2.4GHz TROUBLESHOOTING GUIDE
Problem Possible Cause Solution
Aircraft will not Bind
(during binding) to
transmitter
Transmitter too near aircraft during binding process
Move powered transmitter a few feet from aircraft,
disconnect and reconnect fl ight battery to aircraft
Aircraft or transmitter is too close to large metal object
Move the aircraft or transmitter away from the large metal
object
The bind plug is not installed correctly in the bind port
Install bind plug in bind port and bind the aircraft to the
transmitter
Flight battery/Transmitter battery charge is too low Replace/recharge batteries
Aircraft will not link
(after binding) to
transmitter
Transmitter too near aircraft during linking process
Move powered transmitter a few feet from aircraft,
disconnect and reconnect fl ight battery to aircraft
Aircraft or transmitter is too close to large metal object
Move the aircraft or transmitter away from the large metal
object
Bind plug left installed in bind port
Rebind transmitter to the aircraft and remove the bind plug
before cycling power
Aircraft bound to different model memory
(ModelMatch™ radios only)
Select correct model memory on transmitter
Flight battery/Transmitter battery charge is too low Replace/recharge batteries
Transmitter may have been bound using different DSM
protocol
Bind aircraft to transmitter
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
Replace or contact Horizon Product Support
Main and remote receivers too near each other
Install main and remote receivers at least 2 inches (51mm)
apart and perpendicular to each other
Receiver quits
responding during
operation
Low battery voltage Completely recharge fl ight battery
Loose or damaged wires or connectors between
battery and receiver Do a check of the wires and connection between battery and
receiver. Repair or replace wires and/or connectors
Receiver loses its
bind
Transmitter stand or tray could be pressing the bind
button If stand is pressing bind button, remove from stand and
rebind
Bind button pressed before transmitter powered on Rebind by performing binding instructions
Receiver slowly
blinking at landing
(DSM2 Only)
Loss of power to the receiver during flight Check battery voltage
System powered on and connected then receiver pow-
ered off without powering off transmitter
Power off transmitter when receiver is powered off
Flight log registers
undesirable number
of fades, losses or
holds or aircraft
responds irregularly
to controls
Poor signal reception
Reposition remote receivers for improved RF signal path
diversity
Electronic feedback
Check for and stop feedback from servos or motor systems
to the ESC or receiver
Low power
Check aircraft power draw and increase battery power or
decrease power demand by installed systems Ensure all
aircraft batteries are fully charged. nsure the installed BEC
for an electric aircraft is adequate for the power demand
