Introduction Thank you for purchasing Spectrum’s DX2 radio system. The DX2 is designed to provide R/C racers with a bulletproof 2.4GHz spread spectrum radio link. With the DX2 DSM system you’ll no longer have to wait for a frequency clip, worry about radio interference from noisy motors or ESCs or be concerned that someone may turn on a radio on your channel causing interference. In addition, the DX2’s programming is user-friendly and offers the most important features and functions that racers demand.

DX2 with Digital Spectrum Modulation The DSM system operates in the 2.4GHz band (that’s 2400MHz). This high frequency offers a signiﬁcant advantage as it’s well out of the range of model-generated radio interference (like motor and ESC noise). All the complex issues that now exist using 27 and 75MHz radios with model-generated interfering noise are eliminated with this system. The DSM system uses Direct Sequencing Spread Spectrum modulation to generate a wide signal on a single frequency.

Display Screens (continued) Lithium Battery Your DX2 radio system is equipped with a ﬁve-year lithium battery backup system. This system is designed to protect and retain all radio programming in the event that the transmitter batteries drop below the required 9.0 volts, or the transmitter battery case is removed during battery changes. If after ﬁve years it becomes necessary to replace the lithium battery, return your system to the Horizon Service Center for repair (see address, page 31).

Accessing the System Mode To enter the System Mode, press both the MODE and CHANNEL keys at the same time while turning on the transmitter power switch. By pressing the MODE key, you can now select the model name input, data reset function as shown here on the System Mode ﬂow chart. Information for each function is located on the page number listed next to the function name on the ﬂow chart. To exit the System Mode, press the MODE and CHANNEL keys at the same time, or simply turn off the transmitter.
PAGE 16
Model Name Entry (System Mode) The DX2 allows a three-character name to be input for each of the two (2) models available. The current model, with name, will then be displayed in the Normal display screen. This feature is useful to help identify different models, setups, etc. For information on selecting models 1 or 2, please refer to the Model Select Function (page 19).
PAGE 17
Data Reset (System Mode) The Data Reset function allows you to reset all the programming in the selected model (1 or 2) to the factory default settings. Before using the Data Reset function, it’s important to enter the Model Select function and check to make sure the current model number indicated (1 or 2) is the model to which you want to reset to the factory default settings. The Model Select function is described in detail on page 19.
PAGE 18
Accessing the Function Mode To enter the function mode, it’s necessary to ﬁrst turn on the transmitter’s power switch. Next, press the MODE key until a beep is heard. The display will change to show the ﬁrst function listed on the Function Mode ﬂow chart as shown below. Press the MODE key to scroll down through the functions one by one, as shown in the ﬂow chart. Once the desired function has been reached, use the channel key to select the appropriate channel (if applicable).
PAGE 19
Model Select (Function Mode) The DX2 has memory for two (2) models. This feature allows for two different models to be operated with the same transmitter (additional receivers and servos must be purchased separately), or one model with two (2) different race setups.
PAGE 20
Travel Adjust (Function Mode) The Travel Adjust feature of the DX2 allows the maximum travel of both the steering or throttle. The adjustment range is from 0 % to 125%. The travel adjustment is factory set to 100% for both channels. The travel adjustment value displayed on the screen depends on the current position of the steering wheel, trigger, or trim lever to be adjusted.
PAGE 21
Travel Adjust (Function Mode) (Continued) Accessing the Travel Adjust Function To access the Travel Adjust feature, follow the step below: Press the MODE key until TRV ADJ appears on the screen Press the CHANNEL key to select the channel to be adjusted (steering or throttle) ENTER MODE Move the wheel/trigger or Grip Lever A in the desired direction and press either the INCREASE or DECREASE keys to achieve the desired travel value SYSTEM CHANNEL CLEAR INCREASE + DIRECT DECREASE – 1.
PAGE 22
Steering Rate (Function Mode) The Steering Rate feature of the DX2 allows the steering servo travel to be increased or decreased to the desired amount required. The values of the Steering Rate function are a percentage based from the travel adjust value set in the Travel Adjust section.
PAGE 23
Sub-Trim (Function Mode) The Sub-Trim function of the DX2 is an electronic trimming feature that allows the neutral position of the servo on the steering, throttle to be moved, while allowing the electronic trim lever for that channel to remain in the center position. This feature is very useful as it allows the servo arm/wheel position to be moved to help with control linkage installation, eliminating the need to make mechanical linkage adjustments.
PAGE 24
Servo Reversing (Function Mode) The Servo Reversing feature of the DX2 is a very convenient feature when setting up a new model. The purpose of the servo reversing function is to change the direction of the servo rotation in relation to the wheel/trigger movement. The Servo Reversing function is available for the steering and throttle of the DX2.
PAGE 25
Accessing the Direct Trim Mode The Direct Trim Mode function of the DX2 is accessible through the use of the electronic throttle or steering trim levers, as well as the two electronic grip levers (A&B) located on the upper portion of the grip handle. This function allows for quick trim adjustment of these controls, without the need to access these functions through the four keypad control keys. To access the Direct Trim Mode function, turn on the transmitter power switch.
PAGE 26
Steering Trim (STT) The DX2 electronic steering trim lever, located just above the steering wheel, allows the center position of the servo to be manipulated in either direction to achieve precise centering of the steering assembly. Steering Travel Adjustment values (page 20) remain completely independent from the steering trim, unless the trim value exceeds the selected endpoint values. (For example: If trim value is set at 40 and endpoint values at 30, steering trim will override/alter the endpoint value.
PAGE 27
Throttle Trim (THT) The DX2’s electronic throttle trim lever, located to the right of the steering wheel, allows the center position of the servo to be manipulated in either direction to achieve precise centering of the throttle trigger neutral position. Throttle endpoint adjustment values (page 20) remain completely independent from the throttle trim, unless the trim value exceeds the selected endpoint values.
PAGE 28
Grip Lever B: Steering Dual Rate Trim Adjustment STG The steering dual rate adjustment, located at Grip Lever B, allows the dual rate value (maximum servo travel) to be increased or decreased within a range from 100% through 40% of the total dual rate value established in the Steering Rate function (page 22). This function is very useful in race conditions as it allows you to custom tailor the steering radius and sensitivity for the current track conditions.
PAGE 29
Grip Lever A: Brake Endpoint Adjustment BRG Brake Endpoint Adjustment The brake endpoint adjustment, located at Grip Lever A, allows the maximum servo travel on the braking side of the throttle trigger to be increased or decreased from 100% to 0% (off). This function is very useful in race conditions as it allows the racer to custom tailor the “panic” brake value to maximize the car’s braking power for the current track conditions.
