Starting from the centre position, the trim range is 20 increments in both directions.
The trim increment (step, or adjustment rate) can be set to any of the following
values: 0.5%, 1.5%, 2.5%, 3.5% (ControlFunctions > respective control
function, Step size parameter, see section 4.4 "4.4ControlFunctions main
menu" on page 118).
Switching the step size changes the trim value percentage since the number of
stored trim increments remains the same. This means if you alter the trim increment
size, you must remember to re-trim the model.
The design of the graphic trim display can be selected (Setup > Transmitter >
Screen, Trim graph parameter, see section 4.3.9 "Transmitter" on page 114).
