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.
