Hi Jordan,  If you are looking at the 2nd osc unit with the trimmers
closest to you (normal installed position) and the tuning tool slot is
running left and right (parallel to the front of the unit), the trimmer is
adjusted in the minimum or maximum  position.  So, if the tuning tool slot
is parallel to the sides of the unit (running front to back), it is set at
half value.

Regards, Larry
