TROUBLESHOOTING GUIDE
Problem
Aircraft will not bind (during
binding) to transmitter
Aircraft will not link (after
binding) to transmitter
The receiver goes into failsafe
mode a short distance away from
the transmitter
Receiver quits responding during
operation
Receiver loses its bind
Receiver slowly blinking at
landing (DSM2 Only)
Flight log registers undesirable
number of fades, losses or holds
or aircraft responds irregularly to
controls
50
Possible Cause
Transmitter too near aircraft during binding process
Aircraft or transmitter is too close to large metal object
The bind plug is not installed correctly in the bind port
Flight battery/Transmitter battery charge is too low Replace/recharge batteries
Transmitter is a NX10 EU version and receiver is
DSM2
Transmitter too near aircraft during linking process
Aircraft or transmitter is too close to large metal object
Bind plug left installed in bind port
Aircraft bound to different model memory
(ModelMatch
radios only)
™
Flight battery/transmitter battery charge is too low Replace/recharge batteries
Transmitter may have been bound using different
DSM protocol
Damaged remote receiver or receiver extension.
Check the receiver antenna to be sure it is not cut
or damaged
Main and remote receivers too near each other
Low battery voltage
Loose or damaged wires or connectors between
battery and receiver
Bind button pressed before transmitter powered on Rebind by performing binding instructions
Loss of power to the receiver during flight
System powered on and connected, then receiver
powered off without powering off transmitter
Poor signal reception
Electronic feedback
Low power
Solution
Move powered transmitter a few feet from
aircraft, disconnect and reconnect flight battery
to aircraft
Move the aircraft or transmitter away from the
large metal object
Install bind plug in bind port and bind the
aircraft to the transmitter
The NX10 EU version is not compatible with
DSM2 receivers
Move powered transmitter a few feet from
aircraft, disconnect and reconnect flight battery
to aircraft
Move the aircraft or transmitter away from the
large metal object
Rebind transmitter to the aircraft and remove
the bind plug before cycling power
Select correct model memory on transmitter
Bind aircraft to transmitter
Required remote receiver is not connected
Replace or contact Horizon Product Support
Install main and remote receivers at least
2 inches (51mm) apart
Completely recharge flight battery
Do a check of the wires and connection
between battery and receiver. Repair or replace
wires and/or connectors
Check battery voltage
Power off transmitter when receiver is powered off
Reposition remote receivers for improved RF
signal path diversity
Check for and stop feedback from servos or
motor systems to the ESC or receiver
Check aircraft power draw and increase battery
power or decrease power demand by installed
systems. Ensure all aircraft batteries are fully
charged. Ensure the installed BEC for an electric
aircraft is adequate for the power demand
