FUTABA 12K Instruction Manual page 191

The operation modes available when stick, trim
lever, or knob was selected are described below.
This mode sets ON/OFF to the left or right (up
or down) with the set point as the reference.
Left and right (up and down) operations are
symmetrical near the neutral position. For instance,
when you want to switch D/R with the aileron
stick, when the stick is moved to the left or right,
DR can be turned on at the same position.
The ON/OFF point can be shifted. ON/OFF at
a free position can be changed.
