User Manual

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.

Introduction

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 straight-

ahead 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.
