Thank you or purchasing Spektrums DX2.0 radio system. The DX2.0 is designed to provideRC racers with a bulletproo 2.4GHz spread spectrum radio link. With the DX2.0 DSM

system youll no longer have to wait or a requency clip, worry about radio intererence rom

noisy motors or ESCs or be concerned that someone may turn on a radio on your channelcausing intererence. In addition, the DX2.0s programming is user-riendly and oers themost important eatures and unctions that racers demand. Its important that you careullyread this manual beore attempting to operate your DX2.0 system.

For those who would like to get out to the track quickly with just the basic radio setup, pleasereer to the Quick Start section that ollows.

Introduction

Included in this manual are in-depth instructions detailing all the steps and proceduresneeded to correctly program each o the DX2.0s eatures. Quick Start covers the basic

programming inormation necessary to get you to the track ast. Later, when you want to learnmore about the specic eatures o the DX2.0, reer to the appropriate page(s) in this manualor more detailed programming inormation.

BndngIts necessary to program the receiver to a specic transmitter so that the receiver will onlyrecognize that transmitter, ignoring signals rom any other sources. I the receiver is notbound to a transmitter, the system will not operate. Also, during the binding process, theservo ailsae positions are set.

1. Make sure the transmitter and receiver are turned o.

2. With the receiver o, insert the bind plug into the BIND port on the receiver.

3. Power the receiver through any port. The green LED will fash continuously, indicatingthe receiver is in bind mode.

4. Hold down on the SCROLL and CHANNEL buttons while turning on the transmitter.To enter System Mode, press the SCROLL button until BND appears on the screen.

5. With the steering wheel and the throttle trigger in their desired ailsae positions, pressthe INCREASE and DECREASE buttons at the same time to enter bind mode. BND will

fash when in bind mode.6. Ater several seconds the LED on the receiver will quit fashing and remain solid,

indicating that the binding process was successul. Once binding is complete, thesystem will automatically connect.

7. Once the bind process is complete and beore power is cycled on the receiver, removethe bind plug rom the receiver and store it in a convenient place. Failure to remove thebind plug will result in the receiver going back into bind mode.

Antenna

During the rst installation, the receiver(s) must be bound to the transmitter. Binding isnecessary to program the receiver(s) to distinguish its corresponding transmitter rom

others. Also ailsae positions are transerred rom the transmitter to the receiver duringbinding. (See binding below or more details.)

It is necessary to bind the receiver to the transmitter during the rst installation, and is

recommended when the receiver is moved rom one vehicle to another. Receivers can bere-bound to the same transmitter or to other transmitters an innite number o times. Alsomultiple receivers can be bound to a single transmitter, which is common when using onetransmitter to operate several models.

Only bound receivers and transmitters can connect. During power-up, the transmitter

scans or a ree channel while the receiver scans or its bound transmitter. When control isachieved, the LED on the receiver remains on continuously.

In the unlikely event that the link is lost during use, the receiver will drive the servos totheir ailsae positions that were preset during the binding process. I the receiver is turnedon prior to turning on the transmitter, the receiver will enter the ailsae mode, driving theservos to their preset ailsae position. When the transmitter is turned on, normal control is

resumed.

T Bnd the Receer t the Transtter1. Make sure the transmitter and receiver are turned o.

2. With the receiver o, insert the bind plug into the BIND port on the receiver.

3. Power the receiver through any port. The green LED will fash continuously, indicating

the receiver is in bind mode.

Binding

At 3.6 inches in length, the receiver antenna is signicantly shorter than conventional

antennas. Like all antennas, its important to mount the antenna vertically. In most cases theantenna can be mounted inside the body with no loss o range. Mount the receiver antennaas recommended by the manuacturer o the vehicle, however, it may be necessary to trim theplastic antenna tube (included with your vehicle).

Binding(continued)

LED

The DSM system operates in the 2.4GHz band (thats 2400MHz). This high requency oersa signicant advantage as its well out o the range o model-generated radio intererence(like motor and ESC noise). All the complex issues that now exist using 27 and 75MHz

radios with model-generated interering noise are eliminated with this system. The DSMsystem uses Direct Sequencing Spread Spectrum modulation to generate a wide signal on asingle requency. The FCC requires that these systems be smart incorporating collisionavoidance 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 o n that unused channel. 79 channelsare available and the odds o one DSS spread spectrum system interering with another areastronomically remote.

While your DSM equipped 2.4GHz system is intuitive to operate, unctioning nearly

identically to 27 and 75MHz systems, ollowing are a ew common questions romcustomers.

1. Q: Which do I turn on rst, the transmitter or the receiver?

A: I the receiver is turned on rstall servos will be driven to their preset ailsaepositions set during binding. When the transmitter is then turned on, the transmitter scansthe 2.4GHz band and acquires an open channel. Then the receiver that was previously bound

to the transmitter scans the band and nds the GUID (Globally Unique Identier code) storedduring binding. The system then connects and operates normally.

I the transmitter is turned on rstthe transmitter scans the 2.4GHz band and acquires

an open channel. When the receiver is then turned on or a short period (the time it takes toconnect) all servos are driven to their preset ailsae positions. The receiver scans the 2.4GHzband looking or the previously stored GUID and when it locates the specic GUID codeand conrms uncorrupted repeatable packet inormation, the system connects and normal

operation takes place. Typically this takes 2 to 6 seconds.

2. Q: Sometimes the system takes longer to connect and sometimes it doesnt connect at all.

A: In order or the system to connect (ater the receiver is bound) the receiver mustreceive a large number o consecutive uninterrupted perect packets rom the transmitter.This process is purposely critical o the environment, ensuring that its sae to operate whenthe system does connect. I the transmitter is too close to the receiver (less than 4 eet) ori the transmitter is located near metal objects (metal Tx case, the bed o a truck, the top o

a metal workbench, etc.) connection will take longer and in some cases connection will notoccur. The system is receiving refected 2.4GHz energy rom itsel and is interpreting this asunriendly noise. Moving the system away rom metal objects or moving the transmitteraway rom the receiver and powering the system again will cause a connection to occur. This

only happens during the initial connection. Once connected, the system is locked in and,should a loss o signal occur (ailsae), the system connects immediately (4ms) when thesignal is regained.

PowerSystem TestGuidelines

Typical Range

Inadequate or intermittent power to the receiver that is unable to provide the necessaryminimum voltage during operation is the number one cause o control ailures with Spektrumsystems. Some o the power system components that aect the ability to properly deliver

adequate power include:

Receiverbatterypack(numberofcells,batteryconstructionquality,connectorandstateo charge)

TheESCscapabilitytodelivercurrenttothereceiverandservosinelectricvehicles

Theswitchharness,batteryleads,servoleads,regulatorsetc.

All Spektrum receivers have a minimum operational voltage o 3.5 volts. I the voltage drops

below 3.5 volts, the system will cease control until power is regained.

I a questionable power system is being used (e.g. small or old battery, ESC that maynot have a BEC that will support the servos current draw, etc.), it is recommended that a

voltmeter be used to perorm the ollowing test.

Plug the voltmeter into an open channel port in the receiver and with the system on, loadthe servos (apply pressure with your hand) while monitoring the voltage at the receiver. The

voltage should remain above 4.8 volts even when all servos are loaded. For gas vehicles, tapand twist the receiver battery pack while watching the voltmeter. Some battery packs havepoorly welded tabs that give only intermittent power. Such a deect will show up during shockand vibration, so this test will veriy that the battery construction is good.

Your systems range can vary greatly due to your installation and the environment. In most

cases you should be able to have ull control o your vehicle to the limits o sight (about 300t with a 1/10-scale car). I range issues exist your installation can be optimized by extendingthe receivers antenna as vertically as possible locating it as high in the vehicle as practicaland also by routing the antenna away rom any onboard electronics.

3. Q: Ive heard that the DSM system is less tolerant o low voltage. Is that correct?

A: All DSM receivers have an operational voltage range o 3.5 to 9.6 volts. With most

systems this is not a problem as most servos cease to operate at around 3.8 volts. Whenusing multiple high-current draw servos with a single or inadequate battery/ power source,heavy momentary loads can cause the voltage to dip below this 3.5-volt threshold thuscausing the entire system (servos and receiver) to brown out.

4. Q: Sometimes my receiver loses its bind and wont connect, requiring rebinding. Whathappens i the bind is lost in fight?

A: The receiver will never lose its bind unless its instructed to. Its important to understandthat during the binding process the receiver not only learns the GUID (code) o thetransmitter, but the transmitter learns and stores the type o receiver that its bound to.I the transmitter is placed into bind mode, the transmitter looks or the binding protocol

signal rom a receiver. I no signal is present, the transmitter no longer has the correctinormation to connect to a specic receiver and in essence the transmitter has beenunbound rom the receiver.

For sae and reliable perormance o your RC model, please careully read and ollow theseguidelines:

1. Radio control models are not toys. They are capable o inficting serious injury to

people and property. Use caution at all times when operating your model.

2. You are responsible or the sae operation o your RC model. You must properly install,test and operate your model with a clear sense o that responsibility. Do not take risks

that might endanger yoursel or others.

3. Running an RC car in the streets is very dangerous to both drivers and models. Avoidrunning your model in areas occupied by ull-size automobiles. To locate areas where

you can saely operate your model, you should contact your local hobby shop or RCtracks or clubs in your area.

4. I at any time while operating your RC model you sense abnormal model unctioning,

end your operation immediately. Do not operate your model again until you are certainthe problem has been corrected.

CAUTION: Control o your model is impossible without sucient voltage or thetransmitter and receiver. A weak transmitter battery will decrease your range o

operation and a weak receiver battery will slow servo movement and decreaseyour range o operation. Check your receiver pack voltage oten to avoid losing controlo your model.

The Sub-Trim unction o the DX2.0 is an electronic trimming eature that allows the neutralposition o the servo on either the steering or throttle channel to be moved, while allowingthe electronic trim lever or that channel to remain in the center position. This eature is very

useul, as it allows the servo arm/wheel position to be mo ved to help with control linkageinstallation, eliminating the need to make mechanical linkage adjustments. Although theSub-Trim unction is a very useul eature, it is suggested that only small amounts o sub-trim be used so that no unwanted, non-equal servo travel is created. It is suggested that less

than 30 points o Sub-Trim be used during adjustment. I more than 30 points o Sub-Trimare required, it is suggested that a mechanical linkage adjustment be perormed.

Accessng the Sb-Tr Fnctn1. Turn on the transmitter power switch.

2. Press the SCROLL key to enter the Function Mode.

3. Press the SCROLL key until TRIM appears in small letters to the let o the screen.

4. Press the CHANNEL key to select the channel to be adjusted(Steering, Throttle).

5. Press the INCREASEor DECREASEkey until the proper servo position is achieved.

The Direct Trim Mode unction o the DX2.0 is accessible through the use o the electronicthrottle or steering trim levers, as well as the two electronic grip levers (A&B) located onthe upper portion o the grip handle. This unction allows or quick trim adjustment o these

controls, without the need to access these unctions through the our keypad control keys.

To access the Direct Trim Mode unction, turn on the transmitter power switch. Next, movethe desired trim lever to be adjusted. The appropriate screen or the selected trim lever will

be displayed. To adjust, simply move the trim lever in the desired direction until the correctamount o trim is achieved. Once the desired trim is achieved, the screen will return to theNormal display screen ater approximately two seconds rom the last trim input. I theINCREASEor DECREASEkey is pressed any time during the two seconds, the system will

return to the previous screen in use.

The DX2.0 electronic Steering Trim lever, located just above the steering wheel, allows thecenter position o the servo to be manipulated in either direction to achieve precise centeringo the steering assembly. Steering Travel Endpoint Adjustment values (page 20) remain

completely independent rom the steering trim, unless the trim value exceeds the selectedendpoint values. (For example: I trim value is set at 30 and endpoint values at 15, steeringtrim will override/alter the endpoint value.)

To adjust the steering trim servo position, move the electronic Steering Trim lever either to

the let (+) or the right (-). As soon as the trim is moved, the STC Steering Trim screen willappear and will continue to be displayed unless the trim lever is untouched or a period otwo seconds. To reset the trim value to 0, press the INCREASEand DECREASEkeys at thesame time while the STC screen is displayed.

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 rom 100% through20% o the total endpoint value established in the steering EPA unction. This unction

is very useul in race conditions as it allows you to custom tailor the steering radius andsensitivity or the current track conditions. Please note that since the Dual Rate value shownin the STG screen is the percentage o the endpoint value established in the steering EPAunction, the value will not always increase or decrease each time the Grip Lever B is moved.

I the Emergency Steering button unction (page 17) is active, pressing Grip Button C willrestore the steering dual rate to 100% until the button is released.

To adjust the Steering Dual Rate value, move the electronic Grip Lever B either let (-) or right
