EN IDENTIFYING CONTROLS AND SWITCHES Function Function A Button A I Rubber Grip B Button B J Power Switch C Button C K Power LED D Button D L Battery Cover E Button E M Throttle Trigger F LCD Screen N Steering Wheel G Roller Selector O Antenna H Memory Card Port (under rubber grip) D C A O B F G Press power switch J to power ON the transmitter. The Power LED (K) will come on, a Spektrum logo screen will show, then the Main Screen will show on the LCD screen (F).
EN Rubber Grip This transmitter includes 3 sizes of grips and the medium-size grip is installed at the factory. Inside the grip is a letter showing size: L for large, M for medium and S for small. Remove the grip by lifting the edge of the grip and pulling the grip away from the handle. Install a grip by aligning grip tabs with handle slots and pressing the grip in place.
EN ModelMatch The DX3C features ModelMatch technology that prevents operating a model using the wrong model memory. During the binding process, the receiver stores code that is assigned to the specific model that is currently selected in the transmitter. For example: if the model that is selected in the transmitter is model #3, when a receiver is bound to that transmitter, the receiver will only operate when model #3 is selected.
EN PROGRAMMING GUIDE Roller and LCD Screen Use This transmitter features one-touch programming using a Rolling Selector. The Rolling Selector has three functions: Pressing the Selector - enters the selected function. Rolling the Selector - highlights function or changes settings and values when selected. Pressing and holding the Selector for more than 3 seconds from any screen - returns the display to the Main Screen. Some racers find it convenient to use a thumb to make programming changes.
EN Select 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 a receiver and may cause a crash. B Model 1: A NAME-01 A Model memory number (20 available). B Model name (programmable in Name Screen).
EN Expo 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 making 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 each of the 3 channels. 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 user name with up to 10 characters. This name shows on the Main Screen. User name defaults to Spektrum. 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.
EN Reset The Model Reset function restores factory default settings for the active model memory. A Choosing Yes affirms erasing saved settings for the active model memory and return of factory defaults. B A box shows around selected text. C Choosing No returns to the List Screen. CAUTION: Model information saved in a memory is erased when that model memory is copied over or reset to factory default settings.
EN Steer Mix Steer Mix function supports mixing Steering to Auxiliary channel so the Auxiliary input follows input to Steering. Steer mix is usually used to manage how much rear steering follows front steering inputs. Typically, this mixing function is used with 2 steering servos on trucks (front and rear servos). F/R (front/rear) type supports 2 mix rates so crab steering and four-wheel steering can be used momentarily with a switch. Dual type supports full-time mixing without a switch.
EN TROUBLESHOOTING GUIDE Problem The system will not connect Possible Cause Solution Transmitter and receiver too near each other Move transmitter 8 to 12 feet (2.4 to 3.6m) from receiver Transmitter and receiver too near large metal objects (vehicles, etc.) Move away from large metal objects (vehicles, etc.
