Tech sheet would be in a plastic bag on the back of your storage draw. Pull it out and unless someone scarfed it, should still be there. You can not just lift the top. Each burner will unscrew (1/4 turn) and pull up exposing a screw that holds the top down to the burner orifice support. Once you remove the burners, the screws, then the top will lift from the front up hinging toward the back.
But you do not need to lift the top to get to the control panel on this unit. It looks like a free standing model by the model (clock on the panel at the back of the stove). There will probably be a screw or two under the control panel on the left and right sides,small Phillips. Once you undo them, the panel should rotate up and dislodge allowing you to lift the control panel and clock up and rotate it down to access the backside of the clock. On this model since you do not have a touch pad, the clock is the issue.
