[sdiy] Korg Polysix KLM-366 switch position

The "Fixed Resistors Diagram" in the Service Manual shows the switch pushed down towards VR1, or in the same direction as the "Test" position of the switch on KLM367.

As to the purpose, there's a note in the adjustment procedure which might refer to it. It says:

"Switch SW1 to the front while playing C6 (stretch tuning) and confirm +8~+12 cent."

The usual tuning is supposed to be within 2 cents.

So which one is the standard position, and which one the position for the pitch adjustment. To the front (direction multipin connector) or to the rear (direction of the row of resistors)?
