Introduction
DX3.0 Quick
Start Setup
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.
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

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.
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.

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.
Steering tension is adjustable via the recessed screw located beneath the steering wheel (see page 9 for exact location). Turning the screw clockwise increases the steering tension.

Receiver Connections and Installation
Note: When using a separate Ni-Cd receiver battery as a power source, the operating voltage range is 4.8–6.0V (4–5 cells) underload.
Attention: Make sure the male and female connectors have the correct polarity (+/–) before connecting. Be sure to orient the servo plug correctly for proper insertion.
Most electronic speed controllers are set up for Battery Eliminator Circuit (B.E.C.) operation and plug directly into your receiver. See Figure A for a typical setup and check your speed controller’s manual for correct installation.
