the manual for the electric range. It has "hold" on the littler screen and I d do not know how to delete it.The control has 5 push knobs . Do you know the code to delete the "HOLD" display on the screen ? Thanks My email : herbertstotler@comcast.net.
