System
The System function lets you adjust transmitter functions.
List
Two modes are available: Expert and Standard. The DX4S
defaults to Expert where all of the programming menus are
available. Standard mode eliminates the expert screens and
functions from the list, making it ideal for basic models.

F Rate (Frame Rate)
Frame rate is the response rate of the
receiver. The lower the number, the
faster the response. Frame rate only
affects the current model.
IMPORTANT: You should always use the fastest response
rate the servos can handle. This gives the lowest latency and
fastest response. If the frame rate is incompatible with the
servo, the servo will move erratically or in some cases not at
all. If this occurs, change the frame rate to the next highest
value.
The available frame rates will depend on the type of receiver the
DX4S is bound to:
DSMR: 11 or 22ms DSM: 11 or 16.5ms
DSM2: 11 or 16.5ms Marine: 22ms
1. Use the roller to highlight the F Rate function.
2. Press the roller.
3. Rotate the roller to select the frame rate and press the roller
to save the selection.
RS Port
This sets the port – (Bind or Aux (Auxiliary) – on the receiver for
ROSS (Remote Onboard Starting System) connection. RS Port is
model specific.
Username
You can program a user name with up to 8 characters. This
name is displayed on the Main Screen. In the System screen,
highlight the User Name and press the roller to access the
function. Use the roller to select the position, then press the
roller to access a character. Username affects all models.
