Thank you for purchasing Spectrum’s DX3 radio system. The DX3 is designed to provide
R/C racers with a bulletproof 2.4GHz spread spectrum radio link. With the DX3 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’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 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’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, 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 33) 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 6 for a detailed description of the binding process.

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.

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. See binding below for more details.
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 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
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

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.
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.
