THE RUBBER GRIP
This transmitter includes 3 sizes of grips. The medium-size grip is installed at the factory.

2. Align the tabs on the new grip with the slots in the handle.
3. Press the grip against the handle.
RACEWARE FIRMWARE UPDATES
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 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.
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.

WARNING SCREENS
Low Battery Alarm
An alarm will sound and a warning screen will show when the transmitter’s battery power goes below a set limit. This alarm reminds a user to bring the model under full control, power off the transmitter and replace batteries. Press the Roller to stop the alarm and go to the Main Screen.
Set the low battery limit using the System Screen.
Inactivity Alarm
An alarm will sound and a warning screen will show when the transmitter has been left on (approximately 10 minutes) without control movement. Moving any control will stop the alarm. This alarm reminds users to power off the transmitter and save battery power.
RECEIVER COMPATIBILITY
•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.

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.
SPEKTRUM DX4C • TRANSMITTER INSTRUCTION MANUAL
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.
EN
Install the Receiver in your vehicle using the included doublesided 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.

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 transmitter, 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.
