Looking at my old Eboard, with the pots on the left side:

The top pot turns around without stopping, so I can't tell you where to set it.

The middle pot will turn from 10 o'clock CW around to about 8 o'clock. Mine's set to about 6 o'clock.

The bottom pot has the same end points and is set to about 2 o'clock.

Be sure your wires are connected to the proper slots on the receiver.
