Sluggish Action

• Motor dirty or brushes worn

• Bind in drivetrain 

• Vehicle battery is not charged

• Check/clean/replace

• Clean/adjust

• Replace/recharge

Controls Reversed

• ST. REV or TH. REV

• Change switch position

Motor/ESC overheat

• Over-geared for the driving environment

• Install smaller pinion

Doesn’t Operate

• Transmitter batteries low

• Transmitter powered off

• ESC powered off

• Vehicle battery is not charged

• Replace/recharge

• Power On

• Power On

• Replace/recharge

Poor Range

• Transmitter batteries low

• Transmitter antenna is damaged or loose

• Receiver antenna damaged

• Replace/recharge

• Check/tighten

• Check/repair/replace

The system will not 

connect

•  Transmitter and receiver too near each other

•  Transmitter and receiver too near large 

metal objects (vehicles, etc.)

•  Receiver accidentally put in bind mode so 

receiver is no longer bound

• Move transmitter 8–12 feet (2.4–3.6m) from 

receiver

• Move away from large metal objects (vehicles, etc.)

• Rebind transmitter and receiver

The receiver goes into 

failsafe mode a short 

distance away from the 

transmitter

•  Check the receiver antenna to be sure it is 

not cut or damaged

• Contact Horizon Product Support

•  Make sure receiver antenna is in an antenna tube 

and is above vehicle

The receiver quits re-

sponding during operation

• Low battery voltage

•  Loose or damaged wires or connectors 

between battery and receiver

• Completely recharge battery

•  Do a check of the wires and connection between 

battery and receiver. Repair or replace wires and/

or connectors

Receiver loses its bind

•  Transmitter accidentally put in bind mode, 

ending bind to receiver

• Bind transmitter to receiver

TROUBLESHOOTING GUIDE

BINDING 

Binding is the process of programming the receiver to recognize 

the GUID (Globally Unique Identifi er) code of a single specifi c 

transmitter. The DX2E and SR201 are bound at the factory. If you 

need to rebind, follow the instructions below.

1.  With the receiver off, insert the bind plug into the BIND port 

on the receiver.

2. Power the receiver through any other port. The orange LED 

will flash continuously, indicating the receiver is in bind mode.

3. With the steering wheel and throttle trigger in the failsafe 

positions, normally full brakes and straight steering (see the 

Failsafe section on this page for more information), press and 

hold the bind button and turn on the transmitter. The green 

LED on the front of the transmitter will flash within three 

seconds, indicating the transmitter is in bind mode. 

4. Release the bind button when the green LED flashes. 

Continue to hold the steering wheel and throttle trigger in the 

failsafe positions until the LED on the receiver glows solid.

5. The LED on the receiver will glow solid when the transmitter 

and receiver are bound.

6. Remove the bind plug and store it in a convenient place. 

You must rebind when:

•  Different failsafe positions are desired e.g., when throttle or 

steering reversing has been changed. 

•  Changing receiver types e.g., changing from a DSM

®

 receiver 

to a DSM2

®

 or Marine receiver.

•  Binding the receiver to a different transmitter.

Some Spektrum receivers, like the SR3001, 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.

FAILSAFE 

In the unlikely event that the radio link is lost during use, the 

receiver will drive the servos to their preprogrammed failsafe 

positions (normally full brakes and straight steering). If the receiver 

is turned on prior to turning on the transmitter, the receiver will 

enter failsafe mode, driving the servos to their preset failsafe 

positions. When the transmitter is turned on, normal control is 

resumed. Failsafe servo positions are set during binding (see 

binding a receiver above).
