EN 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. Raceware™ Firmware Updates The DX4C features an SD card reader, enabling you to update the transmitter when RaceWare firmware updates are available. Register your transmitter at www.SpektrumRC.
EN 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.
EN SRS4210 Receiver Connection and Installation You must install the receiver in the vehicle before binding the transmitter and receiver. The receiver can be mounted flat 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 flat 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.
EN Binding the Transmitter and Receiver In order to operate, the receiver must be bound to the transmitter. Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. When a receiver is bound to a transmitter/ model memory, the receiver will only respond to that specific transmitter/model memory. Binding and Calibrating the Receiver (AVC Receivers Only) You must calibrate the receiver each time it is placed in bind mode.
EN Using the Rolling Selector Press the Selector to enter a highlighted function. Roll the Selector to highlight a function or change settings and values when selected. Press and hold the Selector for more than 3 seconds in any screen to return the display to the List Screen or the Main Screen. Press Press Roll Turn To Enter, Choose or Exit a selection. To program, always start with a press on the Selector, then roll, then press, then roll, and so on.
EN Model Select function opens a model memory for control of a model or adjustment of saved settings. If you haven’t programmed a model memory, all settings will be at factory default. CAUTION: Do NOT change the model in Model Select while operating a model. Change of the model interrupts transmitter signal to the receiver and may cause a crash. B A A Model name (programmable in Name Screen). B Model memory number (20 available).
EN Expo A The Exponential (Expo) function affects the response rate of the steering, throttle and/or brake. A positive Steering Expo value, for example, decreases steering sensitivity around neutral to make it easier to drive at high speeds in a straight line while still allowing for maximum turning radius. While sensitivity with positive Expo is decreased around neutral, it increases the sensitivity near the end of travel.
EN Sub-Trim The Sub-Trim function allows electronic adjustment or centering of each servo to get the servo arm exactly perpendicular to the servo, or in the exact optimum desired position. Minor sub-trim values can be used to correct this offset inaccuracy. Sub-trim is adjustable for all channels. A B C CAUTION: Use only small sub-trim values so a servo’s maximum travel is NOT overdriven.
EN Switch The Switch Screen lets you assign 5 available switches to these special functions: ST trim Assigns a switch to adjust center or neutral so steering tracks straight. TH trim Assigns the throttle idle adjustment to switch. Adjust throttle neutral (idle) position for drag braking or rolling idle for some models. Decreasing idle can enable a drag brake. Increasing idle can keep a model rolling until the brake is used. Brake Assigns brake trim to switch. Full brake is the default.
EN System The System function lets you adjust transmitter interaction. Selections affect all saved model memories. A Username You can program a username with up to 10 characters. This name shows on the Main Screen. Username defaults to Spektrum. G About.... This shows the release level of the transmitter’s software. Refer to Memory Card instructions for updating transmitter software. H A small bar shows relative position of highlighted screen name in the list.
EN Reset The Model Reset function restores factory default settings for the active model memory. A Choosing No returns to the List Screen. B Choosing Yes affirms erasing saved settings for the active model memory and return of factory defaults. C A box shows around selected text. A C B IMPORTANT: Model information saved in a memory is erased when that model memory is copied over or reset to factory default settings. Active Vehicle Control (AVC) Options: A ST Gain B TH Gain C Priority 1.
EN Mixing The Mixing function lets Steering, Throttle or Aux Channel follow control input made to the Steering, Throttle or Aux channel. When a mix is enabled and the assigned input control is moved, the master (primary) channel sends output at the same time the slave (secondary) channel sends output. Output is sent to the model in the direction and to the position assigned in the Mixing Screen. Tip: You can only select the Aux channel as Slave in this screen when Steer Mix is inhibited.
