SPEKTRUM DX3R USER GUIDE
Note
: The SR3000HRS (model # SPM1202)
receiver is designed to be used with Spektrum’s
Futaba HRS compatible module system only and
is not compatible with the DX3R.
Note:
Marine compatible DX3R transmitters can
be identified by the following logo located on the
back of the transmitter.

receIver Power systeM
requIreMents
Inadequate or intermittent power to the receiver that
is unable to provide the necessary minimum voltage
during operation is the number one cause of control
failures with Spektrum systems. Some of the power
system components that affect the ability to properly
deliver adequate power include:
• Receiver battery pack (number of cells, battery
construction quality, connector and state of charge)
bIndIng a receIver
Note
: The SR3100 operates in DSM2 mode and
is compatible with transmitters that utilize DSM2
protocol.
1. With the receiver off, insert the bind plug into the Batt/
Bind port in the receiver.
2. Power up the receiver. If using an electronic speed
controller the lead should be plugged into the throttle
port and the switch turned on. If a receiver battery pack
is used, plug the battery lead into any open port noting
the polarity.
3. Turn on the transmitter and make sure the transmitter is
in the desired model number that you intend to use.
4. Press the rolling selector to access the List screen.
5. Rotate the roller to highlight the Bind screen and press
the roller to access this screen.

press the roller to initiate the bind process and to store

• The ESC’s capability to deliver current to the receiver and
servos in electric vehicles
• The switch harness, battery leads, servo leads, regulators
etc.
All Spektrum receivers have a minimum operational
voltage of 3.5 volts. If the voltage drops below 3.5
volts, the system will cease control until power is
regained.
recoMMended Power systeM
test guIdelInes
If a questionable power system is being used (e.g.
small or old battery, ESC that may not have a BEC
that will support the servo’s current draw, etc.), it is
recommended that a voltmeter be used to perform the
following test.
Plug the voltmeter into an open channel port in the
receiver and with the system on, load the servos
(apply pressure with your hand) while monitoring
the voltage at the receiver. The voltage should remain
above 4.8 volts even when all servos are loaded.
For gas vehicles, tap and twist the Rx battery pack
while watching the voltmeter. Some battery packs
have poorly welded tabs that give only intermittent
power. Such a defect will show up during shock
and vibration, so this test will verify that the battery
construction is good.
tyPIcal range
Your system’s range can vary greatly due to your
installation and the environment. In most cases you
should be able to have full control of your vehicle to
the limits of sight (about 300 ft with a 1/10-scale car).
If range issues exist your installation can be optimized
by extending the receiver’s antenna as vertically as
possible locating it as high in the vehicle as practical
and also by routing the antenna away from any
onboard electronics.
then the transmitter will beep, indicating the process is
complete. The LED on the receiver should now be solid,
indicating a successful bind has taken place.
8. Remove the bind plug and store it in a
convenient place.
Note
: The only time it’s necessary to do a rebind
is if different failsafe positions are desired or if
the receiver is to be bound to a different model
memory.
Note
: Some Spektrum receivers like the SR3000
use a bind button rather than a bind plug. The
binding process is the same with this receiver;
however, instead of inserting the plug before
powering up the receiver, press and hold the
bind button while powering up the receiver to
enter bind mode.
receIver coMPatIbIlIty
The DX3R features DSM2 technology but is also
compatible with Spektrum DSM surface receivers and
Spektrum Marine receivers. When the fastest response
rate is desired, using the system with a DSM2 receiver
like the SR3100 is recommended as this combination
gives the lowest possible latency/quickest response
rate. During the binding process the transmitter
actually “learns” the receiver type (DSM, DSM2 or
Marine) and configures itself to transmit that protocol.
