3) Press the +/INC or DEC/- keys to set the desired Receiver Battery Fail Safe Voltage.
VOLTAGE setting range is 3.5v to 5.0v. The default value is INH (Inhibited)
The receiver will operate down to 2.5 volts, however, the minimum operating voltage of most
servos is higher than that. The voltage should be set to a value that will allow all of your servos
to operate at maximum output. You will need to check your servo's specifications to determine the
minimum voltage required for the compliment of servos you're using.

The Sub-Trim function allows you to correct the neutral trim setting for steering and throttle, making it possible
to center the trim switches while ensuring the steering and throttle servo horns remain centered. It's not
unusual that when you center a servo and install the servo horn, the servo horn is not perfectly centered.
The Sub-Trim function allows you to center the servo horn perfectly, without altering the servo End Point
travel. The Sub-Trim function can also be used for Auxiliary Channel 3 when it is being used with a Mix. For
example, you can use the Sub-Trim function to adjust the neutral trim setting of your front and rear steering
servos independently when the Four Wheel Steering Mixing function is used.

3) Press the Right or Left MENU key to highlight the SUB-T menu. ST 0 will be displayed in the
Programming Window.
Before adjusting the Sub-Trim function you should set the Steering Trim to '0' and the Throttle Trim to '0' using the Steering
and Throttle Trim switches.
2) Install the servo horn (or servo saver) onto your steering servo, making sure that the servo horn (or
servo saver) is as close to being centered as possible. In some cases, if using a servo horn, you can
get the servo horn closer to being centered by rotating the servo horn 180º and reinstalling it.
SUB-T ST setting range is 100L to 100R. The default setting is 0.
4) Press the +/INC or DEC/- keys to adjust the Steering Sub-Trim value to center the servo horn.
After adjusting the Steering Sub-Trim value, use the End Point Adjustment function to reset
the desired amount of servo travel in both directions. For more information, see page 16.
1) Set the Steering Trim to '0' using the Steering Trim switch. Push the Steering Trim
switch right to increase Steering Trim in one direction and push the Steering Trim
switch left to increase Steering Trim in the opposite direction. The current amount
of Steering Trim is indicated on the LCD in both digital format in the Programming
Window and in scaled format along the bottom of the LCD.
