Hi In general there are no real schematics available on any of these compact Rb's.
Many of the extra post and jumpers are related to setting up the physics package. Without a very good understanding of what they do, you really can't touch them. Since the unit can be digitally tuned, I would guess you might find that it's set one step to high or low on the digital tune. The digital tune is easily reversed it you get it wrong ....
