I am new at a shop . They have a T 32 control . The tool eye don't work matter of fact , the soft keys are not even lit . Normally it HAS to be high lighted in the off position for it to even run . To me this means it was a problem before they bought it . so the parameter has been set to turn the eye off completely . Does anyone know what that parameter is to turn it on and off through the parameter is ? I know how to calibrate it just don't remember to one to use to turn it on and off .
