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,

Titus

code 01 is the seat switch
