    Introduction

    Thank you for purchasing Spectrum’s DX3.0 radio system. The DX3.0 is designed to provide
    R/C racers with a bulletproof 2.4GHz spread spectrum radio link. With the DX3.0 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 DX3.0’s programming is user-friendly and offers the
    most important features and functions that racers demand. It’s important that you carefully
    read this manual before attempting to operate your DX3.0 system. For your convenience, a
    blank data sheet has been included in the back of this manual. Once you have input all the
    necessary data for a particular model, we recommend that you write that information down on
    the data sheet provided. This insures that, in the rare case of a memory failure, you will not
    lose your models’ setup data.
    For those who would like to get out to the track quickly with just the basic radio setup, please
    refer to the Quick Start section that follows.

    DX3.0 Quick
    Start Setup

    Included in this manual are in-depth instructions detailing all the steps and procedures
    needed to program each of the DX3.0’s functions. For those racers who want to get to the
    track fast, we have provided the Quick Start section below. Quick Start covers the basic
    programming information necessary to get you racing right away.
    Later, when you want to learn more about the specific functions of the DX3.0, refer to the
    appropriate page(s) in this manual for more detailed programming information.
    Note: If braking adjustment via Grip Dial A is required, refer to the third channel system
    setup mode (page 31) for instructions.

    Binding
    It’s necessary to program the receiver to a specific transmitter so that the receiver will only
    recognize that transmitter, ignoring signals from any other sources. If the receiver is not
    bound to a transmitter, the system will not operate. Also, during the binding process, the
    servo fail-safe positions are set.
    1. Make sure the transmitter and receiver are turned off.
    2. With the receiver off, press and hold the bind button on the receiver while turning on
    the receiver.
    3. Release the bind button when the LED flashes green.
    4. With the transmitter off, Place the transmitter steering wheel, throttle trigger and
    auxiliary channels in their desired fail-safe positions (normally brake and straightahead steering).
    5. Press and hold the bind button on the transmitter while turning on
    the transmitter.
    6. Release the bind button after the green LED flashes.
    After several seconds the LED on the receiver and the LED on the transmitter will quit
    flashing and remain solid, indicating that the binding process was successful. Once binding
    is complete, the system will automatically connect.
    Note: See page 5 for a detailed description of the binding process.

    DX3.0 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. The FCC requires that these systems be “smart”– incorporating collision
    avoidance such that when a system is turned on, it scans the 2.4GHz band and selects a
    channel that is not being used, then begins transmitting on that unused channel. 79 channels
    are available and the odds of one DSS spread spectrum system interfering with another are
    astronomically remote. The 2.4GHz spectrum has a capacity of 79 channels. In the unlikely
    event that the spectrum is full, the 80th system will not connect or cause any interference
    going into hold scan until a channel is free.

    Binding

    During the first installation, the receiver(s) must be bound to the transmitter. Binding is
    necessary to program the receiver(s) to distinguish its corresponding transmitter from
    others. Also fail-safe positions are transferred from the transmitter to the receiver during
    binding.
    It is necessary to bind the receiver to the transmitter during the first installation, and is
    recommended when the receiver is moved from one vehicle to another. Receivers can be
    re-bound to the same transmitter or to other transmitters an infinite number of times. Also
    multiple receivers can be bound to a single transmitter, common when using one transmitter
    to operate several models.
    Only bound receivers and transmitters can connect. During power-up, the transmitter scans
    for a free channel while the receiver scans for its bound transmitter. During the scanning
    process, LEDs on both the transmitter and receiver flash rapidly. When control is achieved,
    the LED remains on continuously.
    In the unlikely event that the link is lost during use, the receiver will drive the servos to
    their fail-safe positions that were preset during the binding process. If the receiver is turned
    on prior to turning on the transmitter, the receiver will enter the fail-safe mode, driving the
    servos to their preset fail-safe position. When the transmitter is turned on, normal control is
    resumed.

    To bind the receiver to the transmitter
    1. Make sure the transmitter and receiver are turned off

    6. Release the bind button after the green LED flashes.
    After several seconds the LED on the receiver and the LED on the transmitter will quit
    flashing and remain solid, indicating that the binding process was successful. Once binding
    is complete, the system will automatically connect.

    Antenna

    At 8.5 inches in length, the receiver antenna is significantly shorter than conventional
    antennas. The receiver has provisions that allow the antenna to exit the top of the receiver
    or at the end of the receiver. To switch antenna positions, it is necessary to open the case
    to change the antenna exit position. Like all antennas, it’s important to mount the antenna
    vertically. In most cases the antenna can be mounted inside the body with no loss of range.
    Mount the receiver antenna as recommended by the manufacturer of the vehicle, however, it
    may be necessary to trim the plastic antenna tube (included with your vehicle) to allow the
    antenna to extend at least 1/2” past the tip of the tube.
    Note: If desired, the antenna can be shortened (cut) to exactly 3.6” with negligible loss of
    range, and in some applications the short 3.6” length will make installation easier.

    R/C Safety
    Precautions

    For safe and reliable performance of your R/C model, please carefully read and follow these
    guidelines:
    1. Radio control models are not toys. They are capable of inflicting serious injury to
    people and property. Use caution at all times when operating your model.
    2. You are responsible for the safe operation of your R/C model. You must properly install,
    test and operate your model with a clear sense of that responsibility. Do not take risks
    that might endanger yourself or others.
    3. Running an R/C car in the streets is very dangerous to both drivers and models. Avoid
    running your model in areas occupied by full-size automobiles. To locate areas where
    you can safely operate your model, you should contact your local hobby shop for R/C
    tracks or clubs in your area.
    4. When running an R/C boat, keep it away from any swimmers, full-size boats, or wildlife.
    Also, watch carefully for fishing lines that can get tangled in the propeller.
    5. If at any time while operating your RC model you observe abnormal model functioning,
    end your operation immediately. Do not operate your model again until you are certain
    the problem has been corrected.
    CAUTION: Control of your model is impossible without sufficient voltage for the
    transmitter and receiver. A weak transmitter battery will decrease your range of
    operation and a weak receiver battery will slow servo movement and decrease
    your range of operation. Check your receiver pack voltage often to avoid losing
    control of your model.

    Lithium Battery
    Your DX3.0 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 36).

    Memory Backup Screen
    If the Memory Backup screen appears, this indicates the possibility of a memory issue or
    the lithium battery is dead. If you switch the power off and on again, and transmitter is in the
    default mode with all data lost, it is suggested that the DX3.0 transmitter be returned to the
    Horizon Service Center for servicing (see Warranty Information, page 36).

    The Auxiliary Channel 3 function of the DX3.0 allows you to select from 2 different types of
    Channel 3 servo travel movements, or to inhibit the Auxiliary Channel 3 function. Use the
    information below to select the correct Auxiliary Channel 3 function type for your particular
    installation. It is suggested the O function (factory preset) be selected for most applications.

    LN = The LN, or linear, servo travel function is designed to be used when an engine fuel

    mixture servo is required. This function is most commonly used with gas-powered R/C
    racing boats and is accessible through the Grip Dial A. In this function, the maximum travel
    of the servo is determined by the End-Point Adjust function, page 23. The servo neutral
    position can be altered proportionately via the Grip Dial A for fuel mixture adjustment. When
    activated, fuel mixture trim values are visible for the Direct Trim function, page 27.

    The Travel Adjust feature of the DX3.0 allows the maximum travel of both the steering,
    throttle and Channel 3 (optional) servos to be increased or decreased in each direction to
    achieve the exact servo movement needed. 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. This feature is very useful either to maximize servo travel or to reduce
    servo over-travel to eliminate servo binding (servo moves further than control mechanism
    allows), without the need for mechanical linkage adjustment.

    Throttle
    Deadband

    (Function Mode)

    The throttle deadband feature is used to reduce/eliminate the dead throttle area that exists at
    neutral to the starting point of throttle and from neutral to the starting point of braking. This
    area is sometime known as deadband. As more throttle trim (also known as static brake)
    is applied, more of the dead trigger area right off neutral exists. To eliminate the throttle
    deadband, adjust a forward value such that your vehicle’s wheels just start to turn when the
    trigger is slightly squeezed. This provides the most accurate feel and eliminates the dead
    area in the throttle. To eliminate the braking deadband, adjust the brake value such that
    your vehicle starts to slow down when the trigger is slightly pushed. This provides the most
    accurate brake feel and eliminates the dead area when braking.

    Exponential

    (Function Mode)

    The Exponential feature of the DX3.0 allows you to alter the response rate of the steering or
    throttle control around neutral without affecting the maximum amount of steering or throttle
    available. The adjustment range is from -100% to 0% (Linear) to +100%. Exponential is
    factory set to linear for both steering and throttle. Exponential is often used to settle down a
    car that is twitchy around center without giving up maximum steering response. The DX3.0
    provides both positive (increase sensitivity at neutral) and negative (decrease sensitivity at
    neutral) exponential values.

    Programmable
    Mixing
    (Function Mode)

    The DX3.0 offers two different mixing adjustments that allow for mixing one channel to another
    channel. The mixes available are Steering-to-Auxiliary Channel Mixing and Throttle-to-Auxiliary
    Channel Mixing. Each direction is independently adjustable. Popular use of this function
    includes 4-wheel steering and independent front and rear wheel brakes.
    For example, Throttle-to-Auxiliary channel mixing can be used for independent front and rear
    wheel brakes. Each time the throttle/brakes is moved, the auxiliary channel will move in the
    direction and to the value input being given by the throttle channel. Mixing is proportional, so
    small inputs to the throttle will result in small output from the auxiliary
    channel. The adjustment range is from -125% to 0% to 125%. If the rate is negative, the
    channel is mixed in the opposite direction.
    Both mixes share a single mixing “offset.” The purpose of the mixing offset is to redefine the
    neutral position of the auxiliary channel, which can be set using Grip Lever A when
    “LN” is selected in the Auxiliary Channel 3 function. If the “LN” selection is turned off in the
    Auxiliary Channel 3 function with an offset value currently present, the value will
    continue to act as a mixing offset until the value is either cleared or changed. If a mix is not
    required, it is strongly suggested the mixing rate be set for 0%, which is the default.

    Lap Timer

    (Function Mode)

    The Lap Timer function of the DX3.0 allows the recording of individual lap times based on a
    999 second up-timer. Up to 50 laps and times from 3.0 to 99.9 seconds can be stored in
    memory for review at a later time. The Lap Timer function will only be enabled and shown in
    Function mode if Grip Button C (System Mode) is set to “LA.” With the Lap Timer enabled,
    pressing the channel key will alternate between the Normal display screen and Up-Timer
    display screen.
    The Lap Timer is started by pressing Grip Button C. Once active, as shown by the blinking word
    “LAP,” pressing Grip Button C again will begin recording the time of the next lap.
    Note: A 3.0 second lap is the quickest lap allowed. This prevents accidental double pushing of
    Grip Button C when recording lap times. If more than 50 laps are recorded, each new lap will
    overwrite the oldest lap held in memory.)
    To stop the Lap Timer, press the Increase and Decrease keys at the same time. To restart the Lap
    Timer, press Grip Button C. To reset the Up-Timer, press the Channel key to show the Up-Timer
    display screen. With the Up-Timer stopped, press the Increase and Decrease keys at the same
    time to reset.
    To review or reset lap times you must be in the Lap Timer function mode screen. Upon entering
    this function, the screen will always show the last lap time recorded. Use the
    Increase or Decrease keys to view the desired lap(s).
    Note: If a recorded lap time is greater than 99.9 seconds, “OVR” will be displayed.

    Sub-Trim

    (Function Mode)

    The Sub-Trim function of the DX3.0 is an electronic trimming feature that allows the neutral
    position of the servo on either the steering, throttle or auxiliary channel (optional) 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.
    Although the Sub-Trim function is a very useful feature, it is suggested that only small amounts
    of sub-trim be used so that no unwanted, non-equal servo travel is created. It is suggested that
    less than 30 points of Sub-Trim be used during adjustment. If more than 30 points of Sub-Trim
    are required, it is suggested that a mechanical linkage adjustment be performed.

    To access the Direct Trim Mode function, turn the transmitter power switch on. Next, move
    the desired trim lever to be adjusted. The appropriate screen for the selected trim lever will
    be displayed. To adjust, simply move the trim lever in the desired direction until the correct
    amount of trim is achieved. Once the desired trim is achieved, the screen will return to the
    Normal display screen after approximately two seconds from the last trim input. If the Increase or Decrease keys are pressed any time during the two seconds, the system will return
    to the previous screen in use.

    Steering Trim
    (STC)

    The DX3.0 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 End-Point Adjustment values (page 23) remain
    completely independent from the steering trim, unless the trim value exceeds the selected
    end-point values. (For example: If trim value is set at 30 and end-point values at 15, steering
    trim will override/alter the end-point value.)

    The Steering Dual Rate Trim 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
    20% of the total end-point value established in the steering EPA function. 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. Please note that since the Dual Rate value shown
    in the “STG” screen is the percentage of the end-point value established in the steering EPA
    function, the value will not always increase or decrease each time the Grip Lever B is moved.

    The Brake End-Point 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.
    Please note that since the brake end-point value shown in the “BRK” screen is a percentage
    of the total braking value established in the End-Point Adjustment function (page 23), the
    value will not always increase or decrease each time the Grip Lever A is moved.
    Note: If Grip Lever A is assigned an Auxiliary Channel 3 function by selecting “LN” or “2P”
    with Grip Button C in use, the Brake End-Point Adjustment will not be available.
    To adjust the brake end-point value, move the electronic Grip Lever A either left (–) or right (+).
    As soon as the grip lever is moved, the BRK End-Point Adjustment screen will appear and will
