Dale W,
Edward is right about seat switch, but option six refer to auxiliary 2 speed which would sugest you have a four way control valve Im guessing at that, and re to speed settings for attachment 2 range 1-10 default value 1 could 1 in this case be re speed op6, if so cycling the DRS switch S to R toS will go through the options till the word done appears switch trk of wait awhile and switch trk back on this should give you a normal display, do not sit on the seat while you cycle the switch, you know you have to pull the stem of the DRS out before you cycle it,
