Steering Trim
(STC)
The DX3.0 electronic Steering Trim lever, located just above the steering wheel, allows the
center position of the servo to be manipulated in either direction to achieve precise centering
of the steering assembly. Steering Travel End-Point Adjustment values (page 23) remain
completely independent from the steering trim, unless the trim value exceeds the selected
end-point values. (For example: If trim value is set at 30 and end-point values at 15, steering
trim will override/alter the end-point value.)
To adjust the steering trim servo position, move the electronic Steering Trim lever either to
the left (+) or the right (-). As soon as the trim is moved, the “STC” Steering Trim screen will
appear and will continue to be displayed unless the trim lever is untouched for a period of
two seconds. To reset the trim value to 0, press the INCREASE and DECREASE keys at the
same time while the “STC” screen is displayed.
Each click will provide 0.3° of trim to the center of the steering servo with a maximum of 12° allowed.
Note: Each click will not always result in a change of the value displayed.
