2) Press the +/INC or DEC/- keys to move the Auxiliary Channel 3 servo Right or Left by the dened Step value. In addition,
Auxiliary Channel 3 servo travel in one direction can also be changed by pressing the Right MENU key.
TRM Switch
The TRM switch features its own specic Step Resolution function which is adjusted in the SETUP menu. This value overrides
the Step Auxiliary Step value. When using the TRM switch to control the Step Auxiliary function, the TRM Step Resolution
value should match the Step Auxiliary Step value. For example, if you choose a Step Auxiliary Step value of 10, you should also
choose a Step Resolution value of 10 in the TRM switch Step Resolution SETUP menu. For more information, see page 42.
Step Auxiliary servo travel is -100 to 100 and overrides End Point Adjustments programmed through the EPA menu.
The Four Wheel Steering Mixing function allows you to use Auxiliary Channel 3 as a second steering channel, allowing you to
use two separate steering servos for Front and Rear steering. The Four Wheel Steering Mixing function allows you to control either
the Front or Rear steering independently, or Mix the Front and Rear steering so that they can be used together. For example, if
your Rock Crawler uses Four Wheel Steering, you can use the Programming Keys to switch between Front or Rear Independent
Steering, Parallel Four Wheel Steering, and Tandem Four Wheel Steering. In addition, you also have the option of mirroring the
Channel 1 Steering Dual Rate, Exponential, and Servo Speed settings onto the Auxiliary Channel 3 Steering servo. This allows
for an optimum setup since Steering Dual Rate, Exponential, and Servo Speed settings will be the same for both servos.
Prior to programming the Four Wheel Steering Mixing function, the Auxiliary Lever should be in the OFF position (pushed
DOWN). Once programming is complete move the Auxiliary Lever UP to turn the function
ON or down to turn the function OFF. When OFF, the last Four Wheel Steering Mixing option
chosen using the Programming Keys will still be Active.

When using Four Wheel Steering, it's important that prior to programming to adjust the Sub-Trim values to center both
servos and to adjust the End Point Adjustment percentage values so that both servos travel the same amount. Auxiliary
Channel 3 Sub-Trim and End Point Adjustments can be made once the 4WS menu is selected. Simply ensure that the Auxiliary
Lever is in the OFF position (pushed DOWN), then press the Right or Left MENU keys to scroll to the SUB-T AUX and EPA
menus. For more information, see pages 36 and 19, respectively.
1) The TRM switch can be programmed to control the Step Auxiliary function. This

switch forward to move the Auxiliary Channel 3 servo in one direction and press the
TRM switch forward to move the Auxiliary Channel 3 servo in the opposite direction.
For more information, see page 41.
