Introduction
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.
DX3.0 Quick
Start Setup
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.
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.

R/C Safety
Precautions
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.

The Travel Adjust feature of the DX3.0 allows the maximum travel of both the steering,
throttle and Channel 3 (optional) servos to be increased or decreased in each direction to
achieve the exact servo movement needed. The adjustment range is from 0 % to 125%.
The travel adjustment is factory set to 100% for both channels. The travel adjustment value
displayed on the screen depends on the current position of the steering wheel, trigger, or trim
lever to be adjusted. This feature is very useful either to maximize servo travel or to reduce
servo over-travel to eliminate servo binding (servo moves further than control mechanism
allows), without the need for mechanical linkage adjustment.

Throttle
Deadband
(Function Mode)
The throttle deadband feature is used to reduce/eliminate the dead throttle area that exists at
neutral to the starting point of throttle and from neutral to the starting point of braking. This
area is sometime known as deadband. As more throttle trim (also known as static brake)
is applied, more of the dead trigger area right off neutral exists. To eliminate the throttle
deadband, adjust a forward value such that your vehicle’s wheels just start to turn when the
trigger is slightly squeezed. This provides the most accurate feel and eliminates the dead
area in the throttle. To eliminate the braking deadband, adjust the brake value such that
your vehicle starts to slow down when the trigger is slightly pushed. This provides the most
accurate brake feel and eliminates the dead area when braking.

Exponential
(Function Mode)
The Exponential feature of the DX3.0 allows you to alter the response rate of the steering or
throttle control around neutral without affecting the maximum amount of steering or throttle
available. The adjustment range is from -100% to 0% (Linear) to +100%. Exponential is
factory set to linear for both steering and throttle. Exponential is often used to settle down a
car that is twitchy around center without giving up maximum steering response. The DX3.0
provides both positive (increase sensitivity at neutral) and negative (decrease sensitivity at
neutral) exponential values.

Programmable
Mixing
(Function Mode)
The DX3.0 offers two different mixing adjustments that allow for mixing one channel to another
channel. The mixes available are Steering-to-Auxiliary Channel Mixing and Throttle-to-Auxiliary
Channel Mixing. Each direction is independently adjustable. Popular use of this function
includes 4-wheel steering and independent front and rear wheel brakes.
For example, Throttle-to-Auxiliary channel mixing can be used for independent front and rear
wheel brakes. Each time the throttle/brakes is moved, the auxiliary channel will move in the
direction and to the value input being given by the throttle channel. Mixing is proportional, so
small inputs to the throttle will result in small output from the auxiliary
channel. The adjustment range is from -125% to 0% to 125%. If the rate is negative, the
channel is mixed in the opposite direction.
Both mixes share a single mixing “offset.” The purpose of the mixing offset is to redefine the
neutral position of the auxiliary channel, which can be set using Grip Lever A when
“LN” is selected in the Auxiliary Channel 3 function. If the “LN” selection is turned off in the
Auxiliary Channel 3 function with an offset value currently present, the value will
continue to act as a mixing offset until the value is either cleared or changed. If a mix is not
required, it is strongly suggested the mixing rate be set for 0%, which is the default.

Lap Timer
(Function Mode)
The Lap Timer function of the DX3.0 allows the recording of individual lap times based on a
999 second up-timer. Up to 50 laps and times from 3.0 to 99.9 seconds can be stored in
memory for review at a later time. The Lap Timer function will only be enabled and shown in
Function mode if Grip Button C (System Mode) is set to “LA.” With the Lap Timer enabled,
pressing the channel key will alternate between the Normal display screen and Up-Timer
display screen.
The Lap Timer is started by pressing Grip Button C. Once active, as shown by the blinking word
“LAP,” pressing Grip Button C again will begin recording the time of the next lap.
Note: A 3.0 second lap is the quickest lap allowed. This prevents accidental double pushing of
Grip Button C when recording lap times. If more than 50 laps are recorded, each new lap will
overwrite the oldest lap held in memory.)
To stop the Lap Timer, press the Increase and Decrease keys at the same time. To restart the Lap
Timer, press Grip Button C. To reset the Up-Timer, press the Channel key to show the Up-Timer
display screen. With the Up-Timer stopped, press the Increase and Decrease keys at the same
time to reset.
To review or reset lap times you must be in the Lap Timer function mode screen. Upon entering
this function, the screen will always show the last lap time recorded. Use the
Increase or Decrease keys to view the desired lap(s).
Note: If a recorded lap time is greater than 99.9 seconds, “OVR” will be displayed.
To clear all lap times, press the Increase and Decrease keys at the same time.

Sub-Trim
(Function Mode)
The Sub-Trim function of the DX3.0 is an electronic trimming feature that allows the neutral
position of the servo on either the steering, throttle or auxiliary channel (optional) to be moved,
while allowing the electronic trim lever for that channel to remain in the center position. This
feature is very useful as it allows the servo arm/wheel position to be moved to help with control
linkage installation, eliminating the need to make mechanical linkage adjustments.
Although the Sub-Trim function is a very useful feature, it is suggested that only small amounts
of sub-trim be used so that no unwanted, non-equal servo travel is created. It is suggested that
less than 30 points of Sub-Trim be used during adjustment. If more than 30 points of Sub-Trim
are required, it is suggested that a mechanical linkage adjustment be performed.
