Trigger Sizing Q R S Steering Tension Adjustment Trigger Sizing The steering tension is adjustable using the screw below the steering wheel. Turn the screw clockwise to increase the steering tension. You can adjust the trigger to fit your driving style. To adjust the trigger: Throttle Tension Adjustment 2. Adjust the trigger spacing as necessary.
EN Charging (not available on all transmitters) Charger Pigtail for Transmitter BLACK TO POSITIVE • Never attempt to charge dead or damaged batteries. BLACK W/WHITE STRIPE TO NEGATIVE Spektrum Transmitter Charge Jack Polarity - • Never allow children under 14 years of age to charge battery packs. + DX4R PRO transmitters with part numbers that end in E do not have charge jacks. • Never charge a battery if the cable has been pinched or shorted.
EN Warning Screens Low Battery Alarm Inactivity Alarm An alarm will sound and the voltage will flash on the main screen when the transmitter’s battery power falls below a set limit. This alarm reminds you to stop using the vehicle immediately; power off the transmitter and replace the batteries. Set the low battery limit using the System Screen. The alarm reminds you to power off the transmitter and save battery power.
EN Main Screen A The Main Screen displays information about the active model, including the Timer (when activated). To return to the Main Screen at any time, press and hold the Rolling Selector for at least 3 seconds. A. User Name B. Name assigned to the Model memory B C D C. Timers (when activated) E D. Transmitter Battery Voltage F E. Steering Percent G F. Position of Steering (St) trim H G. Position of Throttle (Th) trim I H. Position of Aux 1 trim J I. Position of Aux 2 trim J.
EN Model Select Select Copy Use the Model Select menu to change the model memory, to assign a model name or to copy a model. The DX4R PRO has 50 model memories available. CAUTION: NEVER change the model in Model Select while operating a model. Changing the model memory interrupts the transmitter signal to the receiver and may cause loss of vehicle control, damage or personal injury. The Copy function shares active model memory settings with a selected model memory space.
EN Steering Rate Steering rate (dual rate) allows you to make on-the-fly steering travel adjustments using any of the Programmable grip trimmers (A, B, C, D or E). The Steering Rate screen also offers a Steering override function, which allows you to access a second steering rate (normally 100%) at the touch of a button or trimmer.
EN Reverse Subtrim The Reverse function, also known as servo reversing, establishes the channel direction relative to the channel input. Use the reverse menu if, for example, the wheels turn left when you turn the steering wheel to the right. Reverse is available on all channels and is normally the first function you should test and adjust during programming. The Sub-Trim function enables you to correct minor servo arm offsets by electronically adjusting the center point of the servo.
EN BINDING Binding is the Process of teaching the receiver the specific transmitter’s code called GUID (Globally Unique Identifier) and storing failsafe values. When a receiver is bound to a transmitter/model memory, the receiver will only respond to that specific transmitter/model memory (see ModelMatch for more information). Frame Rate DSM Protocol Failsafe The throttle failsafe position is set during binding.
EN Servo Speed The Servo Speed function allows you to change the speed of any of the four channels— steering, throttle and Aux. from 100% (default) to 1%. The maximum speed is 100% and is fixed by the specifications of the servo itself. • In the List screen, use the roller to highlight the Servo Speed function. Press the roller to access the Servo Speed function. The Servo Speed screen appears. • Use the roller to select the desired channel, then press the roller to access that channel.
EN Brake Mix PROgrammable Mix Use the Brake Mix on large scale vehicles that require separate front and rear brake servos. The mix value creates brake bias between the front and rear brakes. Assigning the Brake Mix to a switch enables you to adjust the mix value from any screen. The Programmable mixes enable you to assign any channel as a Master or Slave, which is particularly helpful when you need to assign an Aux channel as a Master. 1. Select Aux1 or Aux2 as the Slavechannel.
EN Active Vehicle Control (AVC) Options If AVC is active, only two channels, Steering and Throttle, are operational. The Aux channels can be used to power a personal transponder or lights. • ST Gain • TH Gain If AVC is disabled (see Disabling the Stability Assist Function to disable AVC), the Aux channels will operate as servo channels. Aux channels are not available for use in mixes when AVC is active. • Priority 1. Select AVC from the LIST menu. 2. Change the State field to ACT . 3.
EN Idle Up Idle up (also called high idle) is used to advance the throttle position on a gas car during startup to prevent the engine from dying before the engine is warmed up. The following Parameters are available: State: Inhibit or Active Position: Adjusts the throttle position when idle up is engaged (0 to 100, default is 0) Alarm: Activates an alarm when the Idle Up is active The State must be Active to turn on the Idle Up function.
EN Reset The Model Reset function restores factory default settings for the active model memory. If after calibration the steering or throttle does not function properly (the travel is reduced or no servo travel), you will need to recalibrate the transmitter. • Choosing Yes affirms erasing saved settings for the active model memory and returns to factory defaults. A box shows around selected text. • In the List screen, use the roller to highlight the Reset function.
EN System The System function lets you adjust transmitter functions. Switch The Switch menu enables you to assign any of the seven switches to one of the following functions. Switches that have a +/- next to the name can be assigned to different directions. For example, ST trim+ causes right steering trim to trim the steering to the right. ST trim- causes right steering trim to trim steering to the left. Aux1 and Aux2 can only be assigned to one function at a time.
EN About Alert You can set an alarm to sound when the battery voltage gets to the limit set with the Alert. Battery voltage is displayed on the Main Screen. This screen displays the transmitter serial number (which is required when downloading firmware updates) and the release level of the transmitter’s software. Refer to Memory Card instructions for updating transmitter firmware. Menu: None, Tone, Vibe, Both Sets the alert type for scrolling through the menu items and selecting items.
EN GAUGES Receiver Battery (Tele: Batt) You can select which gauges to display on the telemetry data screen. The Batt, Temp and Speed gauges are displayed by default. The Lap gauge can also be added. The Battery Alert setting enables you to assign a low voltage warning. An alarm sounds when the receiver battery voltage drops below the assigned value. 1. Rotate the roller to highlight the box by each gauge. Temperature (Tele: Temp) 2.
