Spektrum SPM2020 DX2 - Manual (Page 26)

26
The DX2 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 Adjustment values (page 20) remain completely
independent from the steering trim, unless the trim value exceeds the selected endpoint
values. (For example: If trim value is set at 40 and endpoint values at 30, steering trim will
override/alter the endpoint 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 STT steering trim screen will
appear, and will continue to be displayed unless the trim lever is untouched for a period of
five seconds. To reset the trim value to 0, press the INCREASE and DECREASE keys at the
same time while the STT screen is displayed.
Press the INCREASE or DECREASE keys at the
same time to reset the steering trim to 0
