This picture is of the version linked in Related Items but there is a very similar unit identified as N1 LIM Mode above the right hand knob. N1 is related to the engine thrust. Other Auto Throttle Units are labelled EPRL for Engine Pressure Ratio Limit which again is an indication of the thrust being developed by a turbofan engine.
