MAFT switch question??

[Pewter2K1]

Got a MAFT today, not the MAFT+ and i was looking at the on/off switch panel at the bottom and under the #2 it had ON=GN and OFF=Late Model... i put it on Late Model the #3 switch has ON=Limiter and OFF=No Limiter... Where does that switch have to be?? I didnt get directions for this thing... Thanks in advance to this.. and if anyone has any hints or settings that have proved well for them, please share... I do plan on auto tapping this while I tune, so i can monitor all this as it happens... THANKS!
