- positive supply: 5 V or 10 V;
- potentiometer has to be installed in a way that in the "zero" position (straight
wheels), poti output voltage is in the middle of the electric range
corresponding to a full left-to-right transition of the steered wheels;
- install the potentiometer in a way that, when truck turns right, poti output
voltage increases;
- use "SET STEER MIN" and "SET STEER MAX" functions to record the
extremes (minimum and maximum) of the potentiometer range; see chapter
