THE RUBBER GRIP
This transmitter includes 3 sizes of grips. The medium-size grip
is installed at the factory.
To change the rubber grip
1. Lift the edge of the grip and pull the grip away from the
handle.
2. Align the tabs on the new grip with the slots in the handle.
3. Press the grip against the handle.
MODELMATCH
The Spektrum DX4C transmitter features ModelMatch™
technology, preventing you from operating a vehicle when the
wrong model memory is active in the transmitter. If you select
the wrong model memory, the receiver will not respond to
the transmitter.
1. Remove the grip from the back of the transmitter handle.
2. Download the latest RaceWare fi rmware from
www.SpektrumRC.com to an SD card. The transmitter serial
number can be found by going to the About screen.
3. Install the SD card in the card reader slot on the DX4C
transmitter.
4. Power on the transmitter. A Spektrum logo and an installation
bar will appear. Installation is complete when the Main screen
appears.
5. Power off the transmitter.
6. Remove the SD card from the card slot on the transmitter.
7. Re-install the rubber grip on the transmitter handle.
The DX4C features an SD card reader, enabling you to update
the transmitter when RaceWare™ fi rmware updates are
available. Register your transmitter at www.SpektrumRC.com
to receive the latest information regarding RaceWare fi rmware
updates. To install RaceWare fi rmware updates on your DX4C

AVC – ACTIVE VEHICLE CONTROL
The Spektrum SRS4210 receiver features Active Vehicle
Control™ (AVC™) technology that responds similar to traction
control in full-scale vehicles. In addition to traction control, AVC
technology also increases steering stability during high speed
driving or while driving over rough terrain. As you increase the
AVC sensitivity, the system increases steering stability and
traction control, similar to reducing the amount of steering
rate in a computer transmitter. Reducing the sensitivity value
increases the amount of steering control from the transmitter.
The SRS4210 receiver also enables you to quickly turn AVC on
or off if you participate in organized racing.
NOTICE: You must use digital servos with the SRS4210
receiver. Using analog servos will reduce the performance of
the system and may cause analog servos to overheat.
AUX CHANNELS
The Aux channels can operate as additional servo channels, or
as a power supply for a personal transponder. If AVC technology
is active, only two channels, Steering and Throttle, are
operational. The Aux channels can be used to power a personal
transponder or lights.
If AVC is disabled (see DISABLING THE STABILITY ASSIST
FUNCTION to disable AVC), the Aux channels will operate as
servo channels.
• The DX4C transmitter is compatible with Spektrum™ DSMR™, DSM
®
, DSM2
®
, and Marine surface receivers.
• The Spektrum SRS4210 DSMR Surface receiver is compatible with all Spektrum DSMR transmitters and is also
backwards compatible with DSM2 transmitters. The SRS4210 receiver is NOT compatible with DSM transmitters.
• The SR410 DSMR receiver is ONLY compatible with DSMR transmitters.

SRS410 FAILSAFE
The throttle failsafe position is set during binding. In the unlikely
event that the radio link is lost during use, the receiver will drive
the the throttle servo to its pre-programmed failsafe position
(normally full brakes) and all other channels will have no servo
output. If the receiver is turned on prior to turning on the trans-
mitter, the receiver will enter the failsafe mode, driving the the
throttle servo to its preset failsafe position. When the transmitter
is turned on, normal control is resumed.
IMPORTANT: Failsafe activates only in the event that signal
is lost from the transmitter. Failsafe will NOT activate in
the event that receiver battery power decreases below the
recommended minimums or power to the receiver is lost.
SRS4210 FAILSAFE
In the unlikely event that the radio link is lost during use, the
receiver will drive the throttle channel to the neutral position. If
the receiver is powered on prior to turning on the transmitter, the
receiver will enter the failsafe mode, driving the throttle channel
to the neutral position. When the transmitter is turned on, normal
control is resumed.
IMPORTANT: Failsafe activates only in the event that signal
is lost from the transmitter. Failsafe will NOT activate in
the event that receiver battery power decreases below the
recommended minimums or power to the receiver is lost.
SRS4210 Receiver Connection
and Installation
You must install the receiver in the vehicle before binding the
transmitter and receiver. The receiver can be mounted fl at with
the label up or on its side. When you bind the receiver, the AVC
system automatically detects the orientation of the receiver. The
receiver must be mounted completely fl at when in the label-up
orientation or completely perpendicular when mounted on its
side. If the receiver is angled even slightly, AVC may not function
properly. If the orientation of the receiver is changed after
binding, you must then rebind for AVC to function properly.
Install the Receiver in your vehicle using the included double-
sided foam servo tape. Foam servo tape will hold the receiver in
place and help isolate it from vibrations.
IMPORTANT: Do not use hook & loop material to install the
SRS4210 receiver. Using hook & loop material will affect the
performance of the AVC system.
Mount the antenna up and away from the vehicle in an antenna
tube. The higher up the antenna is, the better signal it will
receive.
SR410 Receiver Installation
Install the receiver in your vehicle using double-sided foam
servo tape. Foam servo tape holds the receiver in place and
protects the receiver from vibration. Position the antenna
vertically and away from the vehicle in an antenna tube. The
SR410 and SRS4210 have a coax-style antenna. The last 31mm
of the antenna is the portion that receives the signal from the
transmitter.
CAUTION: Do not cut or bend the antenna. Doing so
could damage the antenna, resulting in the loss of
vehicle control.
Mount the antenna up and away from the vehicle in an antenna
tube. The higher up the antenna is, the better signal it will
receive.
