INTRODUCTION
Spektrum’s DX3S features an integrated telemetry system
providing accurate speed/rpm, temperature and voltage
readings. Featuring DSM 2.4GHz technology, the DX3S
offers sophisticated software combined with an easy-to-
use one-touch Rolling Selector making programming
quick and easy. Spektrum technology offers a bulletproof
radio link that’s immune to internal (noisy motors/ ESCs,
etc.) and external interfering sources. No longer will you
have to wait for a frequency or worry about someone else
being on the same channel. With Spektrum when you’re
ready to race there’s nothing stopping you!

MODELMATCH/BINDING
The DX3S features ModelMatch (patent pending).
ModelMatch prevents a model from being operated when
the wrong model memory is selected. If the wrong model
memory is selected the receiver simply won’t respond to
the transmitter.
It’s necessary to program the receiver to a specific
model memory (called binding) so that the receiver
will only recognize and respond to that specific model
memory. See Page 16 for specific details on Binding and
ModelMatch.

SWITCHING RUBBER GRIPS
The DX3S is supplied with 3 different sized rubber
grips with the medium size installed on the transmitter.
Each grip’s size is identified with an “S” (small), “M”
(medium), or “L” (large) on the inside of the grip for
easy identification. To remove, simply lift the edge of the
grip and continue around the grip until it is completely
removed. To replace, align the tabs of the grip to the slots
in the handle and press the grip in place.
INSTALLING THE BATTERIES
The DX3S radio system is supplied with 4 AA alkaline
batteries required for operation that provide over 16
hours of run time. Many drivers prefer alkaline batteries
over rechargeable batteries finding it more convenient to
simply replace the batteries when depleted rather than
taking the time to recharge.

center-pin negative. This is opposite of many
chargers. Before using a charger, make sure
the connector is center-pin negative. This
can be done using a voltmeter. Also, unlike
conventional radio systems that use 8 cells to
power the transmitter, the DX3S uses 4 cells.
This is due to the electronics being more
efficient. When charging, be sure to use a
charger designed for 4 cells (a 4.8-volt battery
pack) when charging the transmitter. Many
drivers simply make a harness and use the
same charger used to charge their car packs
but turn the current rate down to 1 to 2 amps.

STEERING RATE
Steering rate, (also known as dual rate) allows on-the-fly
steeringtraveladjustmentstobemadeusingthesteering
rate knob. Steering rate limits the amount of travel of the
steering servo. The steering rate cannot be greater than
100% and will never exceed the amount of steering travel
set in the travel screen.
RECEIVER COMPATIBILITY
The DX3S features DSM technology and is also
compatible with most DSM Spektrum surface receivers.
COMPATIBLE SPEKTRUM RECEIVERS
The DX3S is compatible with the following DSM
receivers. It is not compatible with the SR3100 DSM2
receiver.
SR300 - 3-channel sport - SPMSR300
SR3000 - 3-channel standard - SPM1200
SR3001 - 3-channel Pro - SPM1205
SR3500 - 3-channel Micro Race - SPM1210
Note: The SR3000HRS (SPM1202) receiver
is designed to be used with Spektrum’s Futaba
HRS compatible module system only and is
not compatible with the DX3S.

RECEIVER CONNECTION AND
INSTALLATION
Typical Electric Installation
Typical Gas Installation
USING THE ROLLING SELECTOR
The Rolling Selector is pressed to access functions and
rolled to select specific features or to change settings
or values. Pressing and holding the Rolling Selector
for more than 3 seconds returns the display to the main
screen.
The DX3S features one-touch programming utilizing a
Rolling Selector. The Rolling Selector has three functions:
1. Pressing the Rolling Selector - enters the selected
function.
2. Rolling the Rolling Selector - highlights function or
changes settings and values when selected.
3. Pressing and holding the Rolling Selector for more
than 3 seconds from any screen - returns the display
to the Main Screen.
Programming is very intuitive and always starts with a
press on the selector, then a roll, then a press, then a
roll and so on. Most find that within a few minutes they
are able to easily program their car without reading the
instructions; however, to realize the full benefit of the
programming it is recommend that the manual be read.
Most racers find it is most convenient to use their thumb
when making programming changes as this allows for
one-handed programming, even allowing the car to be
runinonehandwhilemakingprogrammingadjustments
