Troubleshooting Guide - Spektrum DX18t Manuel D'utilisation

5. Remove and keep 2 screws from the installed throttle ratchet
strip.
6. Do not remove grease from plastic part under the strip.
7. Attach the strip to the gimbal using the 2 screws.
8. Tighten the spring tension screw to get desired stick tension.
CAUTION: Make sure no wires or components
are pinched or damaged while installing the back cover.

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
SPEKTRUM DX18t • TRANSMITTER INSTRUCTION MANUAL
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
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
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
Loss of power to the receiver during flight
System powered on and connected, then receiver pow-
ered off without powering off transmitter
Poor signal reception
Electronic feedback
Low power
9. Carefully close the transmitter case using the 4 screws and
re-install the hand grips.
10. Connect the battery to your transmitter.
Solution
Move powered transmitter a few feet fromthe aircraft,
disconnect and reconnect the flight battery to the
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
Replace/recharge batteries
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
Replace/recharge batteries
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
Rebind by performing binding instructions
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
