• 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

BIndIng
Binding is the process of programming the receiver to recognize
the GUID (Globally Unique Identifier) code of a single specific
transmitter. The DX2E and SR310 receiver 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 DSMR
™
receiver to a DSM2
®
receiver.
• Binding the receiver to a different transmitter.
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).
